Hi Mr and Mrs.
I have several reed switch (dry contact, normally open), connected in modules DI-IO16. In PLC have a function for counting the pulses. When reed switch is OFF the bit is 0, if ON the bit is 1, but, i need use some reed´s connected in a other digital board (way RS485 to communicate to PLC). The digital board work unlike the module DI-IO16. When reed is OFF the bit is 1, when ON the bit is 0.
For i counting the pulses is necessary use funcion negative transition contact (fall) or make a other function ?
Nice day for all
