Chapter 9. PLC Link Communication Function
The triggered transfer scan cycle and triggered data transfer operations are as
follows.
Data transfer is started for all sheets for which trigger device = ON is detected.

“Trigger ON” cannot be detected if the trigger device is turned
on and o by PLC on a cycle shorter than the scan cycle.

When the [Trigger device initialization] setting is [Yes], the trigger device is turned
off immediately after the trigger is detected. If the trigger device is turned off by
the trigger device initialization function, its status is the same as when the C1M
confirms that the trigger device is off. Therefore if the trigger device is turned on, it
is detected in the next trigger device scan.
