This associates the name dmm_to_P177 with the close channel
list, channels 205 and 305, on the module whose name is defined
as “matrix”:
PATH:DEF dmm_to_P177,(@matrix(305,205))
This associates the name oscope1 with a close channel list for
channels 0 and 3 on plug-in module 3 and an open channel list for
plug-in module 5, channel 15.
PATH:DEF oscope,(@3(0,3)),(@5(15))
Once a path name is defined, it may be used in a CLOSE or
OPEN command:
OPEN (@path1)
CLOSE (@dmm_to_P177)
CLOSE (@path1,dmm_to_P177,7(0:10))
A CLOSE command, for a given pathname, will effectively close all
channels listed on the close channel list and open those listed on
the open channel list.
An OPEN command, for a given pathname, will open all channels
listed on the close channel list. Channels on the open channel list
are ignored when using this command.
Path names may also be used in defining an “Include List”, an
“Exclude List”, or a “Scan List”. The following sections describe
each of these concepts.
When using path names with the “Include List”, “Exclude List” and
“Scan List”, the presently defined path is used. That is, if the
following sequence of commands is received:
PATH:DEF PATH1,(@5(0),7(0))
INCLUDE (@PATH1,1(0))
PATH:DEF PATH1,(@6(17),8(23))
CLOSE (@1(0))
then the path definition in effect when the INCLUDE command
was defined is used. For the example shown then, channel 0 on
module 5 and channel 0 on module 7 are affected; channel 17 on
module 6 and channel 23 on module 8 are NOT affected.
Removing Path Names
Astronics Test Systems
The PATH:DELETE command may be used to delete a single path
name from the list of known path names. The PATH:DELETE:ALL
command may be used to remove all presently defined path
names.
