4-4-3 Sensor Power ON Delay (Input Units Only)
Function Overview When the I/O power has gone OFF, this function blocks inputs for the first 100
ms after the I/O power is turned back ON. The power ON delay allows the
sensor power supply to stabilize and prevents false input signals caused by
inrush current at startup. The Programming Device can be used to enable or
disable this function.
