Procedure Upgrading Processor from PM510 to PM511 in AC450
is there any procedure please share it.

Without going in to every small detail here it's an very easy and safe upgrade.
You simply backup your system via DB & PC source code, and note down the dimensioning values.
Power of the controller and replace the PM510 with PM511.
You may remove the CI540 source code from the DB source code to avoid an error as it is no longer supported with PM511.
Also remove the CI540 (and the MB510 for the program card) from the rack as well
My recommendation is to create a new node in parallel in the Application builder for the New PM511 & latest 4.0 SW version and move the DB & PC source code there.
Then you power on, make a cold start, you dimension the DB & PC and you start to load, first the DB followed by PC application
If you use S100 I/O you also have to upgrade the DSCB 173A bus extender boards to DSBC174 (for redundant bus) or DSBC176
and you have to Activate the BE DB Elements elements for each existing rack, each DSBC 176 have to be addressed individually, see the manual.
If your customer is using SC520 carrier boards for MB300, they must be replaced (or upgraded) to latest version.
The SC520 version originally used together with PM510 CPU does not work properly with PM511
Then Diconfig and deblock programs, and save the new user disk files to target system, and finally take a new DUAP
In addition to what Jan-Erik wrote let me add few notes:
- more than obvious: always make DUAP backup before switching off existing system to have safe way back
- make printouts of settings in APP and MSTABS online commands in existing system
- make DUDBS with option - /OUTPUT that saves also actual values from DATs , AOCs, PIDCON/A constants , etc.
since AC450 logic can be developed in tricky way that some process constants are stored in DATs for reading only
- I suggest to do printscreens from all live graphics to be able to fill back process setpoints just in case
- in the new CPU , configure APP and MSTABS before DIMDB and DIMPC
