Application And Setting Notes - Siemens 6MD85 Manual

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).

Copying and Comparing Settings Groups
In DIGSI 5, you can copy or compare settings groups with each other.
If you want to copy settings groups, select a source and target parameter group in DIGSI 5 in the device
settings, and then start the copy process. The device settings can be found in the DIGSI 5 project tree under
Project → Device → Settings → Device settings.
If you want to compare settings groups, it is possible to do so in all setting sheets for settings. You will then
select in addition to the active settings group, a 2nd settings group for comparison. Active setting values and
the comparable values are displayed next to each other. For settings that cannot be switched over, no compa-
rable values are displayed.
Indication of Settings Group Switchings
Every settings group shows an applicable binary indication as well as its activation and deactivation. The
process of settings group switching is also logged in the log for settings changes.

Application and Setting Notes

Parameter: Number settings groups
•
Default setting (_:113) Number settings groups = 1
With the Number settings groups parameter, you can set the number of available settings groups; you
can switch between these.
Parameter: Activat. of settings group
•
Default setting (_:114) Activat. of settings group = settings group 1
With the Activat. of settings group parameter, you specify the settings groups that you want to acti-
vate, or the mechanisms via which the switchover is allowed. You can switchover only between the settings
groups specified with the Number settings groups parameter. Parameter Value
