FB Prototype SYS_OPRS_MNGT
Input parameters
Output parameters
Description This function block allows to define the operational communication parameters
needed to manage the delay to execute the Modbus RTU and/or Modbus TCP
communication agents. The function block provides also information on the
application actual cycle time and the maximum and minimum cycle time reached
during normal operations. Of course, it should not be used in a timer task
otherwise you will get the task execution time.

Caution
In order to avoid communications and/or operational problems, SYS_OPRS_MNGT
must be used in a sort of “one-shot” mode at CPU Power-ON (and not cyclically).
