The error occurs because channels 1(0) and 1(6) are on an include list together
and they are on an exclude list together. This creates a conflict since an attempt
to close channel 1(0) would attempt to close channel 1(6) due to the include list
association, but would be prevented from doing so by the exclude list.
The syntax for defining an exclude list is shown below:
The following examples illustrate the use of this command to define exclude
lists:
The first command establishes an exclude list of channels 0 through 19 on
module 1 and channels 0 through 19 on module 2.
The second command closes channel 0 on module 1.
The third command closes channel 11 on module 2. This command will cause
channel 0 on module 1 to open, since both channels are on the exclude group
together.
The fourth command closes channel 17 on module 2. Channel 15 is never
closed, since it is excluded by channel 17. Channel 11 on module 2 is opened
prior to closing channel 17, since channels 11 and 17 are on the exclude group
together.
The INCLUDE and EXCLUDE relationships of channels can cause multiple
closures and openings when commanding a single channel to close. For
example, assume the following commands have been executed:
After these commands have been executed, channel 0 of module 1 is closed.
Also, channels 1 through 4, 10 and 12 are closed, since these are on the same
include list as channel 0.
