1.9 Information Interfaces
Information is exchanged through the local control panel, the PC interface, or two
optional communication interfaces (channel 1 and channel 2).
Using the first channel of the communication interfaces (COMM1), the P631 can
be wired either to the substation control system or to a telecontrol system. This
channel is optionally available with a switchable protocol (per IEC 60870‑5‑103,
IEC 870‑5‑101, DNP 3.0, MODBUS or Courier).
The second communication interface (COMM2, communication protocol per
IEC 60870‑5‑103 only) is designed for remote control.
As an order option, there is an Ethernet interface for communication per
IEC 61850 available instead of channel 1.
External clock synchronization can be accomplished via one of the
communication protocols or by using the optional IRIG‑B input.
