This communication mode uses the MEWTOCOL-COM or Modbus RTU protocol to exchange data between a master and one or more slaves. This is called 1:1 or 1:N communication. The side that issues commands is called master. The slave receives the commands, executes the process and sends back responses. The slave answers automatically to the commands received from the master, so no program is necessary on the slave.
The MEWTOCOL-COM master function is not supported by all PLCs.
