Channel menu

5.2 Constraints

Using the channel menu
● For a system comprising several operator stations and several NCUs within the
framework of operator unit management, if the NC channels of several NCKs are
operated from one operator station.
● For a simple system with many NC channels, as an alternative to the standard
mechanism, the channel switchover can be made using the channel switchover key.
The basic philosophy of the channel menu is to provide - in a selection menu - the operator
with a view of the NC channels of all NCUs that are to be operated with the channel menu. In
conjunction with this, a logical grouping/structuring is introduced using the so-called channel
groups. The desired NC channel can be directly selected using the selection menu. Without
a channel menu, when pressing the channel switchover key, the NC channels must be
scrolled through consecutively until the desired NC channel has been selected. An operator
station can only be switched over across NCUs using the channel menu.
5.2 Constraints
● Only one SINUMERIK Operate on a PCU/ PC may be permanently connected to one
NCK. It is not possible to switch over to another NCK.
● SINUMERIK Operate of an NCU can only operate with its own NCK and cannot be
switched over to another NCU.
5.3 General structure of the channel menu
Overview
For the channel menu, a logical view is defined across all of the channels of all NCKs
involved; this logical view is structured in channel groups and this in turn in specific NC
channels.
A channel group list is defined for the channel menu in order to be able to switch over
operation. A channel group list comprises one or several channel groups. In turn, a channel
group comprises one or several NC channels.
In the channel menu, the channel groups can be selected using the horizontal softkeys.
The channels of a selected channel group can be selected with the vertical softkeys.
