CAUTION: The number of configuration data specified by the scanner when opening the implicit
communication must be even!
If configuration data exists when opening communication, then these are used for the following
purposes or checks:
The Output Value Hold Time specifies the minimum hold (wait) time in milliseconds for the events
below until the outputs are switched from the last valid values to the failsafe state (delay connection
timeout).
The Output Hold Time is set to a default value (1000 ms) after resetting the device and after the last
close of an implicit connection.
Start conditions for the Output Hold Time are:
-
Any kind of EIP communication problem
-
Heartbeat counter frozen for at least 200 ms
The Output Hold Timer is immediately reset once all triggering events have disappeared.
CAUTION: The shortest period for the Output Hold Time is 10 ms!
The list of IDs of the DIOLINE20 substations is used to check the following circumstances:
-
Are all specified modules actually physically attached to the L-Bus?
-
Do the physically-connected modules exist in the same order?
CAUTION: If there are discrepancies, then no implicit communication connection is opened!
