For electromagnetic contactors, set the parameters as follows.
*1 Adjust the values of input response time, input dark test pulse off time, and output dark test pulse off time according to the installation
environment and wiring length.
*2 Set double input discrepancy detection time to 100ms for mechanical switches and 20ms for sensor inputs as standard.
*3 For details on each setting range, refer the following manual.
 CC-Link IE Field Network Remote I/O Module (With Safety Functions) User's Manual
*4 Always set the parameters like this for this case example.
