Can the ULP and modbus terminals on a BCM be used at the same time?

Product Line:
Powerpact P, R, and Masterpact breakers with communications

Resolution:
When ULP terminals of BCM are connected to anything but the FDM121, the modbus terminals are disabled.  With that exception, you can use the modbus terminals or the ULP terminals; not both.
For reference, the 2-wire modbus terminals are E3 and E4; the ULP terminals are E5 and E6.
