GSM-PRO2 series communication modules from Conta-Clip feature a Modbus RTU interface that enables easy data exchange with other controllers.
The 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. The GSM-PRO-CON extension module makes wiring even simpler. Plugged into the GSM-PRO2 module, it offers front-access terminals for connection to the controller.
The GSM-PRO2 parameterization software can be programmed to send a text or email fault message to specified recipients when the status of the PLC input changes.
Prompted by a text message that is sent to the GSM-PRO2 module, data is written into the PLC's digital and analog registers via the Modbus RTU interface. The PLC, acting as a master, reads out the data in order to trigger the corresponding actions. Various communication modules with and without GPS functionality are available for all common wireless standards up to 4G.
