Issue

Inconsistency with several control data objects (DOs) of LN DRCC having the same name as DOs of other IEC 61850-7-420 LNs but using different data types (CDCs):
- DRCC.OutWSet uses CDC APC, but ZINV.OutWSet and ZRCT.OutWSet use CDC ASG
- DRCC.OutVArSet uses CDC APC, but ZINV.OutVArSet uses CDC ASG
- The DOs OutPFSet and OutHzSet of LN DRCC use CDC APC, but the identically named DOs of LN ZINV (and also DRCT.OutPFSet) use CDC ASG
- DRCC.OutVSet uses CDC APC, but ZRCT.OutVSet uses CDC ASG
- DRCC.MaxVArLim uses CDC APC, but DRCT.MaxVArLim uses CDC ASG
- The DOs LodModBase, LodModFol, LodModFxExp, LodModAval and DCPowStat of LN DRCC use CDC SPC, but the identically named DOs of LN DRCS use CDC SPS

Proposal

- Modify the data type (CDC) from APC to ASG for the following DOs of LN DRCC: DeRtePct, OutWSet, OutVArSet, ImptExptSet, OutPFSet, OutHzSet, OutVSet, MaxVArLim, LodRamp, LodStop, LodSharRamp and LodWPct.
- Rename DRCC.DCPowStat to DRCC.DCPwrCtl
- Rename DRCS.LodModBase to DRCS.LodModBaseSt
- Rename DRCS.LodModFol to DRCS.LodModFolSt
- Rename DRCS.LodModFxExp to DRCS.LodModExptSt
- Rename DRCS.LodModAval to DRCS.LodModAvlSt
- Rename DRCS.DCPowStat to DRCS.DCPwrSt
