This function manipulates the channels and analog backplane relays for switching
aspects so only those specified by ch_list are closed on the slots specified on the items
in the parameter list.
The actions associated with this function include:

first, it opens previously closed channels and analog backplane relays if they are no
longer being specified for closure on the slots specified with the parameter list
items.

second, it will close the desired channels and analog backplane relays as indicated
by the items in ch_list.

settling times will be incurred before command processing is complete.

this function has no effect on how the DMM is configured.

analog backplane relays may be specified in parameter list.
For example, if each of the six slots have Channel 1 closed then, specifying a channel
list parameter of "2002, 4004" with this command, would open Channel 1 on Slot 2 and
4 only. Then, close Channel 2 on Slot 2 and Channel 4 on Slot 4 while maintaining
Channel 1 closed on slots 1, 3, 5 and 6.
For channel patterns, the analog backplane relays that get manipulated (closed or
opened) are the ones that were specified when the pattern was created (see
channel.pattern.setimage
specified with the channel.setbackplane function. Another option for getting analog
backplane relays closed by the command is to include them in the ch_list parameter.
An error will be generated if:

syntax error in parameter string.

an empty parameter string or parameter string with just spaces or a channel pattern
that emulates an openall scenario.

the parameter string contains "slotX", where X = 1 to 6, or "allslots".

a specified channel or channel pattern is invalid.

channel number does not exist for slot specified.

slot is empty.

channel pattern does not exist.

a forbidden item is specified

does not support being closed like a digital I/O channel.

channel is paired with another bank for a multi-wire application.
Once an error is detected, the command stops processing. Channels will open or close
only if no errors are found and will remain unchanged with any parsing or syntax error.
This command allows you to bundle the closing of channels with opening since any
currently closed channel or analog backplane relay will open if not specified for closure
in the parameter. It guarantees that only the specified items are closed and no others
on the slots specified in parameters list..
