[PSPNSV5-286] Read Implicit with Target ARUUID not handled properly in some cases - Hilscher Ticket

Details

The current implementation rejects any Read Implicit service with a Non-Zero Target ARUUID which does not refer to an active AR. According to IEC 61158-6-10 Version 2.4, the Target ARUUID shall be checked only in case of AR context sensitive record objects.
It is expected, that the protocol stack ignores the TargetARUUID when addressed object it not AR-specific.
If Read Implicit service with a Non-Zero Target ARUUID is used and addresses an object that is AR-specific (e.g. reading ModuleDiffBlock) AND the addressed AR does not exist, a wrong errorcode is used by protocol Stack.
Observed errorcode is 0xDE814005 but expected errorcode according specification is 0xDE81080C.
