GSM-PRO2 series communication modules feature a Modbus RTU (RS-485) interface that enables easy data exchange with other controllers. The modules operate in slave mode and can provide a PLC with added GSM functionality via a plug connection to the RS-485 port directly on the C-type mounting rail. The GSM-PRO-CON extension module makes wiring even simpler. Plugged into the module, it offers front-access terminals for connection to the controller. Parameterization software can be programmed to send a text or e-mail fault message to specified recipients when the status of the PLC input changes.
