AWT100 wireless communication terminal

General

At present, wireless technology has gradually become an important direction for the

development and application of networks in the industrial Internet in the future due to its

advantages of easy deployment, low construction cost and wide applicable environment.

AWT100 wireless communication terminal is a new wireless data acquisition device launched

by Acrel. The uplink communication includes 2G, 4G, NB, LoRa, LoRaWAN and other

communication modes. The downlink interface provides a standard RS485 data interface,

which can easily connect power meters and RTUs, PLC, industrial computers and other

equipment, only need to complete the initial configuration, you can complete the data

acquisition of MODBUS equipment; at the same time AWT100 series wireless communication

terminal uses a powerful micro-processing chip, with built-in watchdog technology, reliable

performance stable.

Acrel wireless communication terminal

Function Description

■Support data acquisition of serial port MODBUS RTU protocol, and communicate with Acrel

server through Acrel platform protocol.

■Supports data acquisition for up to 30 MODBUS RTU devices.

■Supports the acquisition of 5 register address fields for each MODBUS device, each register

address range does not exceed 64.

■ Supports triggering alarms by preset alarm addresses and alarm values for each MODBUS

address range. Each address domain alarm address currently has a maximum of five.

■Support server MODBUS or LoRa transparent communication.

■Support fixed IP and dynamic domain name resolution to connect to the data center.

■Support transparent transmission protocol, universal mode (active rotation, timed reporting),

MQTT protocol, smart power wireless protocol, prepaid wireless protocol

Negotiation, custom development.

■ The functions of the AWT100-LW wireless communication terminal are still under

development, and data can be uploaded to the server through LoRa communication in the

future.

Note: ①The AWT100-2G/NB/4G wireless communication terminal can communicate with the

Acrelserver through the Encore platform protocol.
