Extended improvements and features download for CP 443-5

Improvements

• The firmware contains a robustness level adjustment to avoid bus failures which may be caused by suboptimal PROFIBUS physics. The robustness level adjustment becomes active when a retry limit of 5 or higher is set
• The highly sporadic behavior resulting in a system error (all LEDs flashing) when activating/deactivating PROFIBUS DP slaves now no longer occurs

Important notes

The CP is released for operation on:

• SIMATIC S7 CPUs from firmware version V4.0
• SIMATIC S7 H-CPUs (high availability system) from firmware version V4.5
