Dependable Process Station (DPS)
Overview
This control equipment is used for automated plant control, various operational processing and plant ON/OFF control.
I/O signals with the plant field are processed through IO modules and control logic is computed through a CPU module to control the plant.
Functions of the Dependable Process Station (DPS)
High-reliability Controller with High Speed and Capacity
The DPS is able to perform calculations as fast as every 5 millisecond, making it suitable for application in systems that require high-speed control.
In addition, as the high capacity means that control operations can be executed with fewer controllers than the MPS, systems can be configured at a lower cost.
| MPS | DPS | |
|---|---|---|
| Number of Modules | 1 - 500 modules/controllers | 1 - 9,216 modules/controllers |
| Number of IO Points | 8 - 4,000 point modules/controllers | 8 - 73,728 point modules/controllers |
| Minimum Computation Period | 10 ms | 5 ms |
| Number of Logic Sheets (Maximum) | Regular Sheets: 1,023 or 4,095 | Regular Sheets: 4,095 |
Flexible Hardware Configurations
To maintain safety while raising the utilization rate, redundancy mechanisms that ensure continued operation even when a specific area fails are required.
DPS Logic Solver supports single to four-level redundancy, and all other cards and modules support redundancy.
By freely combining configurations and only implementing redundancies where needed, customers can maximize plant utilization rates at the optimum cost.
| Module Name | Redundancy |
|---|---|
| CPU Module Logic Solver | 1~4 |
| Higher Order General Communication Module Network Adapter (NA) | 1~2 |
| Lower Order General Communication Module IOScanner (IOS) | 1 - 2 × 4 groups
|
| IO Module | 1~2 |
