Controlling/Outputting through Parallel Communication
187
Inputting a measurement trigger in the STEP signal
Example) When 3 expressions are set in [Parallel Data Output]:
Note
●
The output signal functions the same as when "Output Control" is set to "None".
When "Output Control" Is Set to "None" (p.184)
Input signal
Signal
Function
DSA
This signal is used to request the next data transfer from external devices. The controller does not
output data until the DSA signal is ON. Turn the DSA signal ON the next time.
●
The receiving system for external devices is complete
●
The controller has completed measurement
The BUSY signal is on during measurement. As a result, the timing of when measurement is
complete can be understood by observing the BUSY signal.
When "Output Control" Is Set to "Synchronization Output"
This method enables synchronization between processing timing on the production 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.
