This state can occur temporarily with CiR processes. It is only necessary to take steps if
the error persists.

correspond to the configuration (redundant/non-redundant) or the DIP switch setting of the
redundancy mode does not correspond to the configuration
● If the associated FF device is not available or with regard to configuration has an FF address
that does not match its "Physical Device (PD) Tag".
