Issue The standard graphic object does not exist in Vista 5 the same way it did in previous versions so an alternative method for creating a standardized graphic is necessary. Product Line TAC Vista Environment Vista Workstation TGML Graphics Cause The standard graphic object does not exist in Vista 5 as it did in earlier versions. Relative bindings and shortcuts replicate the functionality of having one graphic source file represent data from several different pieces of equipment. Resolution There are a couple of alternative methods to creating a standardized graphic that will work where many identical or similar devices exist. Below is an example of the first method. The scenario is a site where multiple Xenta 121 devices exist and each need individual graphics. In Vista Workstation locate the first Xenta 121 device in the folders pane on the left and right click and select New > Object > Graphic - TGML to create a new graphic that resides in the controller object.   Create a standardized graphic that uses naming conventions that are common to all of the devices that will use the graphic. In the example the actual SNVT names from the Xenta 121 are used for the point names. When the graphic is complete, save it and create the graphic bindings to the controller where the graphic resides.   From the bindings pane select all of the bindings then right click and select Apply Relative Address.   The addresses on the bindings will now only contain references to the points within the controller but will not have any reference to the controller name as shown below.   Close the bindings window and right click the graphic object and select copy.   Right click on the next device and select Paste Shortcut. Repeat this step for all of the relevant devices.   Now, clicking on the shortcut to the graphic from any of the devices will open up a copy of the graphic that is bound to the device in which the shortcut resides. The other is similar but places all of the shortcuts to the graphics in individual folders rather than down in the devices. It also requires that shortcuts be made in the folders to each of the devices. Create a graphic (use this graphic as a standard graphic) with relative bindings. Create folders for e.g. every room. In this folder, add shortcuts to the controllers, also add a shortcut to the graphic (with the relative bindings). By doing this you can have the function of "TGML standard Graphics" as in earlier OGC graphics.

Issue What are the Plain English program limitations when it comes to number of characters in the program and line label sizes? Product Line Andover Continuum Environment Plain English Editor Cause You must stay within the character limits of a Plain English program to have it execute without problems. Resolution Plain English program limitations for a CX9XXX level controller: Number of characters allowed in 1 line label: 16 Number of characters allowed per line: 140 Number of characters allowed in all lines labels (one program): 272  ** there is a 4 char overhead per line label Number of individual lines in (one program): 399 (including whitespace) Number of total characters: 31,728, approx. (this is really based on file size) Limitations for a Infinet/B3 level controller: Number of characters allowed in 1 line label: 16 Number of characters allowed per line: 140 Number of characters allowed in all lines labels (one program): 157  ** there is a 4 char overhead per line label Number of individual lines in (one program): 399 (including whitespace) Number of total characters: 10,725, approx. (this is really based on file size)

Issue The ETL job configuration tool freezes when running the load sources task under the mappings tab. Product Line EcoStruxure Building Operation Environment Extract Transform Load Administration Tool (ETL) Power Manager for SmartStruxure EcoStruxure Web Services (EWS) Enterprise Server Automation Server Cause The ETL default HTTP query size is set to 10 which in some cases can impact the performance of the tool. Resolution Make sure that you read through Energy Expert (Power Manager for SmartStruxure): Best Practices. This article will provide a lot of tips to avoid issues or improve system performance. ETL locks up while loading sources Adjust the HTTP query size to a higher value. This will reduce the number of queries between ETL and the SBO Server. Close ETL. Go to the location where ETL is installed. The default path is C:\Program Files\Schneider Electric\ETL X.X (SBO to PME). Under the Jobs folder there is a project file named "JOB_ETLProjectName.xml". Open this XML file with a text editor. Search for the setting called "ContainerQueryBatchSize". It is set to 10 by default, change it to 100 and save the job. Open the ETL user interface again and try running the Load Sources task. The folder count at the bottom of the screen will increase slower then before because each call is gathering ten times as much data. Note: If the ETL tool locks up again with the query size set to 100, try other values until it is able to complete the task such as 50, 25, etc. ETL takes a very long time to load sources When dealing with very large systems it can take hours for ETL to search through the entire database for all trends. To help reduce the searching time filters can be created to restrict what is exposed to EWS. Go to the System folder EcoStruxure Web Services > EWS Server Configuration. Click on the Filter Hardware Folder tab. Under the "Filter Hardware Folder by Path" section, click on the green addition symbol. In the pop up window, name the path filter and click create. Select the newly created filter path and click on the edit symbol. Enter the path of the folder or item in the database that you want to exclude from EWS. Click Okay. Note: All filter paths created here will NOT be searched by the ETL tool. Save changes. Once the ETL tool has loaded sources and the project has been created, the EWS filters may be removed.

Issue When compiling a WorkPlace Tech application, the error message "Error-Failed to create nci file" appears. Environment WorkPlace Tech Cause NCIs value is out of bounds. Resolution Typically, this occurs when an out-of-range "NA" or "NaN" value is written to a NCI by a Niagara station, LonMaker, LNC or some other head-end device. If this issue occurs, check the values of all NCIs on the application drawing.  Any NCI displaying out-of-range values (i.e. 1.#QNaN, 1.#INF or etc.) should be reset to normal values or "NA".

Issue The following error message appears when adding a LON application to a project in WorkPlace Tech 5.x from the pre-engineered "WPT Applications" zip file: AppXMLAddon Error Code: -2032465751 Code meaning: Unknown error 0x86DB08A9s. Environment WorkPlace Tech 5.x WPT Applications.zip Cause Workplace Tech encountered one or more values in the application that contain invalid characters. Generally, the most common value that causes this issue is the nciLocation SNVT. The value that should be in this SNVT is "/0", but through a previous Microsoft Visio conversion, it was replaced with a "vertical bar" character. Resolution Locate the invalid characters Replace them with valid ones or delete them. Once this is done, select "Application - Rebuild Application" from the drop-down menu.

Issue A Niagara R2 Enterprise Server station is extremely slow in starting, and there are hundreds of alarms. Is there a way to delete all the alarms? Product Line TAC IA Series Environment Niagara R2 Enterprise Server Cause Storing unwanted various alarms can cause the station to boot slow. Resolution The alarms can be deleted in two ways. The first method is to delete the app folder under the station directory. The entire historical content of the station will be deleted. This includes archived trends, alarms, and events. Follow the steps below to delete the app folder. Deleting the app folder to clear the contents of the database only applies to a Cloudscape installation. Open windows explorer and navigate to Niagara\station\[station name]\app Delete or move the app folder Restart the station The second method, is to use the appdb/queryForm servlet to selectively remove data from each table including alarms. This is done by using a web browser. Depending on the size of the database this method may take a substantial amount of time. Follow the steps below to delete data from the database by using SQL queries. Open a web browser and navigate to http://[ipaddress]/appdb/queryForm In the form, enter the following query - delete from event.eventhistory This will delete all history data in this table. For further information refer to the SQL_Tutorial\QueryExamples_10_6_04.pdf

Issue When should end-of-line (EoL) terminating resistors be installed on a BACnet/MSTP network? Product Line TAC IA Series Environment BACnet/MSTP network Cause Knowing where to implement the termination helps reduce signal reflections, which might cause issues in the system. Resolution Resistors of 120 ohm value must be installed at each end of a MSTP (or RS-485) trunk segment. They help reduce signal reflections and RF interference. Failure to install end-of-line resistors may result in intermittent communications.

Issue A Niagara R2/G3 UNC/JACE is rebooting every 15 minutes and the standard output window indicates AC Power status failed and a "Battery test failed" gets logged as well. Product Line TAC IA Series Environment I/A Series UNC, ENC or JACE chassis with Gel-cell backup battery Cause Marginal or failed battery or bad battery charging fuse Resolution The UNC automatically performs a battery load test every 15 minutes. If the voltage drops below a predefined value, the battery test indicates "battery test failed". If the voltage is higher than the predefined value, the battery test indicates "battery test passed". This message is only reported once unless the detected battery condition changes. A station alarm is generated only when the new outcome is different that the previous test. If a battery is marginal, the test may alternate between "passed" and "failed." Additionally, a bad or marginal battery has been known to cause random UNC reboots. Begin troubleshooting by checking the battery fuse (field replaceable only in the UNC-500/510 controllers), connections and voltage level.  If the battery voltage is low (less than 12 Vdc), disconnect the battery and monitor the UNC for errors or rebooting. If the errors or rebooting stops install a new battery.  After installing the new battery, measure the battery charging voltage.  The voltage reading should be between 13 and 14.5 volts DC if a good battery is connected.  If the installed battery is partially discharged, the charging voltage reading may be as low as 12.5 volts. In release 2.301.522, a change was made to how embedded controllers (UNC-410 / 500 / 510 / 520) perform the backup battery test.  Formerly, a "marginal" battery might result in continuous reboots. Now, the battery test is better coordinated with the AC power test. This prevents the scenario of repeated AC power fail shutdowns upon boot up if the battery is bad or weak.

Issue Is there a way to convert a Trane BCU (BMTW or BMTX) from BACnet/Ethernet to BACnet/IP for integrating to a Niagara R2 UNC? Product Line TAC IA Series Environment Trane BCU (BMTW or BMTX) Niagara R2 UNC Cause There are two components required to change over the BCU from BACnet/Ethernet to BACnet/IP. Resolution A special serial cable is required to download the BCU with the new configuration. Below are the pin outs to make the cable:     Access to the Tracer Summit software. Here are the steps for running the BCUconfig.exe program to change over the BCU from Ethernet to IP: Open Windows Explorer and navigate to C:\Program Files\Tracer Summit\Bin Double-click on BCUconfig.exe Enter the information and select download. Note - This is where you must have the Trane serial cable. The BCU will reset. Now change the Connection type in the Tracer Summit software to IP connection: Open the Tracer Summit software and select Connect. The Site connection Wizard will appear. Select the BACnet/IP radio button. From the Ethernet Configuration window, select the 'open on startup' check box. Select the 'Use BBMD connection' from the BACnet/IP configuration window. Specify the IP address of the BBMD BCU and the UDP port which is the BACnet port. Select Finish.

Issue Sample Plain English program to set up a door to allow for either keypad OR card validation. Environment Continuum Plain English Infinity NetController Cause Allowing the NetController to respond to a keypad as well as a card reader allows for flexibility in the security solution. Resolution How do I setup a door for keypad OR card validation Create the following InfinityProgram in the NetController for each door. Change each program to the correct door name.

The program needs to set also the EntryNoCommMode and possibly the EntryNodataMode. If the door is a dual reader door then the corresponding attributes on the exit side of the door must also be set.

Issue Problems encountered when changing Data Types(Elec Type) with Bacnet Points and using programs to perform COV's on those points Environment bCX Controller CyberStation Cause Data type (elec type) is changed without sending to the bacnet side will create issue. Resolution Changing the Data Type (Elec Type) of a point on the fly can cause issues. Once a point is created on the infinity side and sent to the data base on the bacnet side and a point is referenced from one or the other and a data type (elec type) is changed without sending to the bacnet side can cause issues. One of the issues is that data could quit updating. Another issue and one that is more noticeable is that if a COV subscription is created from one of the points through a program, the program could disable for one and or the data would not be correct or updated. To get an understanding of what goes on under the hood. Lets create a scenario that is a typical setup to see what is really going on. ------------------------------- I have a BCX with a B3 controller and have a point in the bcx named bcxPoint (binary data type). I have a point in the B3 named localPoint(binary data type) and a program named MirrorPrg. localPoint = myNet\MyBCX\bcxPoint Save this program and send to database on the bacnet side. Open the bcxPoint on the infinity side... change the value from 1 to 0 and back and forth while watching the value update on the bacnet side's localPoint. All is well and works as expected. Now change the data type on the bcxPoint to Analog and apply. Change the point form 1 to 0 and back and forth, notice that the point on the B3 localPoint on the bacnet side is not updating. But check the program and it is still running.(But not working) Depending if you have other points in a program that sent a COV notification your program can disable. But for our test, we'll force a COV subscription by adding a blank line to the program and saving, notice the program disables. NOTE: the program will appear to still to be running until a COV notification is sent. This caveat if you think about it makes sense. We subscribe to a COV list, but one of the data types changes without being sent to the bacnet side. On a larger scale lets say you have multiple points in the mirrorPrg and the program disables, not good. In order to correct the issue we described above, we can set the BCX's bcxPoint back to a binary type and perform a send to database on the bacnet side. Open up the program and add a line and then save which recompiles and puts out a new COV subscription. Don't forget to enable the program. The above is a workaround in case you get into trouble. But if you have many points you have changed, I would suggest deleting the controller from the bacnet side and then reloading the controller and the performing a find new bacnet devices. This will ensure that you have all data types straightened out. But to be on the safe side, if you are going to be changing data types of points, I would suggest deleting the point on the infinity side and perform a send to database on the bacnet side. This will get rid of all instances of the point. Then create the point with the correct data type and perform a send to database on the bacnet side and make sure you check all programs referencing the point.

Issue Unable to connect to a BCX configuration page Environment BCX Cause Note: This document is for some troubleshooting help, it is not a comprehensive BCX setup guide. Please refer to the BCX1 Technical Reference for detailed setup instructions. Resolution Are you going across a LAN or using a cross-over cable? If the BCX is on a LAN and was working before, remove the net cable from the BCX and try to ping the BCX. If you get a response then you have a duplicate IP. If it does not, you will need the help of the IT department to troubleshoot this problem. Are you on the same subnet? Make sure DHCP is disabled on your computer. Use a straight through or cross-over cable to access the BCX directly. Has this cable been used successfully before? If not then the cable could be the issue. 3. Reset the BCX to the default IP. The button is under the cover, top right. Be sure to hold down the IP reset button for about 20 seconds, holding it down for a couple seconds will not reset the IP to the default. Is the controller in bootloader mode? This can typically identified by observing the CPU light flashing rapidly,  approximately two times a second (2 Hz at 50% duty). Flashing the application through Cyberstation may fix this and enable you to get back into the controller. Ping the IP from a DOS prompt, can the BCX be pinged? Ex. Ping 169.254.1.1 Use Ipconfig /all to see your Internet Protocol settings. This will display the PC's current TCP/IP network configuration values. Are there multiple NIC cards? (Ex. Ethernet and wireless on a laptop) Disable the wireless adapter. We do not support a multiple NIC card configuration. Use Ethereal to perform a packet capture between your BCX and your computer. When the BCX starts it sends a gratuitous ARP that will indicate the IP address within the BCX. Was this after a power outage? Is the CPU light flashing amber and it was flashing green before and no one has flashed the controller? Is the CPU light solid amber? If so, you may need to send the controller to repair after trying the other options. Call Product Support Services and ask for assistance. If none of these options help then it may be necessary to send the controller to repair

Issue In firmware 2.19.1, the MPM Modbus Generic Driver feature has been introduced with little to no explanation on how to use it Product Line EcoStruxure Building Expert Environment Multi Purpose Manager (MPM) Cause Sample CSV file not available on MPM Resolution In order to establish communication with a modbus device, a CSV (comma separated values) file of a certain format must be uploaded to the GMC1 object. Once uploaded the file will be visible in the drop-down list.   Requirements and Limitations Only holding registers are supported at this time (Modbus function codes 3 and 16) The CSV file mast be renamed Modbus_[label].csv where label is the name of the device or a label to help identification (e.g. Modbus_SE8000.csv) Write only registers are not supported It is not possible to use a more than 32 bits variable in write mode It is not possible to leave a blank column in CSV register configuration file except the last column It is not possible to create a continuous register table using different variable types   The CSV file must have the following format: modbus_addr,register_type,label,access,factor,unit Download example here (The text file can be viewed in a text editor but its extension must renamed to csv before uploading it to the MPM) modbus_addr: modbus register address (Decimal number between 1 and 65535) register_type: "uint" (UI16) "int" (SI16) "float" (F32) "ulong" (UI32) "int64" (SI64) "uint64" (UI64) label: name for this register, this will also be used to populate the associated object in the MPM Alphanumeric value between 1 and 32 characters. No special characters (comma, simple quotes, double quotes,%,&,@,#, etc.) access: read or read_write. read will only poll register based on driver availability (30 seconds typical) read_write will monitor for a change of value of the associated point, which will then generate a write event to the device with this new value factor: multiplier / gain Float number, typical between 0.001 and 65535.

Issue Setting up the override value to show the damper feedback on an i2/B3 866-v Product Line Andover Continuum, EcoStruxure Building Operation Environment i2/B3 866-V Plain English Script Cause Activate the damper position feature in the 866-V. Resolution SBO: See this video on creating a program that calculates damper feedback position.  Also reference the article How to show damper feedback for an i2/b3 866-V which describes what needs to be done to show damper position and calibrate the damper. Sample objects, code and images showing configuration are supplied.   Continuum: There is a description in the 866-V installation manual on how to activate the damper position feature, but there are some additional pieces of information that this article has been created to address. This was initially to just get the feature working as mentioned in the next section below. Getting the damper feedback operational: Once the end stops are determined initially during the Learn process, the controller can then determine the position of the damper. Create a PE program to set the DamperOutput LCDState = Disabled and back to Enabled in the next line. This will run through its stroke to determine the end stops. ‘Example program named "damperstate" Fall thru, auto start ‘a 2 line program to initialize the stops Line 1 Set damper LCDstate to disabled goto 2 Line 2 Set damper LCDstate to enabled stop To run from the command line Run damperstate Note that the Feedback will not start working until the Damper has gone full stroke in both directions. This will take several minutes. Set the damper point to on or –on depending on the position so it will move Print Damper OverrideValue from a command line or display it on a listview of the damper output after adding the overridevalue column Self Calibration - The LCDState toggle actually activates the "self calibrate" process. It doesn't just enable the feature. It is necessary to know this because you will need to activate the self calibration again whenever the damper is manually moved using the red actuator clutch release button. Using the clutch can cause the damper position to be reported incorrectly. Periodic re-calibration should be as a part of normal procedure for the controller. Once the clutch is used, the damper position will still report, but the value may be incorrect. Re-calibrate recommendation- Use a PE program that recalibrates the damper (i.e. LCDState as mentioned in Section A) on manual command by the service technician on a power cycle or at the end of an occupancy period. Note: For controlling the Damper motor output create an Infinity Output point of type Triac on Channel 1. It can then be opened / Closed like any other Triac output with the use of On, -On or Off commands

Issue Are B-link or Infilink repeaters required every 32 nodes on an RS-485 bus when using i2 or b3 controllers? Infinet 1 controller had this requirement Environment Continuum Cause Infinity version 1 controllers required a repeater every 32 nodes. i2/b3 controllers do not have this same node count requirement. Resolution If you are going to be using i2/b3s with no 3rd party bacnet controllers on the segment, it’s less than 4000ft with approved cable, the runs are totally daisy chained without any "Y's" or "T's" in the network runs, then no Infilink/B-link repeaters are needed. The reason for this is that Continuum uses 1/10th load transceivers allowing the full 127 nodes to be used. If you are mixing b3s with 3rd party non-Andover controllers or mixing infinity version 1 infinet controllers with i2s, then you will need a repeater every 32 nodes and every 4000ft. If the distance exceeds 4000 ft, you will need a repeater.

Issue How do I change the Baud Rate of a field bus (either Infinet or Bacnet MSTP) if there is either an Infilink or B-link on the network? Product Line Andover Continuum, EcoStruxure Building Operation Environment Infinet BACnet Cause The Infilink and B-link must have their baud rate set manually. Resolution All Infinet or Bacnet B3 controllers autobaud on initial startup or when the fieldbus commport is changed from the parent controller's commport editor. The Infilink and B-link must have their baud rate set manually. The proper procedure to change the fieldbus baud rate is to first go to the commport editor and change the fieldbus baud rate. At this point a message is sent to all field bus controllers to change their baud rate. They will all change immediately, however the Infilink and B-link have not yet changed, so the bus will now be in a confused state and there will be offline issues. The next step is to go to the Infilink or B-link repeater and manually change the baud rate to the new setting. At this point the network should work normally, however if the procedure is not followed there may be network issues where you have some controllers that are running at different baud rates causing the network to be totally shut down. If this is the case the way to resolve the issue is to make sure the Infilink or B-link repeater is set to the desired baud rate and power down or reset those controllers on the network so that they will all synch up to the correct Baud Rate upon power up. ** Changing many controllers A method that may help when needing to change the baud rate of many controllers is to bypass the b-link Connect segment 1 of the b-link directly to the BCX comm port and change the baud rate Reconnect the B-link and verify the controllers are now online, repeat the baud change if necessary. Repeat this process for each segment You may still have some isolated controllers that need to be powered off/on.

Issue MNL-800 LON SNVT Programming Standards Environment Workplace Tech Tool software (any version) MNL-800 controller application Cause Problems occasionally arise as a result of improper LON SNVT programming and configuration in the MN-800 device application.  These issues include problems with the re-commissioning of the updated controller and potential network variable mismatch situations. Resolution  The following standards will prevent these problems from occurring. Network variables MUST be manually indexed. This prevents issues with the network variables becoming renumbered when application programming changes are made. (See NOTE 1) Change the application "Program ID" any time network variables are added or removed from an application.  To change the "Program ID" use the WPT Hardware Wizard,  (See NOTE 2) Select Hardware Wizard from Application Menu Click [Next] in MicroNet Setup Wizard screen Change the displayed program ID by entering a different program ID or adding a suffix letter/number. Maximum length is 8 characters. Click [Finish] to save the changed program ID and exit the MicroNet Setup Wizard.  In addition, one method of minimizing the need to repeatedly change the "Program ID" as the application is developed and debugged is to add a few extra common SNVT input and output definitions when first creating the application, leaving them unconnected to the application program.  If one of these SVNTs is needed, it is available in the LON network image (XIF file) and it is not necessary to change the "Program ID". If the MNL-800 controller has firmware version 2.0 (or later) installed, the standard nci network variables do not have to be indexed as the highest numbered SNVTs in the application.  It is perfectly acceptable to number them as the first 17 indexed SNVTs. Note that there are 17 standard network variables (12 nci, 2 nvo & 1 nvi), not just ten nci SNVTs. SNVT variable names should be limited to 16 characters or less.  Longer names are accepted by the WorkPlace Tech programming tool but the names will automatically be truncated by the LON Network Management tool when commissioning the controller. In addition, when programming the MNL-800 applications with the WorkPlace Tech Tool version 5.0, or later, it is not necessary to put each MNL-800 application in a separate project. NOTE 1: If using the WorkPlace Tech Tool version 5.8 or above, you can use the "Object Indexer" to automatically number all the network variables for you.  This tool also includes functions for detecting duplicate SNVT index numbers and for detecting gaps in the assigned index numbers. NOTE 2: If using the WorkPlace Tech Tool version 5.8 or above, you can set an option in the Hardware Wizard to automatically generate a new ProgramID and reindex the network variables when compiling the application.  Please be aware that this automatic generation of the ProgramID will require the Echelon network image for this device to be updated in any Echelon compatible network management tool.  Please refer to the documentation for the network management tool to determine what actions will be required. For example, if Niagara was used to manage the LON network, then the old shadow will need to be deleted, a new one added, and the device points rediscovered and the device re-commissioned.  

Issue Input scaling issues with the use of 0 to 5 Vdc and 0 (or 4) to 20 Milliamp transducers on a MNB controller. Environment MNB Series Controller application program using Analog Input voltage or current inputs. Cause The resolution of the Analog Input object value is determined by the maximum value that can be processed. If the scaled input range is less than 163.84, the output resolution is 0.01 If the scaled input range is greater than 163.84, the output is an integer value. Resolution When programming the Analog Input object in the WorkPlace Tech Tool, it is important to properly configure the input range and scaled value range for this object. If configured for a 0 to 5 VDC input, the sensor properties must be configured as follows: Input Sensor Type (Type): 5 - Volts Input Low Value (LInput): 0 Scaled Low Value (LScale): 0 Input High Value (HInput): 5 Scaled High Value (HScale): (value, up to 16383, corresponding to 5 volt input) See note below. If configured for a 0 to 20 milliamp or 4 to 20 milliamp input, the sensor properties must be configured as follows: Input Sensor Type (Type): 4 - Milliamp Input Low Value (LInput): 0 or 4 (depending on transducer) Scaled Low Value (LScale): 0 (value corresponding to LInput sensed value) Input High Value (HInput): 20 Scaled High Value (HScale): (value, up to 16383, corresponding to 20 milliamp input) See note below. NOTE: The HScale value should be set to give an output value for the Analog Input object that corresponds to the maximum temperature, flow, cfm, etc. that the sensor is measuring. The resolution of the value processed by this object must be taken into account when setting the HScale value because the input to output scaling and precision depends on this scaling constant. If the HScale value is less than 163.83, the input resolution is two decimal places and if greater than 163.83, integer resolution. An example of where this scale range is critical would be the use of a 0 to 5 volt air pressure transducer measuring an air pressure of 0 to 2 InWC. If the HScale is set to 2, the output would only resolve to 0.01. If the HScale value were set to 2000, the output would be in thousandths of an InWC, giving you an effective resolution of 0.001. Since this value is one thousand times the actual measured pressure, this 1000x scale factor would also have to be taken into account in any use of that value within the application.
