General
AF-GSM is a new 4G remote wireless data acquisition device launched by Acrel Electric. By adopting embedded design, it is embedded TCP/IP protocol stack, as well as powerful microprocessor chip and built-in watchdog, therefore, it has reliable and stable performance.
Function
◆ It supports data acquisition of the serial port MODBUS RTU protocol and communicates with the Acrel server through the Acrel platform protocol.
◆ It supports for data acquisition of up to 30 MODBUS RTU devices.
◆ It supports the acquisition of 5 register address fields for each MODBUS device, with each register address range not exceeding 64.
◆ It supports triggering alarms by presetting alarm addresses and alarm values for each MODBUS address range. There are currently up to 14 alarm addresses for each address field.
◆ It supports server MODBUS or LORA unvarnished transmission communication.
◆ It supports to connect the data center by fixed IP and dynamic domain name resolution.
