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 When proportional 0-10Vdc type valve actuators are used with a SE8000 room controller, the actuators behavior is inconsistent. Environment SE8300 SE8350 SE8600 SE8600 Cause Some valve actuators e.g. wax filled (thermic type) have a high input impedance e.g. 100 Kohms. When connected to a SE8000 room controller, the actuators operation may be sluggish or may never operate. The SE8000 has a maximum output of 5mA when set to proportional control, using actuators with high impedance, the SE8000 room controller fails to recognise there is an actuator and does not drive it. Resolution A burden resistor can be fitted to draw some current from the SE8000 room controller because the actuator's impedance is too large. The burden resistor needs to be large enough not to affect normal use, but small enough to draw a current from the SE8000 room controller. Using ohms law: Valve actuator @ 100 Kohm SE8000 UO output is 5 mA, maximum Vdc output is 10 Vdc. Minimum size of burden resistor: 10 Vdc/5 mA = 2 Kohm. It may be necessary to increase the size of the burden resistor e.g. 10Kohm. The burden resistor is then installed between the signal ground and the signal, either at the controller or the actuator end. Test the actuators for correct operation.

Issue Accuracy of values/input values displayed using a MPM Product Line EcoStruxure Building Expert Environment SmartStruxure Lite using MPM Cause Number of decimal places is 12.345 when the site would prefer 12.3 or 12.34. Resolution You may want to use this example in a running program (PGx) and replace ME.AVx by appropriate variable. Example Program: ME.AVx = math.floor(ME.AVx * 100 + 0.5) / 100 Below is a screenshot of AV3 2.234 value displayed correctly in AV4 as 2.23

Issue The Windows power save is interrupting system operation, i.e if you have a graphic open on a Workstation which is talking to another PC and the mouse has been inactive for some time, when you move the mouse it takes some time to update the graphics Environment Windows ES Continuum Inet Vista SmartStruxure SmartStruxure Lite SBO Cause This is caused by the Windows OS going into a power save mode, this will normally close down the CPU, Network adapter, graphics card etc Resolution   PC is going into a power save mode, Go into, "Control panel", make sure view is "Small icons", then click "Power Options" in here you will have a number of option, set this to "High performance" then "change plan settings" make sure all are set to Never or high performance, when you have done this, goto "Network and Internet" then "Change adapter settings", right click on your network adapter and goto "properties" then click "Configure" then "Power Management" make sure that the power save settings are off, this will stop the network from going to sleep.   This will need to be done on the ES, Workstation PC, Continuum Workstation, SQL server, etc This should then stop you having the delay as the PC wakes up

Issue Does SmartStruxure Lite support GPRS? Environment SmartStruxure LIte Cause End customer request Resolution GPRS has not been tested.  3G is recommended over GPRS. The 3G cradlepoint solution was tested and is currently implemented on a project. However, it was not tested with all phone providers and is not supported.

Issue DHCP for MPMs Environment StruxureWare Lite site with MPM Cause Can DHCP be used for network settings or does the IP address need to be static Resolution The MPM's do not support DHCP, only static IP addressing. It is planned to have DHCP on the new MPM platform that is in development. There are no dates or firm roadmaps available, but DHCP is one of the desired features of that new product line. The DHCP support is planned in the future generation of controllers which means a completely new hardware platform. This would not be a firmware upgrade on the current generation of products. To get to the IP address settings,  Then input the static IP address for the MPM

Issue The MPM-UN controller comes with 100 AV's and 100 BV's. These may be added to the current database of the controller for various programming needs. However, when SE7000 controllers are added, they consume 14 of these AV's each (this is with the 2.5.6 firmware, which limits the ZigBee window to 14 AV points). The AV points are quickly gone from the MPM stock, and once 100 AV's are used, there are no more for further programming. If programming is done first, this is no problem, because the addition of SE7000 devices will continue to consume the remaining AV's from the original 100 available, then create AV's over 100 once the original are gone. How many AV's are available until the controller just doesn't recognize them, or stops allocating them to additional SE7000 controllers? Environment MPM-VA MPM-UN MPM-GW Cause As standard the library of objects in Building Expert displays 100 AV and 100 BV objects, however more are available but it is not clear how to access them. Resolution An MPM has capacity for up to 700 AV's and 700 BV's. Once the initial 100 are consumed, you can add Value Banks of 100 each AV and BV. Value Banks are added as devices and will be listed as sub devices under the main MPM. To add a Value Bank: 1. In the Building Expert Explorer panel, select the Add Devices icon . A new window opens. 2. Select Value Bank to add this your Controller. Added Device shows in Device to add column. 3. Click Add Devices button. 4. Repeat steps 2 - 3 to add any additional Devices. 5. Click Close

Issue How can objects of a SmartStruxure™ Lite network be made available as BACnet points to third party BACnet building management system (BMS)? Product Line EcoStruxure Building Operation Environment SmartStruxure Lite BACnet Cause The BACnet protocol is always active, as long as the network cable is connected. However, two different BACnet options can be selected: IP or Ethernet. The default option is Ethernet and this will need to be changed if BACnet over IP is required. Resolution The BACnet protocol is always active, as long as the network cable is connected. However, two different BACnet options can be selected: IP or Ethernet. The default option is Ethernet. To verify or to change which BACnet protocol is currently in use, select the SmartStruxure Lite Manager that you want to configure from the left-side Network panel. Then choose the BACnet configuration list item. Define the Network Number (if the protocol selected is BACnet IP). Note: The Network number must be defined only on the monitor Manager. It shall be different then the Parent Network where the monitor is connected. A BACnet Device is uniquely located by a network number and a MAC address. Creating two or more B/IP networks, each with a unique network number, can be useful for limiting the propagation of local broadcast messages and for providing security by confining traffic to a particular geographic or logical area. Select the desired protocol type from the drop-down list between BACnet IP and BACnet Ethernet. Then choose an optional port number (if the protocol selected is BACnet IP). Default is 47808. Select the BACnet Priority of the BACnet write action of the SmartStruxure™ Lite's network monitor. Default is 10. Note: SmartStruxure™ Lite does not support BACnet Write Priority, per se. However, in Firmware version 2.4.x and newer, it is possible to assign the write priority for all SmartStruxure™ Lite BACnet points. Default value is 10, except if you upgrade a Manager using a version 2.3.x or older, BACnet priority will be 8, but can be changed. Click the Save button to apply the configuration changes. Click hit the Save All button to make the modifications permanent and reboot the Manager for the new options to enter into effect. Change the BACnet instance number of the Manager if required. IMPORTANT Each Manager must have a unique BACnet device instance number. A Manager device instance number can be changed by selecting the top-left icon inside the left-side Network panel.
