Channel.exclusiveslotclose() - Keithley 3700A Series Reference Manual

Section 11: TSP command reference

channel.exclusiveslotclose()

This function closes the specified channels and channel patterns on the associated slots and opens any channels
that are not specified.
Type TSP-Link accessible
Function Yes
Usage
channel.exclusiveslotclose("channelList")
channelList
Details
This command allows you to bundle the closing of channels with the opening of channels. Any
currently closed channels or analog backplane relays open if they are not specified to be closed on
the slots related to the channels in channelList. Using this command guarantees that only the
specified channels and channel patterns are closed on the slots associated with channels in the
channelList.
For channel patterns, the analog backplane relays that are closed or opened are the ones that were
specified when the pattern was created (see channel.pattern.setimage() or
channel.pattern.snapshot()). For channels, the analog backplane relays are the ones
specified with the channel.setbackplane() command. If you do not want to use the
channel.setbackplane() command, you can close the analog backplane relays by including
them in the channelList parameter. When this command is sent:
•
Closed channels or analog backplane relays for the associated slots are opened if they are not
specified in the channelList
•
Channels or analog backplane relays specified by the items in channelList are closed
•
Any settling times and user-specified delay times are incurred before command processing is
complete
This function has no effect on how the DMM is configured
For example, if channel 1 is closed on each of the six slots, specifying a channelList parameter of
"2002, 4004" with this command opens channel 1 on slots 2 and 4 only. Then, channel 2 on slot 2
and channel 4 on slot 4 close. Channel 1 remains closed on slots 1, 3, 5, and 6.
The command is not available for digital I/O, DAC, and totalizer channels. Calling on one of these
channels generates an error. If the digital I/O, DAC, or totalizer channel is in the range of channels,
the channel is ignored.
An error is generated if:
•
The parameter string contains slotX (where X = 1 to 6) or allslots
•
The parameter string is empty or parameter string with just spaces
•
A specified channel is invalid or does not exist for the slot
•
Channel pattern does not exist or the image of the pattern is an empty channel list
•
A forbidden item is specified
•
Channel is paired with another bank for a multi-wire application

Affected by Where saved
A string that lists the channels and channel patterns to exclusively close on the
cards in associated slots (you can specify analog backplane relays)
