When "Output Control" Is Set to "Handshaking"
Output the measurement results if controller is synchronous with external devices. If this function is used
when multiple measurement results are output in sequence, it enables efficient and effective data
transfer.
Inputting a measurement trigger in the STEP signal
Example) When 3 expressions are set in [Parallel Data Output]:
Reference
The output signal functions the same as when "Output Control" is set to "None".

Input signal
Signal
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 in the following cases:
The receiving system for external devices is complete
●
DSA
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.
