Type updating in RUN (TCiR, Type Change in RUN)
In connection with the CPU 410 process automation (Firmware V8.1 or higher) and PCS 7
Version V8.1 or higher, a type update in RUN mode is supported. This makes it possible to
update the instances and download them to the CPU in RUN mode after changing an
interface at the block types.
A library can be updated with the TCiR function without having to stop the AS. The TCiR
function does not claim to be able to migrate/update the project (the process cell) in Run.
