Issue I have package units with point count that exceeds the SE78600 capacity, can I simply add the SEC-TE in order to complete I/O points requirements? Environment SEC_TE MPM SE8600 Cause Unfortunately, the SEC– TE can’t be used as extended I/O modules with the SE8600 however; you may use SEC-TE with the MPM-UN. Resolution SEC – TE can not communicate directly with the SE8600. However you can use the SEC-TE with the MPM-UN.

Issue Having issues configuring the pulse counter on the SEC-TE (TE2) Environment SmartStruxure Lite Multi-Purpose Manager SEC-TE (TE2) Cause N/A Resolution Navigate to the ZVC object of the SEC-TE and change "Analog Input 3 Mode" to "pulse counting". The value in AI3 (the counter) will then be incremented every time the pulse goes from 1 to 0 regardless of how long that takes. However, to convert the value of the counter to a more meaningful reading (e.g. water flow), you would need to use a Lua script in the MPM.   To reset the counter, click on the "Reset" button   Possible issues while testing: Using the Binary outputs of the TE2 for testing purposes will cause the counter to display unreliable readings. In fact, any binary output that induces voltage in AI3 will in inaccurate readings due to the noise induced. Instead, The binary outputs of the MPM can be used for testing before deploying the equipment on site.

Issue Daylight savings do not take effect when it starts on 4th October Environment Multi Purpose Manager 2.15 and 2.16.    Cause Australia starts DST in October and ends in April of the following year. In North America and Europe, DST starts In March and ends in October or November in the same year. The built in DST feature in the MPM assumes that the "DST_Start_month" must be before the "DST_End_Month".  This issue will also applies to countries where the start of DST is towards the end of the year and DST ends the following year.  Resolution This issue has been reported to R&D. The following workaround can be used before this issue is fixed in a future MPM firmware.  1. Configure DST in the MPM to start in April and set DST to end in October. 2. Set the DST offset to -1 hour using the following Lua script in the MPM (add a Lua object and enter the following code)         if not init then            ME.CFG1_Time_Dst_Offset.value = -3600            init = 1         end     if not init then ME.CFG1_Time_Dst_Offset.value = -3600 init = 1 end

Issue It is required to know the IP rating on the SE7000 and SE8000 range devices, but this is not written in the datasheet. Product Line EcoStruxure Building Expert Environment SE7000 SE8000 Cause The information was not available at the time where the datasheets were created. Resolution The IP rating on the devices is IP30. At the time of writing, tests are ongoing for IP31 rating.

Issue When Forcing a value from SBO, it is just overwritten by the Lua script all the time. Product Line EcoStruxure Building Expert Environment MPM SE8000 Cause By default, the MPM executes the program once every second, so if written simply like: Output_1 = Off the output will be turned Off every second. Resolution Declare a few variables in the Lua script that will help you implement the logic you need, here is an example: var("Override_Status","ME.BV1") var("Override_Value","ME.BV2") if changed.Override_Status and Override_Status == 1 then ME.BO1 = Override_Value elseif changed.Override_Status and Override_Status == 0 then ME.BO1 = ME.BI1 end Basically, an override status points will act as a "Override button", and when it is active, The output will be equal to override value specified in SBO. Else, if it is disabled, the output will be set to what ever you currently have in your script. In the example above, the output will be equal to the input.

Resolution Disable or delete 1 by 1 your Lua PG's to identify the PG with the issue.

Issue Unable to turn the heat on SE7600X   Environment   SE7600 Cause Wiring issue or misconfiguration Resolution You may refer to the diagram below to avoid wiring mistakes. Do not forget  jumper J1 on terminals |RC |RH|     Configuration Two important parameters to configure for heating.   Number of heating stages.  Default value = 2 stages When selected the device will revert the operation of 2 stages thermostat to single stage operation or to modulating 0 to 10Vdc heating output: 0 = 0-10Vdc analog heating output (AO) 1 = 1 heating stage (W1) 2 = 2 heating stages (W1 & W2)   Fan control Default value = On When selecting on; the Terminal Equipment Controller in all cases will always control the fan (terminal G). Valid for On or Auto fan mode When selecting Off; the fan (terminal G), when heating stages (terminals W1 & W2) are solicited, will not be energized. The fan in this case will be controlled by the equipment fan limit control. Valid only for Auto fan mode.   On fan mode will leave the fan always on. For multistage models, fan control applies to W1 & W2 For heat pump models, fan control applies to W1 only (Emergency heat)

Issue How is a subnet defined? Environment Refer to "TCP/IP Network Administration" by Craig Hunt, O’Reilly & Associates, Inc. Cause Sectioning network communication by subnets. Resolution A subnet is defined by applying a bit mask (subnet mask) to the IP address. If a bit is on in the mask, that equivalent bit in the address is interpreted as a network bit. If a bit in the mask is off, the bit belongs to the host part of the address. The subnet is only known locally.
