MVP 2023 kratmel Posted October 20, 2019 MVP 2023 Report Share Posted October 20, 2019 What type of input: npn or pnp is used? Is it n/p pin connected acording to the manual? 14 hours ago, KurtL said: The LEDs 4,5,6,7 (on the I/O module are on) It is the 4, 6 status led - it must show the input pulse on/off. Where is connected 5,7 pin? Link to comment Share on other sites More sharing options...
