General
Each ACESYS block consists of:
- Program function block and associated program
- Faceplate for the object
- Dialog Faceplate
- Different sub Faceplates
- Simulator Faceplates
- Help look-up
- Design manual
Faceplate Layout:
1) Tag code and Description
2) Actual Status
3) Different data - depending of selected tab
4) Tab Select
5) Info faceplate
6) Interlock faceplate
7) On-line Help
8) Close Button
Control Principles
For a specific process controller, ACESYS constitutes a comprehensive collection of subroutines. All controlled units are treated as objects in the program. This ensures that the basic functions are of a well-proven design and that changes to the behaviour of an object can be done in a safe way. All I/Os and internal variables are named in a structured way in order to avoid the need for detailed knowledge of the physical addresses. Furthermore, a textual description is attached to all names to increase readability. The program is well documented with headlines and descriptions.
Closed loop control is enabled with modular PID controller software allowing application of simple as well as very complex loop functions.
The process is divided into a number of departments each describing main process equipment like the kiln, the raw mill etc. Each department is in turn organised through Groups, Routes and Units (Motors etc.), each of which will be described below.
A department is divided into Groups representing the logical control sequences needed for the control of the department. A Group controls a number of Routes and/or motors and other units and typically makes one separate section of the department e.g. a clinker transport or raw mill hydraulic.
In the ECS-system alarms from units within a group or route that are stopped can be suppressed. It is possible individually to configure alarms not to be suppressed.
