2.1.3 Change Group
2.1.3.1 Purpose of the Setting Groups
Up to four independent setting groups can be created for establishing the device's
function settings. During operation, the user can locally switch between setting groups
using the operator panel, binary inputs (if so configured), the operator and service in-
terface 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 configuration (see Section 2.1.1.2). In 7SD610 devices, four inde-
pendent 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 applica-
tion. 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.
2.1.3.2 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.
