The MPC-374 is a Modbus RTU to Modbus TCP gateway developed to communicate with the most common protocols such as M-Bus, Modbus TCP/IP, DATA/Req, IEC60870-5-104: 2000, and a special transparent mode for special manufacturer protocols, so almost any device can be connected.

It can also measure and store different kinds of discrete inputs (limit switches, push buttons, alarms, relay contacts..), discrete outputs (remote management) and analog inputs (current/voltage).

Stored data can be send to remote user through GSM/GPRS modem or Ethernet port (LAN/Internet) using open and standard protocol (Modbus gateway), greatly simplifying the systems integration into SCADA / user software.
