ICP DAS has developed an intelligent 4G gateway RTU-140, intended to create standalone M2M solutions on 3G/4G networks. The gateway is based on a high-performance 32-bit CPU and allows you to connect up to 3 Modbus RTU devices via RS-485.
The gateway automatically transmits data to the remote M2M RTU Center at a predetermined time interval. To build a remote control system for devices, ICP DAS offers several software tools: M2M RTU Center, Win32 API M2M RTU library and OPC server for connecting to SCADA.
The gateway also allows you to record I/O data and GPS signals to a Micro SD card. To prevent loss of efficiency of the gateway, you can install an external lithium battery.
The scheme of operation of the 4G gateway RTU-140 is shown in the picture.
RTU-140 software:
- M2M RTU Center.
- M2M RTU API.
- NAPOPC.M2M DA Server. NAPOPC.M2M DA Server is an OPC server that allows you to connect M2M gateways to SCADA systems via the OPC 2.0 protocol
- Ez Data Logger. EZ Data Logger software allows you to create a small data collection system even without any programming skills and to display parameters on a screen in a convenient format
RTU-140 gateway can be used to build transport solutions or stationary measuring systems.
