The PLC controller is S275 from www.gsm-m2m.com. it builts GSM GPRS and 3G Module, it can check the additional register's value automatically, if the value exceeds the threshold value, can send out sms to upto 10 users immediately. This unit equipped RS232/RS485 port, and ethernet port, also, as it claim in the specification, it supports both modbus rtu master and modbus slave.
