The response indicates the analog backplane relays that will be used or affected by:
(on page 9-18) – used during processing of command
channel.close
(on page 9-21) – used during processing of command
channel.exclusiveclose
(on page 9-34) – used during processing of command
channel.open
(on page 9-42) – replaces the analog backplane relays with one
channel.setbackplane

(on page 9-46) – clears the analog backplane relays
channel.setpole
scan.execute (on page 9-162) or
channel pattern configured for switching
The analog backplane relays indicated by this response are not used or affected by:
dmm.close (on page 9-77)
dmm.open (on page 9-106)
scan.execute (on page 9-162) or
channel or channel pattern configured for measuring
The parameter string may contain ―slotX‖, where X equals 1 to 6, or ―allslots‖.
An error will be generated if:

an empty parameter string.

an empty slot is specified.

a specified channel doesn't exist for the card installed in a slot.

a channel pattern is specified in parameter list.

a syntax error exists in the parameter list.

a specified channel doesn't have analog backplane relays associated with it like
digital I/O.

an analog backplane relay is specified in parameter list.
When ch_list contains multiple items, the string returned will have the analog backplane
relay channels of a single channel separated by a comma. A semicolon will be used to
delineate between channels.
For channel patterns, the analog backplane relays must be specified when creating the
pattern in the channel list parameter (see
channel.pattern.snapshot
backplane relays associated with a channel pattern use the
(on page 9-37) function.
Command processing will stop as soon as an error is detected and a nil response will be
returned. No partial list will be returned.
