AutoLog® GSM Modbus Gateway
GSM ↔ Modbus bridge · Built-in GSM/GPRS modem · No on-board I/O
GSM-GW is a PLC designed exclusively for communication. It does not carry on-board digital or analog I/O; instead it acts as a programmable bridge between Modbus equipment and the GSM network. Built-in GSM/GPRS modem and driver. Two serial ports — serial port 1 for GSM modem / programming, serial port 2 for Modbus RTU master/slave or, with plug-in modules, RS485, Modbus TCP, or an AutoLog Wireless I/O & Sensor master. Same AutoLog GsmProgrammer programming environment as the rest of the GSM-RTU family — full PLC logic, 32 PID controllers, FTP data logging, advanced SMS generation.
