Programmer Operation<br />
<strong>2704</strong> Controller<br />
6.3.9. Digital Inputs<br />
Digital inputs are available on the <strong>controller</strong> which can be configured for the following<br />
programmer functions:<br />
Run<br />
Hold<br />
Reset<br />
Run/Hold<br />
Run/Reset<br />
Advance Segment<br />
Advance Program<br />
Holdback disabled<br />
Allows the program to be run from an external source such as a<br />
pushbutton or other event. The Run input is edge triggered.<br />
Allows the program to be held from an external source such as a<br />
pushbutton or other event. The Hold input is level triggered.<br />
Allows the program to be reset from an external source such as a<br />
pushbutton or other event. The Reset input is level triggered.<br />
Allows the program to be run or held from a single external input<br />
source<br />
Allows the program to be run or reset from a single external input<br />
source<br />
Selects the next segment from an external input source<br />
Selects the next program from an external input source. When this<br />
event occurs, the <strong>controller</strong> display will change to programmer<br />
view. Subsequent changes of this input source will cause the<br />
program number to increment.<br />
Disables holdback from an external input source<br />
For more information on digital inputs refer to Chapters 17 <strong>and</strong> 18. For configuration of<br />
these inputs see Engineering Manual Part No. HA026933.<br />
6.3.10. Program User Values<br />
Program User Values provide multiplexor facilities for the user. Each user value provides<br />
storage for a number of event values (currently 100). Each user value will normally be wired<br />
(in software) to call up another feature.<br />
The following example shows how the programmer user values may be used to call up<br />
different sets of pre-configured digital output values for different segments in a programmer.<br />
This would make use of the Pattern Generator described in Chapter 13, <strong>and</strong> assumes that an<br />
user value has been wired to a Pattern Generator.<br />
Program Segment 1 Program Segment 2 Program Segment 3 Program Segment x<br />
User Value 1<br />
Value 1<br />
User Value 1<br />
Value 6<br />
User Value 1<br />
Value 11<br />
User Value 1<br />
Value 15<br />
Pattern Generator<br />
output 1<br />
Pattern Generator<br />
output 6<br />
Pattern Generator<br />
output 11<br />
Pattern Generator<br />
output 15<br />
In each segment a different pattern of digital outputs is set up from the single value set in the<br />
User Value for each segment.<br />
