Corrective action
• Increase the timeout time specified to the argument.
• Review and correct the user program (including other tasks which
execute motion CPU interaction functions).
• Review the program used for the request destination CPU module
and correct it to perform the processing requested from other CPU
modules, for example, by adding the WAIT instruction.
Check the specified value.
Check the specified value.
• Register the processing for the event (interrupt) and perform the
operation again.
