The DNP-211 CR bridges DNP3 field devices and Ethernet-based Modbus TCP masters. On the DNP3 side it acts as the master, reading from and writing to outstations over TCP, UDP or serial. On the Modbus side it is a server that accepts requests from Modbus TCP clients and either answers them directly or forwards the related DNP3 data.Mapping between DNP3 points and Modbus addresses is set up in the DNP-211 utility, so existing DNP3 networks can be exposed to a Modbus TCP host without rewiring the field devices. Outstation connection status is also available at a Modbus address, which helps supervisory logic detect a lost link.Capacity covers up to 32 DNP3 outstations and 16 Modbus TCP client connections, with 8192 digital I/O bits and 2048 channels each for counter and analogue points. It is a suitable choice where an engineer needs a compact DIN-rail gateway with a metal housing and a wide 12 to 48 VDC supply range.ApplicationsIntegrating DNP3 outstations, RTUs and IEDs with Modbus TCP master systemsSCADA communication in utilities such as electric and water companiesConnecting existing DNP3 networks to Ethernet-based Modbus TCP masters
