unable to control the breaker. Open/Close while it is possible to see the breaker status and read the measurements through the FDM
Following steps should be verified:
1-confirm that the register 670 (Auto/Manu) is = 1 (Auto),to be able to control te breaker (Open / Close)
2-As the BCM ULP firmware is 4.0.7 , read the register 660 where the FDM “Local – Remote” status is stored. If the register 660 is “1”, the FDM status is “Local” and you can only control the breaker from a FDM module, not from a remote Modbus device.
3- In order to connect a FDM module to the BCM ULP, you ,have to set the communication wiring as 2W+ULP.
