The IC693CMM311 can only be a Modbus slave. When configured as a slave you don't need ay ladder logic to support Modbus communications. If you need the PLC to be a Modbus master, you will need the IC693CPU363 module which has a serial port. You could also do it with the HE693RTM705 (Modbus master) module from Horner Electric or the Programmable coprocessor module.
