The remainder of this section describes how to define a scan list,
select input and output trigger sources, and so on.
Defining a Scan List
A Scan List may be defined using the SCAN command. The syntax
for the SCAN command is shown below:
[:ROUTe]
:SCAN
<scan
list>
:DELete
[:ALL]
:SCAN?
The <scan list> is the same as a <channel list> used with the
CLOSE, OPEN, and PATH commands, but with one addition:
special keywords may be used to indicate that all channels
controlled by the 1257 are placed in the state as recalled from
nonvolatile memory.
In short, the <scan list> is comprised of:
A)
Individual channel designators. Examples:
1(0)
1(37)
1(323)
B)
A list of single channels, separated by commas:
1(0,2,4,6)
1(9,2,1,10)
C)
A range of relays, separated by a colon:
1(1:8)
1(10:2)
D)
A path name:
Path1
Thispath
E)
A state name. State names begin with the letters “STATE”,
and end with a number between 0 and 100. The following
are valid state names:
STATE0
STATE7
State53
State100
For example, the commands:
PATH:DEF example,(@1(0,5,10,13))
SCAN
