"b) On expiration of the timer the wanted action shall be activated and a response shall be sent to the client."
The action depends on several conditions: the value of Behavior, Local/remote, etc.
Proposal
Add the conditions that have to be met before the action can be activated:
"b) On expiration of the timer the wanted action shall be activated (if the conditions LNBeh = on or test AND LDMode = on or test AND Loc of LN = false AND Loc of LLN0 = false) and a response shall be sent to the client."
In general: the State Machines for control should reflect these conditions as well ... may be it would be sufficient to state this at the beginning of clause 17 (Control). These conditions have to be met in any case.

Status
All conditions can not be displayed in the state machine.
Anyway, Logical Node Behavior as well as Local/Remote or interlocking for instance have to be mentioned. The clause 17.1 shall reflect the purpose of [Test OK] and [Test Not Ok] with a list of test examples.
