Special functions for input bits IR 00003 through IR 00006 are set in DM 6628:
A leakage current can cause false inputs when using 2-wire sensors (proximity
switches or photoelectric switches) or limit switches with LEDs. False inputs
won’t occur if the leakage current is less than 1.0 mA (2.5 mA for IN00000 to
IN00002). If the leakage current exceeds these values, insert a bleeder resistor
in the circuit to reduce the input impedance, as shown in the following diagram.
If a sensor power supply is turned ON when the PC is ON and ready to receive
inputs, surge current from the sensor may result in an incorrect input. To prevent
improper operation, use the following type of programming in the ladder pro-

The input impedance, input current, and OFF voltage may vary depending on the
input being used. (IN00000 through IN00002 have different values.)
