Multiple CPU improvements and information on the functional state

This firmware update is related to the following CPUs:

• CPU 314C-2 PtP
• CPU 312C
• CPU 315F-2 DP
• CPU 312
• CPU 313C-2 PtP

Improvements

Indirect addressing of an "ARRAY of UDT" element with a temporary variable does not highly sporadically yield a CPU stop anymore

The CPU no longer highly sporadically enters the defective state when calling up the block hierarchy from the TIA Portal

The "Name of Station" element can also be assigned when the SIMATIC Micro Memory Card is not inserted or empty

If an incorrect message is forwarded by a communication partner, this can always be rejected or acknowledged as negative

Important notes

STEP7 V5.5 or higher is required for the configuration of these CPUs When using the TIA Portal, V12 or higher should be used, where possible.

iMap V3.0 SP1 or higher is required for the CBA configuration.

Configurations with earlier STEP7, iMap, and TIA versions are compatible with later releases.
