Execution channels
2.1.1 Setting the number of channels and their behavior.
Some of these parameters correspond to the common general parameters whereas others
belong to the general parameters of each channel.
Parameter. Parameter type.
NCHANNEL General machine parameter.
GROUPID General machine parameter of the channel.
CHTYPE General machine parameter of the channel.
HIDDENCH General machine parameter of the channel.
NCHANNEL
Number of CNC channels.
Possible values: From 1 to 4.
Default value: 1.
Associated variable: (V.)MPG.NCHANNEL
The use of channels is oriented to machines like dual-spindle lathes where each channel
has one of the spindles and two axes; machines with feeders, where the machine and the
feeder will be different channels; tool magazine loading and unloading system controlled as
an axis.
The CNC can have a single execution channel (single channel system) or several (multichannel
system). Each channel is a different work environment that can act upon a part of
or the whole CNC system. The difference between a multi-channel system and several
independent CNC's is that the channels can not only act independently, but also together;
in other words, they can communicate, synchronize with each other and carry out
coordinated actions.
The axes and spindles of a channel.
A channel can have a group of axes and spindles that act independently or in parallel with
the rest of the channels. It is also possible to configure a channel without assigning axes or
spindles to it at first; then, later on, axes and spindles may be added to it or removed from
it via part-program or in the MDI/MDA.mode.
Operation of a channel.
In order to be able to move an axis or spindle, it must be assigned to a channel. Each channel
can only control its axes and spindles, although via part-program or MDI/MDA it can
command movements to axes or spindles of other channels.
Each channel can execute a different program, be in an different work mode and have its
own data. The channels can share information through variables and arithmetic parameters
and, if necessary, they may be synchronized via part-program.
GROUPID
Group the channel belongs to.
Possible values: From 0 to 2.
Default value: 0 (it does not belong to any group).
Associated variable: (V.)[ch].MPG.GROUPID
Two or more channels may be configured to form a group. The channels of the same group
behave as follows.
Each channel may be in a different work mode, except in jog and automatic modes.
Toggling between the jog mode and automatic mode of a channel will affect all the
channels of the group that are in any of these modes; the channels that are in a different
mode will not be affected.
A reset in any of the channels of the group affects all of them.
Any error in any of the channels of the group interrupts the execution in all of them.
