Status Point Output (OP)
OP is the opposite of PV, that is, OP represents values that can be changed by an
operator or by another component of the system when performing supervisory
control. The OP of a point can only be changed by an operator if the mode of
that point has been set to “manual.” (For details of point modes, see “Status Point
Mode (MD)” on page 125.)
For points in your system that are to be used in controlling a process or value,
you need to define the available states that can be controlled.
For a status point, you can define up to four output states, which correspond to
four of the input states for that point. In the valve example, you might define
CLOSED, and OPEN as the two output states.
Status Point Mode (MD)
The mode of a status point is used to determine whether or not an operator is
permitted to control the output value. The two most common modes are:
“manual” and “automatic”.
MD can also be used with an alarm transportation algorithm to trigger an
additional output under alarm conditions. See “Action Algorithms” on page 194.
For information about control modes, see “Control Modes” on page 153.
