Yes you can interface PLC on GSM for sending SMS only.
Most of the PLC s communicate on Modbus. Use RS 232 interface with Modbus ASCII protocol.
You need to program the AT commands for the GSM modem with a mobile no programmed in the PLC.
This feature is an add-on SW that will have to be embedded in the PLC.

But you cannot correct a PLC program using GSM modem.
