Glossary
User address
A user address comprises the name of the user, the national code, the area code and the user-specific phone
number.
Users
From DIGSI V4.6 onward , up to 32 compatible SIPROTEC 4 devices can communicate with one another in an
Inter Relay Communication combination. The individual participating devices are called users.
VD
A VD (Virtual Device) includes all communication objects and their properties and states that are used by a
communication user through services. A VD can be a physical device, a module of a device or a software
module.
VD address
The VD address is assigned automatically by DIGSI Manager. It exists only once in the entire project and thus
serves to identify unambiguously a real SIPROTEC 4 device. The VD address assigned by DIGSI Manager must
be transferred to the SIPROTEC 4 device in order to allow communication with DIGSI Device Editor.
VFD
A VFD (Virtual Field Device) includes all communication objects and their properties and states that are used
by a communication user through services.
VI
VI stands for Value Indication.
