hi Reyntjensmi, have a look to the following manual. SIMATIC S7-300 CPU 31xC and CPU 31x: Technical specifications in Chapter 8.7 you find a block diagram of the integrated digital I/Os: As you can see, the module needs a M that the LEDs can ligth up. Without any wiring on the modules the LEDs won´t work. hope this helps, regards, |
