Clause: 20.5.2.9

Paragraph:

Category: No impact on this part

Issue: Definition of addcause "parameter change in execution" is not clear enough.

Do we have this addcause when a data attribute with FC SP, SV, CF, DC or SE is modified during successive control service (between Select and Operate service)?

Proposal: 1) to avoid a confusion with Addcause "parameter change in execution", I propose to modify the name of Addcause "inconsistent parameters" with "inconsistent control parameters".

2) modification of definition of "parameter change in execution" with : "Control action is blocked due to running parameter change (writable data attribute with FC SP, SV, CF, DC or SE)."

Ballot until Editor
1) in principal accepted, but enumeration litteral cannot change for backward compatibility reasons.
2) parameter change means that either a change of either a configuration parameter CF, or of a setting SE, or SP has blocked the control. The definition is already specific enough.
Change of DC will not block a command.
A Substitution can lead to a position reached, blocked-by-health if the substution was required because of an hardware failure.
If further specification are required, then please use the comment form during the circulation of the 7-2 ED2.1 CDV to the NC
