The MDC-211-433 is a Modbus data concentrator developed by ICP DAS. It features Ethernet, 433MHz wireless communication, RS-232 and RS-485 communication interfaces, enabling Modbus RTU devices to connect to an Ethernet network. Based on a user-defined command list, the MDC-211-433 reads the data from Modbus RTU devices in sequences and integrates the data of different Modbus RTU devices into a continuous address format. This allows a remote monitoring host to access data from multiple Modbus RTU devices simultaneously via Ethernet.
By leveraging the MDC-211-433’s Modbus data centralized management function and the convenience of Ethernet communication, users can quickly build a stable remote monitoring system. This significantly simplifies data acquisition while reducing Ethernet traffic and improving overall system performance.
