SUPERVISORY MESSAGE BLOCK
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.
Attribute not writeable 15 Message not accepted because that attribute is
never writeable.
Block not present 17 Message not accepted because the destination
block, although legal, is not present in the
destination instrument.
Invalid mode 18 Message is not accepted due to the present
MODE of the destination BLOCK, LOOP, or
instrument.
Invalid write by configuration 19 Message is not accepted because the
destination attribute is not writeable in its
configuration. Likely reason: an input attribute
that is configured as an LSP.
Instrument state in transition 22 Message not accepted because the destination
instrument is currently changing state and cannot
process the message.
Invalid set-point state 23 Message not accepted because of the
destination block’s current value of
SET_POINT_STATE.
Invalid remote/local status 24 Message not accepted because of the
destination block’s current value of
REMOTE/LOCAL_STATUS.
Invalid message 26 Message not accepted because the message
code is not valid.
In HOLD state 31 Message cannot be accepted because the
destination instrument is currently in the HOLD
state.
