Good morning, can you help me with the wiring of a flow sensor? I have a PLC S7-1200 DC / DC / RELY. sensor: flow sensor, GEORGE FISCHER, open collector output, I attach the technical doc in attachment. when I am wiring my sensor to the PLC, I can not detect the impulses, the LED of the sensor input does not light up. best Regards.
