Issue When a user attemps to connect to the Sigma Server using a Web Client, the client connects, but the screen remains blank. Environment 4.08 3_46_57 3.46.57 Web Cause When Sigma 4.08 is installed, the installed version of LogonSE.swc is blank. Resolution Download the correct version of LogonSE.swc HERE. Shutdown the Sigma client and server. Navigate to Sigma/Data/Graphics/Drawings and delete LogonSE.swc. Copy the downloaded version of LogonSE.swc to Sigma/Data/Graphics/Drawings. Restart the Sigma client and server, and then test the Web Client.

Issue I have upgraded a BAS site to Sigma, but my controllers will not return correct values when using my Lookosn.rec files. Environment Sigma Cause Lookosn.rec are not used with Sigma. Resolution All controller specific tables must be copied to the universal Lookup.rec. These should be in the range of 1000 to 1999. By the use of 'Download Lookup Tables' from System Diagnostics, a local copy of Lookup.rec is sent to the controller.

Issue Every time the computer reboots, LMGRD errors are shown at startup.   LMGRD encountered a problem and needed to close. lmgrd.exe - Application Error The instruction at "0x0012e854" referenced memory at "0xffffff91". The memory could not be "written". Product Line Other, Satchwell MicroNet, Satchwell Sigma, TAC Vista Environment Vista Server 5.0 FlexNet Licensing Remote Alarm Manager Sigma BAS2800+ Micronet Errors Cause There is a known issue with the new license server from Flexnet. The LMGRD.exe is actually crashing during shut down of the PC. Resolution This is nothing dangerous. What happens is that when you turn off the PC, something is happening with the license server during the shutdown phase. Since LMGRD runs as service, it can not display this error message during this shut down. The error message is shown the next time the PC is started. It will not affect anything since the error messages is queued from the last shutdown sequence, NOT during the startup. We think it has something to do with having a license server installed and not using only an entitlement license. In some situations, placing a customer license file from any project into the license folder along with the monthly demo license stops the LMGRD error. The license server may read the customer license, note that it is invalid, then use the monthly license. Flexnet is looking into this issue. Look for a fix in upcoming versions. On Sigma, BAS2800+, and Micronet systems where Remote Alarm Manager is installed, the TAC license server can be uninstalled as it is not used.

Issue Can Sigma Logging Database be merged? Environment Sigma version 4.03 and 4.04 Cause There are currently no tools available on the open market suitable for merging the database as it's proprietary not "off the shelf." Resolution At Version 4.03 and 4.04 there are no means of combining Sigma Logging Databases.

Issue Can a USB connected printer be used a as a Live Alarm Printer configured for continuous printing? Environment Live Alarm Cause To provide the continuous printing function Sigma maintains a connection between the print queue and the printer, therefore keeping the port open and available at all times. Due to the way they operate, it is not possible for USB ports to remain open. Resolution It is not possible to use a USB printer for continuous printing.  The USB "Page Printing" option operates correctly. Please also refer to TPA-LOND-08-0012.00

Issue What PDAs (Personal Digital Assistants) are available for use with Sigma? Environment Sigma WINCE PDA Cause Supported PDA devices Resolution Version 4.01 WinCE (Build 3.36.24) software supported Dell Axim X51, X5, X3 PDAs which are now obsolete. The software was expected to work on other compatible PDAs providing they were running Windows Pocket PC 2002/3 or Windows Mobile Version 5. Version 4.04 WinCE software supports the following... Dell™ Axim™ X51 with Windows Mobile 5.0 iPAQ hx2490b with Windows Mobile 5.0 iPAQ 114 and the iPAQ 214 with Windows Mobile 6 Advantech TPC-30T panel mounting device with Windows CE 5.0.

Issue Sigma graphic only updates when first opened and no regular updates occur there after or only some graphic data values update. Product Line Satchwell Sigma Environment Sigma Controllers Cause A Sigma graphic update is controlled by the tolerance setting on the Sigma object and defines when the new value is transmitted from the controller to the server.  If the update does not occur, then the Tolerance value could be set to high. Resolution Reduce the tolerance value via the Sigma object editor. Download the object to the controller. Restart the graphic. Note:  Reducing the tolerance too far can lead to graphic updates dominating communications resources in the controller. For example; A temperature object can be set to 0.05 to give an update for every 0.1 degrees. A change of state programmable object should be set to 0.5 as it will returned true/false statement (equivalent to 1/0). A pressure sensor measuring Pascal’s (100's) may need the tolerance setting higher (e.g. 10) as pressure can change rapidly at higher values.  For globally changing the tolerance values for the Sigma objects, download the Sigma Tolerance Utility

Issue After making a changes to a Sigma multi-stage control loop do I have to download all the control object stages? Environment Sigma Client Object Editor. Cause Sigma Object Editor does not distinguish between the various control stages when downloading the multi-stage control object. Resolution No, Sigma Object Editor will down load all the Control object multi-stages (objects).

Issue After loading SigmaX on to a new laptop it does not run.  An error appears "The file SigInterfaceMfc.dll is not found." If accepted then another error message occurs, "The file SigShell.dll is not found." Product Line Satchwell Sigma Software Environment Sigma SigmaX Windows XP, 7, 10 Cause The Windows Environment Path "C:\sigma\bin" is not set when SigmaX was installed. Resolution Manually add the setting “c:\sigma\bin” to the Windows Environment Path. On Desk Top find the icon "My Computer". Using right hand mouse button select "Properties". Select the "Advanced" tab. Select the "Environment Variables" button. In the "System variables" window highlight the "Path" variable. Select the "Edit" button Scroll to the end of the "Variable value" text box and append the text string with “;C:\Sigma\bin\” Select "OK" buttons to close and save the changes (three times).

Issue After a Sigma Flexima has exported a CSV text file and then when opened in Windows Excel an error message occurs ‘File not loaded completely’ Environment Sigma Flexima, Microsoft Excel 2003 Cause Occurs because the Flexima export file contains more data than Windows Excel can load into one worksheet. Microsoft Excel 2003 is limited to 65665 lines of data; this is equivalent to a Flexima file size of approximately 1.5Mb. Resolution Reduce the size of the export file by running more frequent Flexima extractions from the Sigma Scheduler. Microsoft Excel 2007 or later has an increased capacity to 1,048,576 rows. Upgrade the excel version will resolve the issue.   

Issue Sigma remote client software has been added to new PC and the client will not connect to the Sigma server properly.  On some occasions the connection occurs but the Sigma Client Menu options are not available. Environment Sigma remote client (up to version 4.04), Windows XP, Windows 2000. Cause Sigma Software up to version 4.04 uses the Windows Share to allow the Sigma Remote Client to connect to the Sigma server.  The Windows share is not working correctly. Resolution 1.  Upgrade to Sigma 4.05 or above as this no longer uses the Windows Share to connect remote clients to the server. 2.1  If the software can't be upgraded then enable file Sigma file sharing between the PC’s by using a common Windows username and password on all the Sigma server/client PC’s. 2.2  Check the firewall/network will allow TCP port 3614 to be passed, unblock if necessary. 2.3 If the PC’s are on a client network then you may have to discuss this with the sites IT people to allow TCP port 3614 to pass through their routers/firewalls. 2.4 If the Sigma communications needs to pass through a firewall then port UPD 49152 will need to be unblocked.

Issue Advice on the configuration of a Sigma UNC 632, UNC 696 or UNC 796 controller, when connecting it to a "Flat" Ethernet network. Environment All Sigma controllers connected to flat ethernet network. Cause General advice. Resolution A "Flat" Ethernet network is a network that does not contain any subnets, for instance a network who's address is 10.158.0.0 Mask 255.255.0.0 will contain network addresses 10.158.0.1 to 10.158.255.254. On this type of network the Sigma device will only require an IP address and Subnet Mask to be entered. This information and details of the controllers "Default Server" are added to the controller using the SDCU (Sigma Device Configuration Utility).

Issue Advice on the configuration of a Sigma DNN (Distributed Network Node) when connecting it to a "Flat" Ethernet network. The DNN provides a communications route to Sigma controllers connected to an Ethernet or ARCnet sublan. Product Line Satchwell Sigma Environment Sigma Ethernet network Ethernet or ARCnet subnets Cause General configuration advice. Resolution A "Flat" Ethernet network is a network that does not contain any subnets, for instance a network who's address is 10.158.0.0 Mask 255.255.0.0 will contain network addresses 10.158.0.1 to 10.158.255.254. On this type of network the DNN will only require an IP address and Subnet Mask to be entered. This information and details of the DNN's "Default Server" are added to the device using the SDCU (Sigma Device Configuration Utility). If the DNN has RIP (Routing Information Protocol) enabled then it will broadcast the route to the sublan onto the network, if RIP is not enabled, then a persistent route must be added to the Sigma server. Please refer to Persistent routing on the Sigma server for more information.  To modify the DNN RIP settings, use the Pocket Terminal programme. RIP is enabled by default. To disable RIP on port 5 of the DNN. Start the Pocket Terminal programme. Enter RIPD 5 and select send. To enable RIP on port 5 of the DNN. Start the Pocket Terminal programme. Enter RIPE 5 and select send. To review the status of RIP Enter RIPS and select send

Issue Advice on the configuration of a Sigma UNC 632, UNC 696 or UNC 796 controller, when connecting it to a "Subnetted" Ethernet network. Environment All Sigma controllers connected to flat ethernet network. Cause General advice. Resolution A "Subnetted" Ethernet network is a network that contains a number of subnets, for instance a network who's address is 10.158.1.0 Mask 255.255.255.0 will contain network addresses 10.158.1.1 to 10.158.1.254. The IP address 10.158.2.1 will be connected to another subnet of that network. On this type of network the Sigma controller will require an IP address, Subnet Mask and the subnet Default Gateway to be entered. This information and details of the controller's "Default Server" are added to the controller using the SDCU (Sigma Device Configuration Utility).  

Issue Advice on the configuration of a Sigma DNN (Distributed Network Node) when connecting it to a "Subnetted" Ethernet network. The DNN provides a communications route to Sigma controllers connected to an Ethernet or ARCnet sublan. Environment Sigma Ethernet network Ethernet or ARCnet subnets Cause General configuration advice Resolution A "Subnetted" Ethernet network is a network that contains a number of subnets, for instance a network who's address is 10.158.1.0 Mask 255.255.255.0 will contain network addresses 10.158.1.1 to 10.158.1.254. The IP address 10.158.2.1 will be connected to another subnet of that network. On this type of network the Sigma DNN will require an IP address, Subnet Mask and a Static Route to be entered. The Static Route is entered using the Pocket Terminal programme and is entered as follows. SR+ 0.0.0.0/0 Default Gateway of subnet Ethernet  and the Ethernet port number, so, if the default gateway for this subnet was 10.158.1.254 and the Ethernet port number was 5, then the following would be entered using the Pocket Terminal programme.   SR+ 0.0.0.0/0 10.158.1.254 5 In this type of configuration it is generally necessary to disable RIP on the DNN, which is enabled by default. To disable RIP on port 5 of the DNN. Start the Pocket Terminal programme. Enter RIPD 5 and select send. As RIP is disabled, the sublan route is not broadcast to the network, and therefore  this routing must be added to the network routers. This requirement must be pointed out to the IT network administrators.

Issue Advice on adding a persistent route to the Sigma server PC. Product Line Satchwell Sigma Environment Sigma Server PC Cause General advice Resolution On a Sigma server connected to a "Flat" Ethernet network, where the system is using Ethernet or Arcnet communications via DNN's, and where it is not possible to run RIP on the DNN's, then it will be necessary to add a persistent route or routes to the Sigma server. A "Flat" Ethernet network, is a network that does not contain any subnets, for instance a network who's address is 10.158.0.0 Mask 255.255.0.0 will contain network addresses 10.158.0.1 to 10.158.255.254. To add a persistent route you must go to the Windows command prompt. This is achieved by selecting the Windows "Start" button, then the "Run" command and enter "CMD", a DOS window is now opened. At the DOS prompt type ROUTE ADD -P "Subnet address" "Mask" "DNN Ethernet IP address". So if the DNN Subnet was 192.168.1.0 mask 255.255.255.0 and the Ethernet IP was 10.158.1.6 then the persistent route would be added as below ROUTE ADD -P 192.168.1.0 MASK 255.255.255.0 10.158.1.6 To check that this has been correctly added enter "Route Print" at the command prompt, the route should have been added at the bottom of the list. Add a route for each DNN.
