A DNP3 server protocol instance is activated if the function block instance is added
to the application configuration. The setting
Operation should be "On" and setting
Port should have the communication interface assignment.
The
STATUS
output of the function block is active if DNP3 client requests or DNP3
supervision messages have been received on the communication interface within an
interval defined by the link keep-alive parameter.
By default no DNP3 data is mapped to the protocol interface. Protocol data has to
be created using Communication Management in PCM600. There are two mapping
sets, “Mapping 1” and “Mapping 2”, and either can be used. Setting parameter
Mapping selection points to the mapping set used. Several DNP3 protocol instances
can point to the same mapping set.
For more information on the DNP3 server protocol, see the DNP3 communication
protocol manual.

3.2.15.2 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.
