Introduction
The GRP-540M-NB provided by ICP DAS is a NB-IoT gateway for Ethernet and serial port. It can be used in M2M application fields to transfer the remote I/O or Modbus data via NB-IoT. Within the high performance CPU, the GRP-540M-NB can handle a large of data and are suited for the hard industrial environment. When connecting with NB-DA Server or MQTT Broker, the user can also control the devices which connected to GRP-540M-NB from the remote control center.
Application
- Data Collection and Remote Control (with NB-DA Server)
- Data Collection and Remote Control (with MQTT Broker)
