Switch Commands - Agilent Technologies Agilent 3499A User Manual

Switch Commands

These ROUTe commands are intended for use with all switching plug-in
modules. You cannot use these commands to change the state of bits in a
digital I/O module.
[ROUTe:]
CLOSe <channel_list>
CLOSe? <channel_list>
This command closes the switching channels specified in the
channel_list . The channel_list has the form @snn, where s is the slot
number and nn is the channel number. For all mainframes, slot 0 refers
to the 3499A/B/C control board. Valid slot numbers are:
3499A slots 0 through 5
3499B slots 0 through 2
3499C slots 0 through 9
The channel number, nn, is plug-in module dependent. Channel
numbers for plug-in modules are listed on page 70.
To close:
•
a single channel, use CLOS (@snn);
•
multiple channels, use CLOS (@snn,snn...);
•
sequential channels, use CLOS (@snn:snn);
•
groups of sequential channels, use CLOS (@snn:snn,snn:snn);
•
or any combination of the above.
Channels in a channel_list may not close simultaneously. The order in
which the channels close when operated by a single command is not
guaranteed. Use sequential CLOSe commands if needed.
The CLOS? query returns a "1" for a closed channel and a "0" for an open
channel. If you specify a list of channels, the query returns a comma
separated list of 0's and 1's, in the same order as the channel_list. The
returned values indicate the programmed state of the relay. This query
does not physically monitor a relay and cannot report a failed relay.
