Channel groups
Channel groups can be used for the logical grouping of functionally and/or
geographically linked plant sections, e.g. all transmitters and output elements of a
production hall. Up to 3 hierarchically classified channel group levels can be
formed. Note in this process that defined channel groups are not permitted to
contain sub-groups and channels simultaneously.
