Is there a way to update software revisions in redundant 800F controllers without shutting system down?
We have an installation with redundant controllers and need to update both the operating system on the PCs and the software revision on the redundant controllers. We can't shut the process down to do so. There doesn't seem to be a "built in" way to do this update.
Our guys have tested placing the I/O in hold and removing from the bus, which seems to work, but I hoped there were some other thoughts out there.
