The Cellular IoT Modbus RTU can be used to remote PLC via RS485 or Ethernet port, converting Modbus RTU/Modbus TCP to SMS or cloud platform over ethernet or cellular networks.
The Cellular IoT Modbus RT
U inbuilt TCP/IP protocol stack make it suitable for internet of things (IoT) applications, it can be easily to operate by the provided cloud, app, and web server, or integrated to you IoT applications according to Ethernet or the TCP/UDP protocol, or integrated to SCADA systems by standard Modbus TCP protocol, too. This is very useful if you need remote control onsite devices with low cost solution.
Cellular IoT Modbus RTU专为恶劣的工业应用环境而设计，广泛应用于各种工业自动化、安防监控系统、自动测控系统、BTS监控、远程数据采集、遥测系统、自动控制系统。可用作远程开关、远程I/O、远程智能PLC、定时开关。
Cellular IoT Modbus RTU可作为BTS监控的远程访问控制，授权用户可以在指定时间免费打开门或打开机器，这有助于日常维护，节省传统授权的时间.
蜂窝物联网 Modbus RTU 支持 2 个 RS485 透明数据传输，并通过 GPRS/3G/4G/NB-IoT 网络和 RS485 串口作为 Modbus Slave 执行。此外，蜂窝物联网 Modbus RTU 可作为 Modbus RTU Master 读取智能电表、I/O 模块、PLC，并在触发阈值后转换为 SMS 警报，或通过 GPRS/3G/4G/ 将数据传输到远程服务器NB-IOT 网络。2个RS485接口可以一个作为Modbus RTU Master，另一个作为Slave。
