Status Object

The Safeguard Status Object is an MMCX object with configured reftype = 38 in
the Safeguard controllers. In the Control structure of Plant Explorer this object type
is named MMCX3.
When a Safeguard system is created in the Control Structure and an upload is
performed, all objects are included in Extended Process Object and Local IO (as
for AC400 controller types).
The Safeguard Status Object (MMCX3) is located beneath each of the branches of a
Safeguard controller (see
beneath the virtual Safeguard controller object. Each branch of a dual system has its
own status object which can be viewed and displayed individually. The operator can
obtain the status of 'Side A' and 'Side B' independently.
The Safeguard Status object can also be added to the Functional Structure. This is
done when a Status object presentation is used in process displays (see
because it is easier to find it in the Object Browser of the Graphic Builder.
