upgrade application builder
we need upgrade application builder4.2 to 800xA and change citect to abb hmi . how we upgrade that without shutdown plant ?
If the PROM is supported - No problem. The controllers do not have to be stopped. Nothing changes in the AC450.
Follow the upgrade instructions for upgrading application builder. Make sure you have the .TED and .PED files for any special AC450 libraries - you will need these to upgrade Function Chart Builder.
If the PROM is not supported - then normally 95% everything works OK - typically some system status displays do not work on 800xA. You need to upgrade the firmware sometime, but the system 800xA **should** function normally. However, you should confirm with ABB supportline that your specific firmware revision does not have any faults that can stop the 800xA system. There is no problem with upgrading Application Builder.
