The response will be changed by channel.setbackplane(), replacing the analog backplane
relays with the new specified list.
The response will be cleared if channel.setpole() sets a new pole selection.
The analog backplane relays indicated by this response are not used or affected by:
• dmm.close() or dmm.open()
• scan.execute() or scan.background() if channel is configured for measuring
The parameter string can contain "slotX", where X equals 1 to 6, or "allslots".
An error is generated if:
• A specified channel does not exist for the card installed in a slot
• A channel pattern is specified in parameter list
• A specified channel does not have analog backplane relays associated with it, such as digital I/O
• An analog backplane relay is specified in parameter list
When channelList contains multiple items, the string returned includes the analog backplane relay
channels of a single channel separated by a comma. A semicolon is used to delineate channels.
For channel patterns, the analog backplane relays must be specified when creating the pattern in the
channel list parameter — see channel.pattern.setimage() or
channel.pattern.snapshot(). Therefore, to see the channels and analog backplane relays
associated with a channel pattern, use the channel.pattern.getimage() function.
Command processing stops as soon as an error is detected and a nil response is then returned. No
partial list is returned.
For digital I/O, DAC, and totalizer channels, nothing is returned.
