When "Output Control" Is Set to "Synchronization Output"
This method enables synchronization between processing timing on the line and timing for output of
controller results. After the STEP signal has turned on the number of times set in "number of delay" in
the communication specifications, measurement results will be output the next time the STEP signal
turns on.
Reference
When the communication specification "Output Control" is set to "Synchronization output", levels will be
●
counted according to the number of times the STEP signal turns on. For this reason, perform settings so that
results are output only once for each measurement. (1 unit for [Judgement Output], 1 data item for [Data
Output])
Reference:
Only designate the STEP signal for measurement command input.
●
When measurement using serial commands and continuous measurement are performed, the output time will
not match and this can cause controller malfunctions.
Example) Stepped transmission line utilizing star wheel
The discharge timing for when a defective part is found and the measurement results output timing can

be synchronized.
