Synchronization input timing information
■Device number
Name
Synchronization input timing information X
■Description
When the synchronization cycle timing control mode is used, the input timing relative to the synchronization cycle start timing
is stored.
The time when the input has changed from OFF to ON, or from ON to OFF in one synchronization cycle is stored.
■Stored value
The stored value indicates the amount of time (unit: ns) that has passed from the synchronization cycle start timing to the
input change.
The following table lists the stored values.
Stored value
0 to 4294967294 (00000000H~FFFFFFFEH)
4294967295 (FFFFFFFFH)
Input time information
■Device number
Name
Input time information X
■Description
When the set time synchronization control mode is used, this area stores the time when the input has changed.
The detection time of input change (either rising edge or falling edge) is stored here. Select which detection time is to be
stored by setting ON/OFF selection flag (RWw4, RWw5).
A value in Input time information X (RWr10 to RWr8F) is updated only once in one synchronization cycle.
■Stored value
When the input has changed multiple times in one synchronization cycle, the time of first change is stored.
The following table lists the stored values.
Stored value
0 (minimum value)
4294967295999999992 (maximum value)

Appendix 2 Remote Register
Device number
RWr10 to RWr8F
Description
Shows that the input has changed at the timing of stored value.
Shows that the input has not changed within the synchronization cycle.
Device number
RWr10 to RWr8F
Description
Shows that no input change has been detected after data link establishment
of I/O module.
