I/O Refreshing and Peripheral Servicing
I/O refreshing updates general-purpose I/O status. All I/O is refreshed in the
same cycle (i.e., time slicing is not used). I/O refreshing is always performed
after program execution.
Data is exchanged every cycle between predetermined areas and the Motion
Control Modules.
Data is exchanged cyclically with external devices using preset words in
memory. Cyclic refreshing includes the following:
All I/O refreshing is performed in the same cycle (i.e., time slicing is not used).
I/O refreshing is always performed after program execution.
Peripheral servicing involves servicing non-scheduled events for external
devices. This includes both processing for service requests from external
devices and service requests to external devices. Most peripheral servicing
involves FINS commands.
