Yes, the HMC/MLC can be configured as a Modbus TCP Master on COM3 and still retain the default Modbus TCP Slave configuration.

| You must
choose one or the other between master and slave for Modbus RTU, but Modbus
TCP can be both simultaneously thanks to Ethernet. As a master (client) you can read Modbus data from, or write Modbus data to, other Modbus TCP devices. |
