I am doing "module analog 1769-OF2 PLC rockwell" four types of data "Engineering Units ; Scaled-for-PID ;Percent; raw/Proportional data " data each type used when . differences between the four types .you can send through email ([email protected]) .Thanks

I suggest to take a look to the following Manual, page 4-7:

but I do not understand when to use each type

Well that's kinds up to you and your application.
I usually use engineering units.

but I do not understand the difference between the four types of analog data, used when you apply for help

tell us about your application, how your of2 is going to be connected to your devices, are you going to use 4-20 mA or 0-10V DC.

Raw/Proportional Data:
Gives you a wider range for slightly better resolution.

Engineering Units:
Represents the electrical output range.
0-10v ( 0-10000 raw data) 4-20ma ( 4000 to 20000 raw data)
Kind of a build-in meter.

Scaled-for-PID:
Use when using a "PID" instruction. The "PID" instruction will output 0-16383
raw data for it's "CV" No need to rescale it for the output card.

Percent Range:
When you the programmer like to see the output represented by a percentage value.

when to use each type of unit on

maybe you could explain what you trying to do with the analog signal ie: just read the value or control an output to a valve ect...

I think Mickey gave you a pretty good answer, and I don't think you are going to get a better answer at this point. It depends on the situation and the design goal. We can't really give you a specific answer without a specific question. If you have a specific question or situation, then post it.
