Function Notes

Experion PKS Series A Fieldbus Interface Module User's Guide

The Control Selector function block accepts input from up

to three control signals and selects one for output based on

the SEL_TYPE setting of High, Middle, or Low. A functional

schematic of the block is shown in the previous illustration

for reference.

All inputs must have the same scaling as OUT, since

any one can be selected for OUT.

Supports Out of Service (OOS), Initialization Manual

(IMan) Local Override (LO), Manual (Man), and

Automatic (Auto) modes.

If an input has a sub-status of Do Not Select, it will not

be selected.

Three separate back calculation outputs

(BKCAL_SEL_1, 2, 3) are available - one for each
