PLC Master Calibration
The PLC Master Calibration processing item creates calibration data as follows: The axis
movement that is necessary for sampling is calculated in advance. Then, the following routine is
repeated: the PLC moves the external device, it sets the axis movement in the FH/FHV series
Controller, and then it sends a measurement command to the FH/FHV series Controller.
Reference the Calibration Data Reference item to access the calibration data that was created.
Refer to PLC Master Calibration of the Vision System FH/FHV Series Processing Item Function
Reference Manual (Cat. No. Z341).
Executing Calibration
●Vision Master Calibration (Homing operation selection is Enabled.):
External device PLC
FH/FHV
Outputs data
1: Moves to the axis
position when
Calibration is started.
Response that
movement is completed.
Repeats processing within
this frame until calibration
complete flag is ON.
2: Clear the measurement
results.
Response that clear
processing is completed.
3: Measurement Command
3.1: Measurement
Moves only each axis of next axis
movement amount when calibration
complete flag is OFF.
4: Moves only each axis of
next axis movement
amount
Response that
movement is completed.
• Next axis movement amount
(by each axis of external device)
• Calibration complete flag
