Gateway

DF1725IED-G is a modular and scalable automation system that can be configured and tailored for various applications and needs. This chapter gives an overview of the main functionalities.

Remote communication

The remote communication is used to connect a DF1725IED-G to upper level systems, such as Network Control Systems, Control Centers. The most common protocols, such as IEC 60870-5-101/104, DNP 3.0, are supported.

Communication gateway

The communication gateway functionality provides a gateway between process devices and upper level systems (NCC). The main tasks of the gateway are signal rerouting

and protocol conversions. DF1725IED-G also supports signal grouping and possibility to introduce custom mapping logic in the gateway engine.

Configurable communication lines function

No protocol is bound to any communication line, this means three things: the 1st is, any protocol can use any communication lines; the 2nd is, running instance number of one same protocol is unlimited, provide that there are adequate communication lines; the last is, besides some special protocols, any protocol can use any type communication medias.

Process communication

The process communication is used to connect various process devices, such as IEDs, RTU I/O Modules, BCUs, PLC, and Meters to a DF1725IED-G. A large selection of communication protocols and interfaces, such as IEC 61850, IEC 60870-5-10x, DNP

3.0 and Modbus  are supported. See Section 5.2.1 Communication protocols for the full list of supported protocols.

The process communication is used to retrieve data from the connected devices, such as status indications, events, and analog values, as well as to write data to the devices, such as commands, set points, and parameters. The data retrieved through the process communication can be archived, presented on the HMI, or forwarded to other systems.
