Recently Ive noticed that it is not possible to set the output on older raspberry ( B+)
The GPIO pin is constantly low when is set as Output. Inputs works fine.
Just curious is anyone else have this problem as well.

I'm using latest runtime on raspi ( and Codesys SP10 patch2.

I have the same problem on a raspberry pi 3, newest jessie image.

An old reason was that I added a new Ethernet connection between. So the Adresses of the Outputs (QX...) changed.

But now, new installation I have the same thing here. Can't set up an output, or read any inputs. With wiringpi i can set and check all the GPIO's.
Hope you (and me) can be helped.
