b) Multi-CPU System Synchronized Scan Setting (Sync Scan)
Set the scans for which the start of the scans are to be synchronized between CPU
Module 1 and CPU Module 2. The start of processing will be synchronized between
the set scans. The scans must also be synchronized to enable sharing data between the
two CPU Modules.
The default is to synchronize only the high-speed scans. Nor-
mally, use the default setting.
