Solution
To resolve the problem, you have the following options:
Hot swap the ASI module EIA 921 00.
or
Reset bit 2 for the ASI control word (output word 9) and then set it again.
You can execute this
manually in the animation table
or
by implementing it in the program.
Example code
In this example bit 2 of the ASI control word is set to FALSE for the first 100 ms after the PLC starts.
When the 100 ms have elapsed bit 2 is reset to TRUE.
