*1: Adjust the values of Time of noise removal filter, Input dark test pulse OFF time, and Output dark
test pulse OFF time according to the installation environment and wiring length.
*2: Set Doubling input discrepancy detection time to 100ms for the mechanical switch and 20ms for
the sensor input as a standard.
*3: The parameter is added to the QS0J65BTB2-12DT of technical version D.
When a module of technical version C or earlier is used, the parameter is not available.
*4: For setting range, refer to the following.
CC-Link Safety System Remote I/O Module User's Manual
*5: Always set the enclosed option for this case example.
