The firmware V5.1 has no new functions, but only corrects problems.

use v5.0 in HWConfig
or
see upgrade firmware to 5.3

Important:

If you are making system changes by means of CiR (Configuration in RUN), we recommend not to use firmware update V5.2.
Memory bottlenecks can otherwise occur in the case of large I/O quantity frameworks.
Please continue to use firmware V5.1, available under entry ID 15121256.
The response described for firmware V5.2 is expected to be corrected by Feb. 2009 with firmware V5.3.
