Communicating with PC and Programmable Controller
When [Level] is Selected as Trigger Mode and [OK Pulse] is
Selected for [OK/NG Output]
Reading is repeated while the TRIG signal is ON until reading is successful, and
reading is exited when it is successful.
Therefore, this setting executes one output per trigger input.
If the TRIG signal is turned OFF before reading is successful, reading failure will result.
Even if an item other than [NG Pulse] is selected for [OK/NG Output], this signal will perform the
same operation as when [One Shot] is selected.
