I/O refreshing involves cyclically transferring data with external devices using
preset words in memory. I/O refreshing includes the following:
All I/O refreshing is completed each cycle without time slicing. I/O is always
refreshed after the instructions in the user program are executed.
Peripheral servicing involves servicing non-scheduled events for external
devices. This includes both events from external devices and service requests
to external devices.
Most peripheral servicing for CS1D PLCs involved FINS commands. The spe-
cific amount of time set in the system is allocated to each type of servicing
