The
IEC 61850 Server fieldbus driver accepts the write requests for read-only ('RO') data attributes (variables) with FC=SP; e.g. */setVal[SP]. And it refuses the write requests for data attributes with FC=CF, if SCL-configured as 'Set' (writable); e.g. */minVal[CF]. The driver responds the write requests with MMS error 3 (object-access-denied)
.The issue has been addressed and the write requests handling is now as expected.
To benefit from this fix:
- Update your zenon Software Platform to the latest build of zenon 14 or higher.
