Scenario
PGM network is down
Values that can be configured as user-defined values
Attention
When configuring the initialization values for each channel, you must ensure that the failsafe mode parameter value
and the Init Value parameter value match with each other.
For example, if you have set the failsafe mode parameter as max value, then you must define the initial value for that
specific channel (100 for AO channel and 1 for DO channel).
The following figure displays a portion of the Parameters page of a device and IOM Configuration/PDC page of a
DSB.
The following table summarizes the various user-defined values that you can define for the output channels to
re-initialize after recovering from the communication break scenarios.
Output channel re-initialization description
If the Connection Break Timeout applicable for
Network Down check box is selected, the output channels
initialize back from the user-defined values after the
connection break timeout timer is exceeded.
If the Connection Break Timeout applicable for
Network Down check box is not selected, the output
channels initialize back from the user-defined values
immediately.
Attention
The Connection Break Timeout applicable for
Network Down check box is added on the Main tab of
the DSB configuration form. This check box is available
from Experion R410.2 and later.
