| Input Processing Program |
| |
* Input Processing Program processes data read by communication program at least once
every second.
* The program can perform engineering units conversion upon signal reception for all
analog received.
* The program performs signal validity check (Valid / Invalid) and signal correction (reference
temperature / drift limit).
* The program checks the alarm condition for all inputs based on its predefined setpoints. |
|
| |
| Output Processing Program |
| |
* Output Processing Program processes the selected analog and digital output points.
(The output points can be added, changed, or removed by engineering tools.)
* The program writes the output points to an output buffer and the Server-to-DAS
(Data Acquisition System) communication program transfer the output data to DAS. |
