Feedback of outputs in logo app.

Over 850.

M1 = V1104.0
M2 = V1104.1

and so on....

But they can be read flags just like digital outputs.

Why you can not select an operand "Q" (digital output) is a mystery to me. I hear that for the first time.

Just switch a digital network output behind a digital output and give it a free address that you can still access, e.g. V800.0.
And the condition of V800.0 then you ask in the app.

This will work with any unused V-bit address under V851.0.

There's nothing to apologize for. That can happen to anybody.

But you have to keep in mind that the bit addresses in the byte addresses, the byte addresses in the word addresses and the word addresses in the double word addresses are included.

VB0 contains the V bits V0.0 to V0.7.
VW0 contains the VBs 0 and 1 and thus the V-bits 0.0 to 1.7.
VD0 contains the VBs 0 to 3, the VWs 0, 1 and 2 and thus the V-bits 0.0 to 3.7.
If you, for example, the VW2 uses, you can not use the VBs 2 and 3 and the V-bits 2.0 to 3.7 for other purposes.
