List of channels and redundancy
A description of this resolution:
- Configuration of the channel list
From V8.0 on, the channel list is no longer also transmitted during updating, i. e. the channels configured in the RS are relevant to all PS-red.‘s connected to and must have suitably been rated.
The following applies to previous versions:
For all PS-red.‘s connected to one RS, assignment of cables must be configured such that same channels are assigned in the same way. If not, the channels of the RS will have to be configured anew after every update.
To prevent errors, the problem must be taken into account already during engineering.
"List of channels and redundancy" resolves the following:
When updating the redundancy station the list of channels of PS-red. is also transmitted in the KNSRV.xxx.
This means that the current list of channels in the RS is always the one of the PS-red. which was updated last.
This, however, must not inevitably be the same one of the PS possibly to be taken over so that in this case the RS works with a wrong list of channels.
Applies to all versions in case different channel lists were assigned to the PS-red. connected to a RS.
