PLC configuration _ no input signals received

Hello all,

I am using an L40 PLC, and I have the problem that I don't receive the inputs signals, but when I force the outputs signals, I can see the signals comming on the module. Do you know what can be the issue, that I don't see the inputs signals on the PLC configuation ?

Thank you!

Are the inputs used/called in your program ? ( Normally the I/Os are only updated, when they are used/called )

Or you must activate the "Update unused I/Os" option in the target settings :
