Issue What is the unit load of the SpaceLogic SLP Room Units that will help me to calculate how many SLP Room Units that can be added on ComA and ComB of a SmartX Server. Product Line EcoStruxure Building Operation, Field Devices Environment SpaceLogic SLP Room Unit SmartX Server Cause Documentation does not state the Unit Load (UL) of the SpaceLogic SLP Room Unit. Resolution The Generic application note AN01 can be applied with answers to the transceiver interface attributes below. The SpaceLogic SLP Room Unit range use the SN65HVD1781DR transceivers which are a failsafe transceiver (not requiring bias) and reduced 1/10 UL. In addition there are no local bias resistors and therefore the 1/10 UL of the transceiver would be the total UL presented to the bus by the SpaceLogic SLP Room Unit. Transceiver Xcvr Unit Load Xcvr Failsafe Adaptor Circuit Bias Circuit Bias Load Total Unit Load Isolated 485 Bus SN65HVD1781DR 0.1 Yes None None 0.1 No Based on the above the total number of devices can be calculated as 32/0.1 = 320. The BACnet MSTP standard specifies that the address range for BACnet master devices is 0-127 and therefore a SmartX Server is limited to 127 devices per com port (254 total per Server) so this should effectively be the limiting factor. Since the SpaceLogic SLP Room Unit does not have an isolated RS-485 interface it conforms to Generic RS-485 Network Device Configuration 1 in EBO Webhelp.  A network consisting of only SpaceLogic SLP Room Units should only require a 120 ohm termination resistor at each end of the bus and not require any bias resistors. Also check out the SmartStruxure-RS485-Controller Unit Load Quick-Help video on the Exchange.

Issue Replacement actuator for the STL-SR valve Product Line Field Devices Environment STL-SR Cause Replacement actuator for a STL-SR valve Resolution A M800 actuator or MV15B-24 or MV15B-230 actuator can be used to replace the actuator on the STL-SR valve series. Click here for the STL-SR datasheet. Notes: The original actuator e.g. M5CP, may have had a potentiometer fitted to provide position feedback to the controller. There is no direct replacement, the controller, actuator and valve may have to be changed. As a workaround, The M800 provides a 2-10V feedback, using a signal conditioner this could be converted to a resistive feedback. The original actuator may have had end switches fitted, order end switches to suit the replacement actuator. The M800 when used in floating control mode (dip switch 2= On) requires 4 wires. The original actuator used 3 wires to provide floating control.

Issue What is the unit load of a TC900 thermostat and what are the bias and termination requirements when used with a SmartX Server. Product Line EcoStruxure Building Operation, Field Devices Environment TC907-3A4LMA TC907-3A4DLMSA TC907-4FMSA TC907-3A4DPMSA TC907-3A4DPMSA-24 TC903-3A4LMA TC903-3A4DLMSA TC903-4FMSA TC903-3A4DPMSA TC903-3A4DPMSA-24 SmartX Server Cause Documentation does not state the RS-485 transceiver type for the TC900 range, making it unclear how many devices can exist under a SmartX servers RS-485 serial port ComA or ComB. Resolution Use the Worksheet for Configuration of RS-485 Bus with generic RS-485 devices on Webhelp to determine the appropriate Modbus configuration. The answers to the transceiver interface attributes below can be applied to complete the worksheet. Q1 Failsafe Receiver : The TC900 uses an RS-485 transceiver with an integrated idle-state failsafe receiver. Q2 Data Transmission Speed : TC900 thermostats can be configured to communicate at 4800, 9600, 19200 or 38400 bps. Q4 Isolated Interface : The TC900 does not provide an isolated RS-485 interface. Q6a Measured Resistance : With no electrical connections to the TC900, the measured resistance between the RS-485 low-side (-) signal and the communications common is 8.2K ohms. Based on this the unit load of the TC900 is 1.46 (12.000/8,200) Bias requirements and number of devices If there are only TC900 devices on the RS-485 bus then Generic RS-485 Network Device configuration 1 applies, configuration becomes very simple and no node or distance reductions are called for. The failsafe receivers can typically operate with no added bias resistors. Connect a 120 ohm termination resistor across the + and - data lines at the head end of the bus (typically at the SmartX server). Connect another 120 ohm termination resistor across the + and - data lines on the last node at the far end of the bus. Connect the shield drain wire to earth ground terminal rail in the panel with the SmartX server. This is the only ground connection of the shield for the complete cable segment. Connect the RET/Shield terminal (see the figure below) on the SmartX server to the ground rail in the panel using a 12 AWG (3.31 mm²) to 18 AWG (0.82 mm²) wire. Since the TC900 has a unit load of 1.4 the maximum number of devices that can be placed under each comm port using this configuration is 21 (31.5 / 1.46 = 21.5) Also check out the SmartStruxure-RS485-Controller Unit Load Quick-Help video on the Exchange.
