Description

In the DO available for teleprotection in LN PSCH, there is only blocking, permission and trip.
The following information also exist and need to be added:
- disable of recloser cycle
- closing order of circuit breaker
- transmission of a generic boolean information

Use cases:
PSCH groups applications sending signals to other line ends.
Disable of recloser cycle : an application identifies a fault on an underground cable. Reclosing should not happen in this case. The most consistent approach would be to add a DO TxDisable, RxDisable to PSCH.
Closing order of circuit breaker : in some cases, substation level automatons send closing orders to the other line end. The most consistent approach would be to add a DO TxCls, RxCls to PSCH.
Generic information : in some cases, substation level automatons send generic boolean information to the other line end, e.g. position of cb. The most consistent approach would be to add a DO TxOnOff, RxOnOff to PSCH.
