channel.clearforbidden()
Example
To clear Channels 2, 4, 6, and 8 of Slot 2 from being forbidden to close:
channel.clearforbidden('2002,2004,2006,2008')
To clear all channels from being forbidden to close:
channel.clearforbidden('allslots')
channel.close()
Function
Closes specified items in channel list parameter without opening any channels.
Usage
channel.close(<ch_list>)
ch_list: A string listing the channels and channel patterns to close.
Remarks
This function closes channels and channel patterns (specified by ch_list). These
closures are appended to the already closed channels (no previously closed
channels are opened by this command).
The ch_list parameter can include analog backplane relay items.
For items specified in ch_list, this function closes the associated channels along
with any associated analog backplane relays. For channel patterns, the analog
backplane relays that get closed are the ones that were specified when the pattern
was created (see channel.pattern.setimage() (on page 13-63) and
channel.pattern.snapshot() (on page 13-66)). However, for channels,
they are the ones specified with the channel.setbackplane() (on page 13-
70) function. Another option for closing analog backplane relays with this command is
to include them in the ch_list parameter.
This command has no effect on how the DMM is configured.
