See the below example using the SE8650 UO11 terminal  

Issue The Device ID and name in a BACnet SE7000 room controller is factory set to the model number plus the MAC address. By default the MAC is set to 254 in the room controller, meaning the device does not communicate since valid MAC addresses need to be in the range 0-127. In cases where multiple BACnet networks containing SE7000 BACnet room controllers are connected to the same BACnet internetwork there could be duplicate ID's when using this schema. In these instances a T7600 Device Configurator Tool can be used to change these fields. Product Line EcoStruxure Building Operation, EcoStruxure Building Expert Environment • Building Operation Workstation • Building Operation Automation Server • SSL SE7000 Cause The Device ID and name in a BACnet SE7000 room controller is factory set to the model number plus the MAC address. By default the MAC is set to 254 in the room controller, meaning the device does not communicate since valid MAC addresses need to be in the range 0-127. For example when a VT7200F5000B room controller with a MAC address of 41 is connected to a network, its default Device Name will be VT7200F5x00B-41 and its default Device ID will be 72041. The device ID and name will change as soon as the MAC address is changed at the controller. The MAC address is set in the Installer configuration parameter menu using the Com Addr parameter. These fields can also be set by any BACnet management tool that can access these properties. Resolution The goal of this document is to give simple instructions on how to change the Device Instance of the VT7000 series thermostats using the T7600 Device Configurator tool and the recommended connections and wiring. 1. Converter (can be other models): Model 485OT9Lor USOTL4 from B&B Electronics. A USB-to-RS485 converter, like one used for MSTP captures, will work as well.  2. Recommended wiring for the configuration of Device Instances: The SE7000 room controllers have to be connected only to the converter (which has to be powered up) and disconnected from the network controller. The EOL resistors should remain at both ends of the trunk. 3. Setting up the software The software is supplied as a simple installer file download the software from here and run the installer. Prior to running the program for the first time setup steps 4 and 5 must to be accomplished. 4. Setting Windows Compatibility mode The T7600 Device Configurator Tool is legacy tool and therefore is only supported in a Windows 9X operating system, It has been tested and found to work in later versions of Windows by setting the compatibility mode to Windows 95 Locate the executable file T7600_MSTP_Config.exe in the C:\Program Files\Fastek\T7600 Config\ folder. Right click the file and select properties Go to the compatibility tab and change select Run this program in compatibility mode for: "Windows 95" from the drop down menu then click OK 5. Set the PC communications port Open the BACDOCM.ini located in the C:\Windows folder and enter communications port number in the line highlighted below and save the file. If a valid com port is not entered here the program will generate errors when launched and will not operate. Instructions on how to use the converter (file T7x00 MSTP Config.exe): 1. Open the configuration Tool 2. Double click on the BACDOOR icon in the icon tray on the bottom right of the PC. 3. On the window BACDOOR OEM MSTP Client status, click configure and in the configuration window set the Device instance to any number that does not conflict with any other device instance on the network.: 4. Close the BACDOOR configuration window and in the T7000 Device Configurator, click refresh device list. 6. All the devices on the trunk should appear and you can start changing the device instances one after the other. To do that: a. A- Select the first device.     B- Click Connect to device. The connection process can be long, wait for all the objects to be discovered.     C- change the instance ID using the keyboard.     D- click Apply changes. b. Select the next device and do the same. c. Repeat this action for all the discovered devices. 7. After making all the recommended changes, remove the RS-485 to 232 converter and reconnect the network.

Issue The SE7000 Series controller will not bind to a MPM controller with Building Expert version 2.7. SE7000 controller is not listed in the discovery window when a bind is performed.  Product Line EcoStruxure Building Operation, EcoStruxure Building Expert Environment Building Operation Workstation Building Operation Automation Server SSL SE7000 SSL MPM Cause It was determined that the SE7000 controller had the old Zigbee module installed. Starting with Building Expert 2.7, the SE7000 Series stats requires the newer Zigbee Pro module in order to connect to the MPM controller. You can determine if the new module is installed by the part number printed on the Zigbee module. The old Zigbee module has a label with the part number 051-0125R01 printed in it. Resolution The older Zigbee module will have to be replaced with the new Zigbee Pro module, and can be field replaced. The newer Zigbee Pro module can be ordered using part number VCM7000V5045P. The actual part number that will appear on the new Zigbee Pro module label is 051-0132R00.  The module is the smaller PCB board mounted on the left side of the main PCB board.  1. Remove the SE7000 controller’s cover.  2. Carefully remove the Zigbee module form the main board.     * The main PCB board is hinged on the left and is held in place by two tabs on the right      * Gently press the tabs to the right to release the main PCB board and swing it open      * Gently depress the 2 plastic mounts that hold the Zigbee module to the main PCB board     * Remove the Zigbee module being careful not to damage the connection pins. 3. Replace with the new Zigbee module (051-0132R00) 4. Replace the cover. 5. Configure the Zigbee network of the SE7000 controller  You should now be able to discover the SE7000 controller in the MPM.

Issue Strange characters are displayed in the display of a VT7000 and SE7000 Series thermostat. Product Line EcoStruxure Building Operation, EcoStruxure Building Expert Environment Building Operation Workstation Building Operation Automation Server SSL SE7000 Cause The thermostat has experienced a brownout condition. Any time the power drops below 16-17Vac for a 1/10 of a second or so it will cause this condition. Resolution The thermostat still updates to the BMS correctly; it’s only its display that’s affected.  Cycling power to the unit will clear the issue. However, if the brown out condition is not addressed, it can happen again. If a repeated brownout issue at the site cannot be corrected, consider powering the controller with an UPS.   

Issue Sometimes, switching 230V with the SE7000 controller is requested and/or necessary, but no such product is listed in the current portfolio. Product Line EcoStruxure Building Operation, EcoStruxure Building Expert Environment • Building Operation Workstation • Building Operation Automation Server • SSL SE7000 Cause No product that matches the requests are currently listed in the portfolio Resolution Two relay boards for fan coil units will be released late 2012.  These will allow the SE7000 devices to be used with 230V systems.

Issue Some controllers in the SE7000 range and all of the current SE8000 range cannot be supplied with a LON interface. Product Line EcoStruxure Building Operation, EcoStruxure Building Expert Environment Building Operation Workstation Building Operation Automation Server SSL SE7000 Cause Some controllers in the SE7000 range (e.g SE7600E) are not shown with a part number for a factory-fitted LON interface in the Schneider Electric documentation.  Although they can be supplied in a 'network ready' version and there is a part number for a separate LON interface listed, the two are not compatible.  There is no LON network interface for the SE8000 range. Resolution Only the controllers currently available with a LON interface as per the Schneider Electric documentation are available to communicate with a LON system. There are no plans to add a LON card option to the other SE7000 series controllers or any of the SE8000 range and they cannot be fitted separately.   The only communication options for these controllers is BACnet or Zigbee.

Issue Connecting a 4-20mA sensor to an analog input on the MPM Product Line EcoStruxure Building Expert Environment Multi Purpose Manager (MPM) Cause "Input Type" for an Analog Input can only be set to either "Volts" or Ohms" Resolution A shunt resistor is required to be installed across the input and ground terminals on the MPM in order to be able to measure the voltage drop over the resistor (see image below). An AIC object is then used to convert the voltage readings to mA reading. Set up AI and AIC as shown in the images below Note: The shunt resistor needs to be a precision resistor of 0.05 % and needs to be mounted as close as possible to the data acquisition system. Preferably directly screwed into the differential inputs, otherwise, you will measure the voltage over the resistor minus the voltage drop of the additional cable which affects the accuracy of your measurement.
