Being able to communicate with an EZIO2X4 but not the EZX10RF indicates a communication problem or an address issue. Make sure the Insteon address is correct (no finger checks 8’s for B’s, etc). If the Insteon address is correct move the EZX10RF to the plug point of the PLC. Could be a phase coupling problem where the EZIO2X4 is on the same 120V leg as the PLC and the EZX10RF is on the opposite 120V leg.
