  • Status changed from New to In Progress
  • 61850 Standard 7-4 added

The tissue proposal= SwModKey is solely impacting check conditions for local operation.
Is it possible to have a local operation over the 61850 interface with orCat=1? sCtl16 PIXIT entry Ct29 states: Does the IED allow control with orCat=1 or 4 over the communication

When Ct29=Y the SwModKey shall allow/prohibit local operation over the communication. We may add a new conditional control test case.

When present, Repeat sCtl7, using orCat=2 or 3, with SwModKey = true and false and verify same result.

#3

Updated by Richard Schimmel 11 days ago

See solution:
The SwModKey is intended to bypass the interlock conditions for local control (typically via the display on the IED). Considering there is no Check conditions for the local/display control the SwModKey will indicate if the interlock check shall be performed or ‘bypassed’.

Proposal:
Update sCtl7 to verify that SwModKey has NO impact on the Operate() service from the remote/station level (orCat=2 or 3). The expected result shall be exactly the same.
