Expanded OrionLX LogicPak Functions

PUBLISHED ON Jun 23, 2009

The OrionLX LogicPak module has been expanded to provide five preconfigured logic operations:

Or
Performs the logical Or operation on two or more specified discrete inputs (inputs that can have the value 0 or 1) and stores the result of the operation in another data point.

And
Performs the logical And operation on two or more specified discrete inputs, and stores the result of the operation in another data point.

Negate
Performs the arithmetic Negate operation on a specified analog input, and stores the result of the operation in another data point.

PrimarySecondary
Provides redundancy through automatic switchover between two identical input points. For this purpose, the same field input must be wired to two different devices, such as meters, relays, or PLCs. The devices can be of the same type, or different types, as long as the point is reported the same way in terms of scaling range (analog points) or normally open/normally close (discrete points). Orion must be set up to poll both devices. The PrimarySecondary module then monitors the on-line status of the identical points from each of the two devices. If one of the two points goes off-line, e.g. communications to the respective device is interrupted, the PrimarySecondary will automatically switch over to the “mirror” point obtained from the other device in order to continue to report a live value. During the transition, SCADA does not see any interruption or detect any change. As many “point pairs” as needed can be set up for the PrimarySecondary module. A point pair can be either digital/binary, or analog, but cannot be mixed types. If both points in a pair go off-line, then a specified “offline” value can be assigned to the PrimarySecondary point, if desired.

LocalRemote
Provides local or remote access to a particular output control that is to be executed. One of the four input points corresponding to the four physical inputs on the back of the Orion5r/OrionLX is used to control whether or not a particular output control’s execution is allowed (remote mode) or blocked (local mode). When the corresponding “logic” output point is executed, the execution will only pass through to the actual output point if the specified input is high.

All LogicPak operations are set up with drag-and-drop and without any scripting.
