OverviewΒΆ
Beside the Temperature Control process, a concept of 3-level zone management is offered by the PS564 library.
In this concept, a Temperature Control system consists of up to 255 groups, and each group consists of up to 255 zones.
The system refers to the whole machine. On the system level, it offers convenient monitoring as well as operating.
The groups are also the physical groups of the process which are normally close to each other. On the group level, several major functions are realised:
- Convenient monitoring as well as operating at group level.
- A group-wise programming of the control process (using Function Block TECT_GROUP) instead of programming the control process for each zone separately.
- Fault monitoring at group level.
- Coordinated output at group level.
It is not mandatory to apply the zone management concept for the control process. Instead, the user can apply it with full flexiblilty: He can apply 3 levels (system-group-zone) for a large system, or 2 levels (group-zone) for a middle size system, or even 1 level (only zone) for a small machine. However the more zones a system contains, the bigger the benefit of the zone management concept will be experienced by the user.
