Function
You can set up a link in any operating area between the HMI unit and
the connected NCU/PLC units via the operator interface.
Activate the channel switchover key. The currently existing connection
is displayed by means of the highlighted softkeys (horizontal, vertical)
if the channel menu is active.
Channel switchover
You can switch to other channels by means of the vertically arranged
softkeys.
Group switchover
Use the horizontal softkeys to switch over to a different group; the
channels of the current group are now displayed on the vertical
softkeys. Switchover to another channel (and if necessary to another
NC) only takes place upon activation of a vertical softkey.
NC switchover
You can change to another NC via the vertical softkeys if the channel
is not on the current NC.
