Descriptors For
The 1260-134
The standard 1260-01T commands are used to operate the 1260-
134 module. These commands are described in the 1260-01T
User’s Manual.
Each 1260-01T relay command uses a
channel descriptor
to
select the channel(s) of interest. The syntax for a channel
descriptor is the same for all 1260 series modules. In general, the
following syntax is used to select a single channel:
(@ <module address> ( <channel> ) )
Where:
·
<module address> is the address of the 1260-134 module.
This is a number is in the range from 1 through 12, inclusive.
·
<channel> is the 1260-134 channel to operate. This is a
number in the range from 0-3, 10-13, 20-23 ……etc. See
Table 2-1.
Multiple individual channels may be specified using the following
channel descriptor syntax:
@ <module address> ( <chan1> , <chan2>
, . . ., <chanN> ))
A range of channels may be specified using the following channel
descriptor syntax:
@ <module address> ( <first channel> :
<last channel> ))
The following examples illustrate the use of the channel
descriptors for the 1260-134:
OPEN (@8(0))
Open channel 0 on the 1260-134
that has module address 8.
CLOSE (@8(0,3))
Close channels 0 and 3 on the
