Input ON delay, input OFF delay functions

This function changes an input signal when a predetermined time has passed after an actual input change.
A delay time can be set for each input change pattern, OFF to ON or ON to OFF. In addition, the function prevents incorrect
inputs caused by noise since a pulse of a certain time length is not taken in a module.
Input ON delay
The ON delay is the minimum ON time of the actual input signal required before the safety input signal changes from OFF to
ON.
Ex.
When 5ms is set, the safety input signal turns to ON after the actual input signal is ON for at least 5ms.
Input OFF delay
The OFF delay is the minimum OFF time of the actual input signal required before the safety input signal changes from ON to
OFF.
Ex.
When 5ms is set, the safety input signal turns to OFF after the actual input signal is OFF for at least 5ms.
Setting procedure
The "Input ON delay" and "Input OFF delay" times can be set from the "Parameter Processing of Slave Station" window of the
engineering tool.
The setting range is 0 to 1000ms (in 1ms steps)
The default value is 5ms.
• When "Wiring selection of input" is set to "1: Double wiring (NC/NC)" or "2: Double wiring (NC/NO), set the
same value as Xn+1 for Xn (n: even number).
• When "Input mode setting" is set to "1: Not used", this parameter will be ignored.
• In addition to this setting value, the safety refresh response processing time and the hardware response
time are also added as delay time for safety input signal switching. (Safety refresh response processing
time: 10ms, hardware response time: OFFON (0.5ms), ONOFF (1.5ms))
