1. From the Gallery, export the ML_PID
compound. The analog input, input
function, PID, alarm, display, tune list, and
output blocks appear in the workspace.
This must be loaded within a Loop
Compound in a MOD 30ML.
3. Open the Display (DISP) block and
position the cursor in the Display Tag field
showing PID-100
Do not confuse this with the Block Tag
field at the top of the menu. The Block
Tag field serves only to identify the block.
Each display must have a unique name;
this may be the same as the block tag for
easy reference. Display blocks in pre-
defined compounds are usually re-
named by the user according to the
specific application.
4. In the Display Tag field, type in a tag
name of your choice.
It is often helpful to make the Display
name the same as the loop tag name,
such as LIC-100.
Enter the tag name again in the Initial
Display Data field for Line 1, enclosed in
double quotation marks. For example,
“LIC-100”. Or you can type the keyword
DISPTAG (no double quotes).
Any text enclosed in double quotes in the
Initial Display Data fields will be
displayed as entered.
5. Close the block using OK
