4Ć168 ICP Configuration

Original Ć June 1990CE4.2:CL6211

4.6 IAC/Computing Discrete ICP Point

This section of configuration defines a discrete ICP. A discrete ICP is a

set of discrete values used in operator interface displays or by certain

functions in the FST of the controller.

Device v Ċ The device tag name of the controller that is currently being

configured up to 12 characters in length.

Index Ċ The number of this ICP within the controller. The number of

available ICPs for each controller are listed in Table 4Ć9.

Table 4Ć9. Valid Index Numbers for Discrete ICPs.

Controller Quantity of ICPs Valid ICP Index

Computing 4 9 to 12

2-Wide IAC 6 9 to 14

3-Wide Discrete IAC 6 9 to 14

3-Wide Analog IAC 12 9 to 20

4-Wide IAC 12 9 to 20

Description Ċ The description of the point may be up to 16 characters

in length. The first 12 characters will appear on the faceplate display of a

console on the line immediately below the point tag. All 16 characters

may be used on a custom display. Any printable character may be used

in the description.

Strategy Ċ The strategy field is a 12 character text field that can be used

to help group points together. For example, if the plant consists of a

boiler, a reactor, and a tank, the strategy field of each point could be set

to either Boiler", Reactor", or Tank". This data is not checked or

processed in any way, but points can be sorted by the strategy field.

EU Descriptor Ċ Units used for reference if the following engineering

unit conversion values are used for scaling by functions in the FST.

High Scale Value Ċ The value that defines the upper engineering unit

end point to be used for scaling in the FST. Any valid floating point

number is allowed, however, it may not be the same as the Low Scale

Value. This tuning parameter can be changed using DDP #2, EU 100%.

Low Scale Value Ċ The value that defines the lower engineering unit

end point to be used for scaling in the FST. Any valid floating point

number is allowed, however, it may not be the same as the High Scale

Value. This tuning parameter can be changed using DDP #1, EU 0%.

No. Ċ A read-only field displaying the number of the discrete register

within the ICP. There are four sets of discrete values associated with

each discrete ICP.
