To create a channel pattern using the remote command interface, use the
channel.pattern.setimage
or the
channel.pattern.snapshot
command. Refer to Instrument Control Library in the Series 3700 Reference
Manual for more details.
NOTE
Channel patterns inherit the delay times of the individual channels that
comprise the pattern. For information on the sequence of close
operations on multiple channels, refer to
Connection methods for
close operations
(on page 4-15).
NOTE
Marking a channel as 'forbidden to close' deletes any existing channel
patterns containing that channel.
Channel pattern storage
Channel patterns:
are part of saved setup data and restored when a setup is recalled.
are deleted with a system reset or reset of a channel associated with a
pattern.
are allocated 32KB of memory within the Series 3700 mainframe for all
channel pattern storage.
The number of channel patterns you can store varies with the number of
characters of the channel pattern name, the number of characters used in listing
the switching channels, and the number of characters in the name of the DMM
configuration. 32KB of memory is equivalent to 32,000 characters. If each
channel pattern name is five characters long, and each pattern is comprised of
five channels, and the channel list is comma delimited (for example,
"2003,4003,2005,4005,2915"), then you can store 642 channel patterns. You
can store additional channel patterns by decreasing the number of characters in
each channel pattern name or the number of channels in the channel pattern
image. Conversely, you store fewer than 642 channel patterns by increasing the
number of characters in the channel pattern name or number of channels in the
channel pattern image.
To see how much of the channel pattern memory is available or used, see the
memory.available
or
memory.used
ICL commands. Refer to Instrument
Contol Library (ICL) in the Series 3700 Reference Manual for more details on
these commands.
