LN: Alarm handling Name: CALH
For a description of this LN, see IEC 61850-5. CALH allows the creation of group warnings, group indications and group alarms. The individual alarms, which are used to calculate the group indications/alarms/warnings, are subscribed from elsewhere. The calculation is a local issue, usually performed by a logic scheme.

LN: Interlocking Name: CILO
For a description of this LN, see IEC 61850-5. This LN shall be used to "enable” a switching operation if the interlocking conditions are fulfilled. One instance per switching device is needed. At least all related switchgear positions have to be subscribed. The interlocking algorithm is a local issue.

LN: Point-on-wave switching Name: CPOW
For a description of this LN, see IEC 61850-5. This LN shall be used if the circuit breaker is able to perform point-on-wave switching. In this case, the start signal for CPOW is OpOpn or OpCIs to be subscribed from CSWI. Then CPOW shall perform its entire dedicated algorithm using data objects from the allocated TCTR or local and remote TVTR (local issue) and shall then release a “Time Activated Control” (see IEC 61850-7-2) to XCBR. OpOpn and OpCIs shall be used if no "Time Activated Control” services is available between CPOW and XCBR. Alternatively, CPOW may be started by a control service acting on data object Pos.

LN: Switch controller Name: CSWI
For a description of this LN, see IEC 61850-5. This LN class shall be used to control all switching conditions above process level. CSWI shall subscribe the data object POWCap (“point-on-wave switching capability”) from XCBR if applicable. If a switching command (for example Select-before-Operate) arrives and point-on-wave switching capability” is supported by the breaker, the command shall be passed to CPOW. OpOpn and OpCIs shall be used if no Control Service is available between CSWI and XCBR (see GSE in IEC 61850-7-2).
