2.1.4
Change Group
2.1.4.1 Purpose of the Setting Groups
Up to four independent setting groups can be created for establishing the device's function settings. During op-
eration, the user can locally switch between setting groups using the operator panel, binary inputs (if so con-
figured), the operator and service interface per PC, or via the system interface. For reasons of safety it is not
possible to change between setting groups during a power system fault.
A setting group includes the setting values for all functions that have been selected as Enabled during con-
figuration (see Section 2.1.1.2). In 7VK61 devices, four independent setting groups (A to D) are available.
Whereas setting values and options may vary, the selected scope of functions is the same for all groups.
Setting groups enable the user to save the corresponding settings for each application. When they are needed,
settings may be loaded quickly. All setting groups are stored in the relay. Only one setting group may be active
at a given time.
2.1.4.2 Setting Notes
General
If multiple setting groups are not required. Group A is the default selection. Then, the rest of this section is not
applicable.
If multiple setting groups are desired, the setting group change option must be set to Grp Chge OPTION =
Enabled in the relay configuration of the functional scope (Section 2.1.1.2, address 103). For the setting of
the function parameters, you can configure each of the required setting groups A to D, one after the other. A
maximum of 4 is possible. To find out how to proceed, how to copy and to reset settings groups to the delivery
state, and how to switch between setting groups during operation, please refer to the SIPROTEC 4 System
Description.
Two binary inputs enable changing between the 4 setting groups from an external source.
