Structure of the Function
The function of the Settings group switching is a supervisory device function. Accordingly, the settings and
indications of the settings group switching can be found in DIGSI 5 and at the on-site operation panel of the
device, below the general device settings respectively.
If you want to switchover a settings group, navigate to DIGSI 5 or proceed on the on-site operation panel of
the device, as follows:
•
Via the project tree in DIGSI 5:
Project -> Device -> Settings -> Device settings
•
Via the on-site operation panel of the device:
Main menu → Settings → General → Group switchover
The indications for the settings group switching can be found in the DIGSI 5 project tree under:
Project → Device → Information routing → General
Function Description
Activation
If you want to use the Settings group switching function, you must first set at least 2 settings groups in DIGSI
5 (parameter Number of settings groups > 1). You can set up a maximum of 8 settings groups. The settings
groups set in DIGSI 5 are subsequently loaded into the device.
Mechanism of the Switchover
When switching over from one settings group to another, the device operation is not interrupted. With the
Active settings group parameter, you are either specifying a certain settings group or you allow
switching via control (IEC 60870-5-103, IEC 61850) or via binary input.
Switching via Control
When using the Control function for switching, the settings groups can be switched via a communication
connection from the substation automation technology or via a CFC chart.
The communication protocols IEC 60870-5-103, IEC 60870-5-104, IEC 61850, DNP or Modbus TCP can be used
for switching the settings groups via a communication connection.
In order to use a CFC chart for switching, you must create a new CFC chart in DIGSI 5. Create the CFC chart in
the DIGSI 5 project tree under Name of the device → Charts → Add new chart. Link the signals that control
settings group switching in the CFC chart.
Switching via Binary Input
There are 3 appropriate input signals available for switching via binary inputs. These input signals allow selec-
tion of the settings group via a binary code. If one of the 3 signals changes, the signal image present will, after
100 ms (stabilization time), result in switching over to the appropriate settings group. If only 2 settings groups
must be switched over, only 1 binary input is required. The following table shows the possible binary codes
(BCD) and applicable settings groups (PG).
