Synchronization Cycle Timing Control Mode - Mitsubishi Electric NZ2GN2S1-16D User Manual

Synchronization cycle timing control mode

Controls I/O by using the time taken from a start of synchronization cycle to when the I/O has changed.
Compared to the I/O control performed every synchronization cycle, the I/O control using the synchronization cycle timing
control mode has the higher resolution, enables a user to acquire the more precise time when an input signal has changed or
to change an output signal at more precise timing.
The synchronization cycle timing control mode has the following two types.
• Synchronization input timing acquisition control ( Page 161 Synchronization input timing acquisition control)
• Synchronization output timing setting control ( Page 163 Synchronization output timing setting control)
Synchronization input timing acquisition control
A time when an input has changed can be acquired based on the synchronization cycle start timing.
 The I/O module sends the following information to the master station at each synchronization cycle.
• Synchronization input timing information X0 OFF to ON: Storing the time when the input has changed from off to on.
• Synchronization input timing information X0 ON to OFF: Storing the time when the input has changed from on to off.
 Synchronization input timing information X0 OFF to ON: 500s, Synchronization input timing information X0 ON to OFF:
No change of ON to OFF
 Synchronization input timing information X0 OFF to ON: No change of OFF to ON, Synchronization input timing
information X0 ON to OFF: 800s
 Synchronization input timing information X0 OFF to ON: No change of OFF to ON, Synchronization input timing
information X0 ON to OFF: No change of ON to OFF
