looking....

Searched for the Tag in the 500 project, (PHECoolControl\perc_open) N19:85 for the cold side, and Tag (PHEHotControl\perc_open) N19:39 for the hot hot side. Neither one was found.

N19 search result in the 500 project

Go to help, SCL Instruction Help choose PID. then click on
PID Control Block Word 16 is Control Output 0-100% So The Tag N19:85 is coming from CG1 PID whose address is N19:69 + CV = word 16 so N19:85

PHE COOL PID is N19:46 + 16 = N19:62 So Looks like Tag in HMI should be addressed to N19:62

Each PID uses 23 Words as you can see Control Block Lenth = 23

I believe Something about this is not right.
How can the Cool percent control and the CG1 control have the same N19:85 tag from the PV. 85-23="62" maybe that's what they meant to program in. right?

How can I get that excel tool, or did you make that?

 

[cwal61]

I made it using the fill box on the cell. Point mouse to bottom right corner of cell. Mouse will turn into a + sign Hold down left mouse button and drag down.

you need to change Cool percent to N19:62 in Factory Talk Tags and Leave N19:85 on CG1.
