Issue

When a command is done over an element, it is very useful to know who done it. For example, when operation “open switch” is done by a CSWI, the originator is not stored in ACT common data class. This comment is related as a new CDC required for a comment on part 7-4.

Proposal

Add origin attribute of Originator type, to ACT common data class or

Define a new common data class (ACI) as follows:

q Quality
t TimeStamp
origin Originator
configuration, description and extension
operTm TimeStamp
d VISIBLE STRING255
dU UNICODE STRING255
cdcNs VISIBLE STRING255
cdcName VISIBLE STRING255
dataNs VISIBLE STRING255

Some clarifications why that TISSUE has been raised:
Typically, control operations and data of a control CDC are used to operate a device. These data have the attribute "origin" (with FC=CO) in order to determine the originator of a control.
In some cases, GOOSE mesages are used instead. In that case, the conteol value is transmitted with a data of the CDC ACT. So far, it was not possible, to supply the "origin" information with such an operation request. With the proposed extension, this will be possible. 		14 Jun 05 In Force (green)

Final Proposal:
accepted as proposed by Christoph Brunner on March 29th. Data Attribute origin will be added as optional in the ACT CDC.
02 Apr 05 Ballot Period
Also with the client/server based control services, the originater (the client) is known. Still we have introduced origin in the CDCs (not only as status ST but also as control CO). Therefore, I would suggest to add it as optional to the CDC ACT.
I would propose the following text for the final proposal:
"Basically accepted. Add an optional attribute origin of type Originator to the CDC ACT" 		29 Mar 05 Discussion (red)
