Configuration
4.10 Partner stations
CP 1243-8 IRC
94 Operating Instructions, 02/2018, C79000-G8976-C385-03
●
If the CP does not receive a sign of life from the communications partner within the
configured time, the CP interprets this as a fault/error on the partner. The CP aborts the
connection and attempts to re-establish it.
If you enter 0, the function is deactivated.

Indicates the DNP3 implementation level supported by the CP
In the DNP3 specification, various levels of protocol conformity are and they describe the
supported range of functions (subset) of a master or a station. These DNP3
implementation levels (implementation levels) are referred to as "DNP3 Application Layer
protocol Level" and abbreviated with DNP3-L1 to DNP3-L4.
For the communication between the CP and the master, the DNP3 level supported by the
master must be known.
The selection of the level used by the DNP3 CP which must correspond to that of the
connected master is set separately in STEP 7 for each individual communications partner
(DNP3 master).
The CP supports the following DNP3 implementation levels:
– Level 1
– Level 2
– Level 3
– Level 4
– Level 4+
The DNP3 implementation level known here as Level 4+ that is not specified in the
standard contains the range of functions of Level 4 and in addition support of the
following DNP3 data types / variations:
– 64-bit analog value as floating-point number without time of day
– 64-bit analog value as floating-point number with time of day
– Counter event with time of day in 16-bit format
– Counter event with time of day in 32-bit format
●
Mode with which DNP events are transferred to this communications partner:
– Chronological transfer of individual frames
or
– Transfer of collected frames per data point as a block.
