Issue A third party BACnet system is able to host  values from a SmartStruxure Lite MPM but an MPM does not seem able to host values from another BACnet system or device. Environment BACnet MPM-VA MPM-UN MPM-GW Cause SmartStruxure Lite Managers have full BACnet server capabilities, however BACnet client functionality is not native to the MPM and is currently only available through Lua programming. Resolution Integrating SmartStruxure Lite™ Managers with third-party BACnet server devices requires a BACnet client script. A sample script (download here) can be used to perform read and write operations to other devices via BACnet IP, however, a few tips and limitations must be taken into consideration before deployment on site. NOTE1: The delay at the beginning of the script (if scl.sysclock() > 90 then) must not be removed or modified. Otherwise, the MPM will keep rebooting endlessly and would require restoring its factory defaults before gaining access to Building Expert again. NOTE2 : The more points used in the script, The higher the MPMs CPU% Usage will be and the less responsive the MPM will be. Therefore, it is recommended to only read/write the necessary points and not all the points on the third party devices. Also, if some points are more important that others, the polling time can be increased to 60 seconds for example.   NOTE3: The more objects you have on the MPM, the less room you have for BACnet points. PGs, Trends and Events consume a substantial amount of CPU Usage so it is important to keep an eye on it as you add more points in the script.   NOTE4 : Run the script every 5 seconds or more if possible   Limitations: - Reading/Writing to Multi State Values (MSV) is not supported

Issue Simple Modbus Lua Script Product Line EcoStruxure Building Expert Environment Lua Programming Cause Simple script to test Modbus function Resolution In each of the samples, the following needs to be observed: The Modbus port is closed and opened with the port settings. The samples can be combined but the port is only set once. The settings for the Modbus RS485 port requires an address, in this instance 99 is used. This must be different from the slaves. The nnn.MOD1 must be left unchecked so that it is not enabled. This will allow the Lua script ModbusB to work. For added functionality the "Print" command is used. The "print" command provides added functionality indicating a successful read / write in the output window. If the result = 0 then the read / write is successful. Anything else is an error code. Contact Product Support. The value = is the value that is either read in or written dependant on the function used. The following samples provide simple read / write functions.: Coil Registers Digital Input Registers Holding Registers Input Registers 32bit Floating Point

Issue A space temperature sensor is not reading correctly on a MicroSmart controller (Model # MSC-P-1504).  The type of sensor is not known due to its remote location.  What are the possible values for the SCALE, OFSET, and CVTYP elements? Environment MicroSmart MSC-P-1500 line of controllers Cause Trying to determine the type of sensor installed so a spare sensor can be brought for the service call.
