CONTA-CLIP Direct Modbus Connection to PLCs
CONTA-CLIP has developed a compact communication module that features a Modbus RTU (RS485) interface for easy data exchange with with other controllers like a PLC. The GSM-PRO2 series communication modules operate in slave mode and can, for example, provide a PLC with added GSM functionality via an easy plug connection to the RS485 port directly on the C-type mounting rail.
