without interruption before an error or notice message is generated.
Depending on the setting and the type of error, this suppression acts on the:
•Display
• Current output
• Pulse/status output
User input:
0 to 100 s (in steps of one second)
Factory setting:
0 s
"
Caution!
If this function is activated error and notice messages are delayed by the time
corresponding to the setting before being forwarded to the higher-order controller (process
controller, etc.). It is therefore imperative to check in advance in order to make sure
whether a delay of this nature could affect the safety requirements of the process.
If error and notice messages cannot be suppressed, a value of 0 seconds must be entered
here.

RESTART SYSTEM (restart without interrupting power supply)
