hi dechen, see this manual about the S7-300 modules: SIMATIC S7-300 S7-300 Module data there you will find the wiring-diagrams of the DO-modules. Check if you connected the power-supplies. But there are some more questions of things we need to know to help you: What indication do you expect? Do you set an DO and nothing happens? How do you set the DO? Which module do you use exactly? the more we know, the more we can help, regards, |
