Synchronous Output
CHECK
CHECK
The synchronous output function is used to synchronize the results output tim-
ing and the processing timing on the production line. The measurement results
are output when the next STEP signal turns ON after the number of STEP sig-
nals set under Num. of delays in the communications settings have turned ON.
When Sync. output is set, the delay is calculated by the number of times the
STEP signal turns ON. Therefore, set the measurement results output so that
the result is output only once for each measurement.
Set one unit for DO judge and one expression for DO data.
Set measurement command input to STEP signals only.
If TRIG or serial command measurement or continuous measurement are per-
formed, the output timing will no longer match and the Controller may malfunc-
tion.
Example: For Process-feed Production Lines Using a Star Wheel
The timing of the rejection of NG products and measurement results output
can be synchronized.
Twice
Once
If Num. of delays is set to 4, the measurement result will be output after 4
STEP signals have been detected.
