I am loading a program to test the LED on the s7-1200 PLC, CPU 1212c  AC/DC/RLY:

input i0.0 activate Q0.0 nothing is connected just checking led(in/out) on plc and its on

input i0.1 activate Q0.1 nothing is connected just checking led(in/out) on plc and its on

... all the way to..

input i0.6 activate Q0.6 nothing is connected just checking led(in/out) on plc and Does not come on

input i0.7 activate Q0.7 nothing is connected just checking led(in/out) on plc and Does not come on

*the picture shows the basic program. The LED on the Input side turns on but the Output side does not for i0.6 or i0.7

How can I fix it?

Thank you!!

 I do not have wires connected to the PLC. I am having a problem with the Relay inside the PLC as you can see in the pictures. 

The Output LED indicator does not come on when control by input i0.6 and i0.7. It does not make the clicking noise. 

hi,
Input "Tag_5" (% I0.6) is not activated in your network 3, it is normal that Led Q0.6 remains off!

mirip.

Hello,

Have a good look at your PLC , there is no output 0.6 and 0.7

When I start having the problem I had a expansion i/o module. That was the reason why I start testing with Q0.6 and Q0.7. But then I find out that the input i0.6 and i0.7 were not controlling any digital output build in the PLC (Q0.0 to Q0.3)

I do not know what cause it, but It was SOLVED when I reset it to factory settings.

Thank you
