WARNING
Inserting output modules can lead to uncontrolled system states!
This also applies if you insert input / output modules tilted on the bus module.
When inserting an output module, the outputs set by the user program become active
immediately!
We therefore advise you to set the outputs to "0" in the user program when removing the
output module.
If modules are not removed and inserted properly, neighboring modules via the
backplane bus can fail.
