ICP DAS DNP-211 DNP3 Master to Modbus TCP Server gateway

The ICP DAS DNP-211 is a DNP3 Master to Modbus TCP Server gateway. It provides protocol translation between the DNP3 and Modbus TCP protocols. It can connect an existed SCADA DNP3 network with an Ethernet-based master device as long as this master device supports the Modbus TCP protocol.

For the DNP3 network, the DNP-211 is a DNP3 master device, supporting Data Groups 1, 10, 12, 20, 30, 40 and 41. From the view of the Modbus TCP network, DNP-211 plays a Modbus TCP server role, supporting Function Codes 1, 2, 3, 4, 15 and 16. It can receive the commands from the Modbus TCP client and process the commands to reply or send the related DNP3 data. All the DNP3 I/O data and Modbus address mapping can be configured via the DNP-211 utility.

The DNP-211 supports up to 32 DNP3 outstations, and up to 16 Modbus client connections.
