Siemens SIMATIC HMI series System Manual

General
If option "Call On Time for each Action" is activated, a time measurement is performed for
every action that is executed and is output with standard function "On Time".
Example
Check
If checkbox
"Check wich Action need more than xx msec" is activated, the runtime for all actions
that run longer than the defined time is output. This allows limiting the number of outputs and
less load is created by the measurement itself (the function OnTime will not continue to cycle).
Example
Check the Request/ActionQueues
This parameter
allows recognition of slow growth in the queue, which would only lead to error
message "more than 10000 Actions to Work" after several hours or days. Individual pictures
can also be checked for correct action programming.
Value "ScanRate" can be used to define after which amount of new jobs that the length of the
queue should be checked. If the queue has grown by more than the value defined with
Gradient, a notice in the form of a printf is output.
If you enter e.g. with ScanRate "100" and Gradient "30", then after 100 new entries (actions)
have been placed in the queue, a check is performed to determine whether the queue has
