This 'What is PID' video is the 3rd in the Closed loop system video series. This one introduces the PLC PID using a RSLogix 500 tutorial and pressure control system example of applying the PAC - PLC PID controller. You'll learn design of PID controller using PLC in the PID instruction ladder logic example basically the same as Studio 5000 PID instruction (example uses memory address instead of tags).
Now that you learned whats PID, if you want to learn PID controller tuning, see

Output is current or voltage signal? O6:1 output

Like it shows, 4-20ma. But would be the same if you wanted 1-10v, you just change card on 500, setting for card on 5000. Logic/function the same, scale/setting may vary depending on application.

How did you come up with the range of 3277 to 16384 ? Is that always the same or depends on the A/D input card? What would be the best way to understand what range has to be used for different cards and transmitters. Thank you

It is a computer numbering standard and standard among all A/D. As the max value 32767 is arrived at by being the maximum number that can be stored in a 16 bit integer block of data. (In computers its always been base 16 ... 32, 64, etc., later 32 bit word sizes (base 32) become more commonly used, but it is the same 16 bit max. ) The limits set in video (3277-16384) where just decided by programmer for specific application in the example. You may have a 40ma sensor that manual indicates uses max 32767 to -32768 but the programmer may chose to only use a smaller range. (They just cant use a larger one than device manual indicates. Most will be that 'magic' number 32767.

@@Bin95 Thank you for the reply. But shouldn't be a common rule to determine what range has to be selected and why? On other words, what's the benefits of shortening the range? What if we use the whole range -32768 to 32768?

How did you come up scaled min 6242 and scaled max 31208 ?

The programmer comes up with the range based on sensor specs and application. The sensor documentation is the place to start, then deviate if needed by the application. As long as you have the whole scale/bandwidth of the sensor or greater, the programmer sets the trip points according to the application, independent of the sensor scale.

pls can we perform PID simulation in RS logix500 without actual real input and output. tried it actually don't know if am doing something wrong the PID isn't giving me any output pls I need clear explanation thanks

You will need to write some logic to simulate a varying analog input if you are not going to use a real input signal. Then your PID will output.
