Issue

The Common Data Classe (CDC) DPC is widely used in IEC 61850-7-420 for fast reacting controls that don't have an intermediate state.
The usage of a SPC CDC would be more appropriate.
This affects the following data objects (DO):
- DCIP.EngCtl
- DCIP.CrankCtl
- DCIP.EmgCtl
- DCIP.DiagEna
- DFCL.FuelShut
- DFCL.EmgCtl
- DCHB.BoilCtl
- MFUL.AccFuelRs
- MFUL.AccOpTmRs
- DFLV.FuelStr
- DFLV.FuelStop

Proposal

Change CDC of the above mentioned DOs to SPC.
