CIM Issues #6549
Updated by David Haynes 9 months ago
1) One approach is to modify Part 9 so that a "lock closed" command and "locked closed" statuses are available to the user. If the meter itself will lock a switch open or closed, the issue goes away. The meter will ignore DER commands to open the switch. If this alone is the solution, then every switch everywhere must have this capability.
2) A software solution can be built that uses the SwitchPlan, SwitchOperation, and TagOperation elements from Part 3 to model a switch manager for use by parts 5 and 9.
3.) Whatever is implemented should utilize WG15's IEC 62351-8 Role Based Access Control recommendations. A role should be created that has rights to open and close a switch. Another role should be created that has the rights to open, lock open, close, lock closed, unlock, and unlock close the switch. Only one application in the utility back office should have the switch owner role and have the right to lock the switch. All others are limited to open/close commands.
