On Page 0000059 the 2nd paragraph says:

"Because Methods may control some aspect of plant operations, method invocation may depend on environmental or other conditions. This may be especially true when attempting to re-invoke a method immediately after it has completed execution. Conditions that are required to invoke the method might not yet have returned to the state that permits the method to start again."

In the case of the LAST SENTENCE, what should the Server do/return if it cannot invoke the method? Should it:

(a) return GOOD and simply ignore the request since the conditions have not reached a state where the method can be invoked again.

(b) return an error code stating the method cannot be invoked yet, perhaps Bad_TooManyOperations since it is listed in Table 62 (along with Bad_NothingToDo). Or, seek an alternate error code like Bad_InvalidState?
