8-84

Locked state 12 Message cannot be accepted because the

destination instrument or LOOP is in the locked

state.

Invalid parameter 14 Message is not accepted because the data value

is out of range for the destination attribute. Or,

the number of bytes sent as data is

unacceptable.

never writeable.

instrument is currently changing state and cannot

process the message.
