Upgrade AC800M CPU and keep Compact Flash
Is it possible to replace CPU PM851 for PM860 using the same Compact Flash backup? In short, just replace CPU and move Flash from old to new, get production working without using Control Builder, so that the SW is loaded from flash prepared for PM851?
CF card is generally used to, backup program and some variables. Also it is used to backup firmware and configuration image of CPU. If your CF card inluces old CPU firmware and configuration you can not use it for newer one.
So you have to download new datas to CF. For this aim right click to Controller and then choose Download to Removable Media and Load Firmware to Removable Media.
Hope this helps you.
First you need to know for what purpose the Flash card is used
1. To retrive the Log when a crash occures
2. If it used as the program backup, any change in the logic or configuration need to be updated again.
1 st case you can use same for both controllers
2 nd case you need to update the controller flash since you are changing the controller type
