Communicating with PC and Programmable Controller
When [One Shot] is Selected as Trigger Mode and [Level] is
Selected for [OK/NG Output]
The OK and NG signals are expressed as level signals.
The signals are input when the BUSY signal switches from ON to OFF.
If [OFF] is selected for [NG Output], no outputs will be made via RS-232C when reading has failed.
If [Level] is selected for [OK/NG Output], this signal is turned ON/OFF to indicate the reading result
(i.e. whether reading is successful or has failed).
The signal is ON when reading is successful, and it is OFF when reading has failed.
