Modes groups and channels

Every channel behaves like an independent NC. A maximum of one part program can be
processed per channel.
● Control with 1channel
One mode group exists.
● Control with several channels
Channels can be grouped to form several "mode groups."
Example
Control with 4 channels, where machining is carried out in 2 channels and 2 other channels
are used to control the transport of the new workpieces.
Mode group 1 channel 1 (machining)
Channel 2 (transport)
Mode group 2 channel 3 (machining)
Channel 4 (transport)
Mode groups (MGs)
Technologically-related channels can be combined to form a mode group.
Axes and spindles of the same mode group can be controlled by one or more channels.
An operating mode group is in one of "Automatic", "JOG" or "MDI" operating modes, i.e.,
several channels of an operating mode group can never assume different operating modes.
