Communication protocol manual
• VMSQI - Voltage sequence measurement
• VNMMXU - Phase-neutral voltage measurement
• MVGAPC - IEC 61850 generic communication I/ O functions
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.
If the PST setting "AllowGOOSESimulation" is set to "No"
(default), all operations to LPHD.Sim data object will be rejected.
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.
