Section 5
Supported services
When publishing a measured value, the user must take care of which measured value data attributes
are added to a data set. If the measured value is event-handled , then one can add that value directly
to the data set. If the value is not event-handled , it is recommended to connect the value desired to
be published to a MVGAPC function block (in ACT) and then use the measured value given by the
MVGAPC.
MVGAPC - IEC 61850 generic communication I/ O functions have the event-handled measured
values (can be added directly to the data set).
Generic function blocks are provided to make available to the 61850 bus signals that are not defined
inside any of the available function blocks. Example of such functions include:
• SPGAPC - IEC 61850 generic communication I/ O functions
• DPGAPC - IEC 61850 generic communication I/ O functions
• MVGAPC - IEC 61850 generic communication I/ O functions
Control
Of the different control sequences, the 'direct-with-normal-security' and ' SBO -with-enhanced'
security are supported (defined by the ctlModel parameter, IEC 61850-7-2).
Check bits; interlock check and synchrocheck check, are only valid for LN types based upon CSWI
class.
Verification of Originator Category is supported, see also PIXIT.
GOOSE simulation
Receiving GOOSE simulation is supported according to IEC 61850-7-2.
You can enable the GOOSE-simulation feature in PST (Parameter Setting Tool) by setting
"AllowSimulation" to "Yes", IEC 61850 is set to "true" and GOOSE simulation activates. From then
on, receiving GOOSE with simulation-bit (set in the GOOSE header) is treated as real GOOSE and
the original real GOOSE is ignored.
If you switch the simulated GOOSE off, the GOOSE receiver does not automatically switch back to
the real original GOOSE. Internal GOOSE data is set to invalid, because the simulated GOOSE is
missing. Only if the GOOSE-simulation feature is switched off in PST by setting
"AllowGOOSESimulation" to "No" ( ...LD0.LPHD1.Sim.stVal , IEC 61850 is set to "false"), the real
GOOSE becomes active again and simulated GOOSE is ignored.
Service tracking (available for IEC 61850 Ed2)
The LN ALTRK1 allows to track service parameters. The service parameters will stay visible after the
execution of service. For this purpose, common data classes are specified which contain the
parameters of the services according to IEC 61850-7-2 Ed2.
These data objects for service tracking are supported:
• Tracking of services :
•
•
•
•
•
•

If the PST setting "AllowGOOSESimulation" is set to "No" (default), all operations to
LPHD.Sim data object will be rejected.
