Siemens Digital Output module

I have a s7 300 digital output module.. the address start at Q16.0 to Q16.7..i have tested each address and it give 24V dc exept for Q16.6 that gives 11V dc only.. Does it mean that Q16.6 terminal is defective??


thank you

Hello,

Plug out front connector and replace it with different one, check voltage again, maybe connector is broken.

Best regards
