selection points to the mapping set used. Several DNP3 protocol instances can point
to the same mapping set.

Functionality

The function block represents one IEC 60870-5-103 server protocol instance in the
protection relay. Function block settings include communication interface assignment
for the instance, that is, serial communication port 1 or 2.
An IEC 60870-5-103 server protocol instance is activated if the function block
instance is added to the application configuration. The setting Operation should be
"On" and setting Serial port should have the communication interface assignment.
The STATUS output of the function block is active if IEC 60870-5-103 client requests
have been received on the communication interface within 15 seconds.
The function block input EC_FRZ relates to possible ASDU 205 (mostly energy)
counters defined in the protection relay. Activation of the EC_FRZ input freezes and
captures the current ASDU 205 counter values and sends them to the IEC
60870-5-103 client. Several options for the activation exist.
1. EC_FRZ object exists as a control object in the IEC 60870-5-103 data model, and
can be written from the client.
2. EC_FRZ physical input can be activated from an internal or external timer
application signal.
By default most IEC 60870-5-103 data is pre-mapped to the protocol interface.
However, protocol data can be deleted, added and modified using Communication
Management in PCM600.

60870-5-103 communication protocol manual.
