AUMA Aumatic ACExC 01.1 - External Change-Over of the Communication Channels; Details of the Change-Over

17.2 External change-over of the communication channels
A certain communication channel can be selected externally via the
change-over bits channel 1 and channel 2 in the process representation
output (page 34).
17.2.1 Details of the change-over
.
The change-over is only to transition of these bits, i.e. the change-over is
initiated by the transition 0 → 1.
.
If the bit for channel changing is set, the addition of the second bit does
not have any effect.
.
Transition from one channel to the other is supported, i.e. bits can be
changed simultaneously (e.g. channel A: 1 → 0 and channel B: 0 → 1).
The change-over is only performed if the bits in the process representation
input are set accordingly and both DeviceNet interfaces communicate with
the master.
