Process Station
• Renew the resources assignment for the variables. This can be done manually or automati-
cally.
• The global system variables for the previously non-redundant resources, which have been
used in programs or pictures, still have the previous resource allocation in the Variables List.
The resource allocations must be changed to a possible new resource name.
These now undefined Identifiers are reported as errors in the plausibility check.
• In the hardware structure the individually exported blocks of the process stations must now be
imported into a redundant process station so that all the information on insertion and I/O com-
ponents becomes available once more.
When a rack-based process station PS is changed into a redundant FieldController AC
800FR, the I/O modules must be imported individually as a block underneath the CAN-
Master DNETP.
• Allocate the redundant resource to the redundant process station
• Plausibility check the project
