Groups Overview
In a CygNet SCADA context, a group is a collection of facilities organized into hierarchies. Facilities are included in hierarchies according to user-selected facility attributes and device attributes. Attributes can be defined in a way that makes sense in your organization. Specific attributes can then be chosen to identify levels in user-defined hierarchies. Hierarchies enable the collection and organization of information specific to the facilities and devices to which those attributes belong.
Group hierarchies provide a useful way to organize, navigate, and display select data from within a CygNet system that might contain very large amounts of data. They can be used to sort facilities in reports and on CygNet Studio and CygNet Vision screens by using facility attributes to capture only the information relevant to your organization. For instance, instead of performing a flat manual search of all your facilities for a subset of information, you can create a group hierarchy that enables selective searches for relevant facility attributes, like the remote device IDs for a specific operator at a specific location.
Common ways of interacting with groups include the following:
- Group Service (GRP)
- Group Manager utility
- CygNet Studio (and CygNet Vision)
- Scripting (CxGrp and CxHmiGrp)
The primary administrative interfaces with groups are the Group Service (GRP) and the Group Manager utility. Since most administrative user interaction with groups occurs through the use of the Group Manager utility, more emphasis is put on that usage than on use of the GRP service itself.
Additional Group Implementations
Group hierarchy terms and concepts appear CygNet in places besides the GRP Service. Some CygNet applications utilize the GRP along with other requirements, whereas other applications do not utilize the GRP at all.
Some CygNet applications use the GRP and the Group Manager utility, but also have unique group requirements of their own. If you are looking for group information relevant to one of these applications, see topics in their respective CygNet Help sections. CygNet implementations that use the GRP, but also have their own unique grouping and hierarchy requirements beyond the scope of the GRP are listed here.
Other CygNet applications do not depend on the GRP and do not use the Group Manager utility. They have their own implementations of grouping concepts and terminology. If you are looking for group information relevant to one of these applications, see topics in their respective CygNet Help sections. CygNet implementations that do not use the GRP, and instead use their own unique grouping and hierarchy concepts are listed here.
