This topic provides a summary of all changes which may need to be taken into consideration when changing from NIC 50-RE to NIC 52-RE.

...
At the NIC52-RE, the signal levels at the pins of the SPM/SPI interface to serial dual-port memory (i.e. pins 29, 30 und and 31) can amount up rise to 1.3 V at rest (for instance at start-up).
The exact value depends from on the design of the external circuitry.

Design your host system in such a way, that voltages up to 1.3 V at pins 29, 30 and 31 are logically interpreted as LOW. This must be assured by the design of your host system in order to avoid malfunction. The cause for this behavior lies in the difference of the internal design of netX 50 and netX 52 (netX 50 has internal pull-down resistors, netX 52 has internal pull-up resistors) and in the necessity of additional pull-down resistors (10 kΩ) in NIC52-RE due to compatibility reasons. |

...
If a PROFINET diagnosis is reported to the PROFINET IO Device protocol stack running on the NIC52-RE via the packet PNS_IF_ADD_CHANNEL_DIAG_REQ, the STA-LED remains on until a hardware reset occurs.
This behavior is contrary to that of the NIC50-RE, where the STA-LED will not react to a PNS_IF_ADD_CHANNEL_DIAG_REQ packet.
The behavior of the NIC52-RE is intended and correct. Other Hilscher PROFINET Devices operate in the same way.
Sending an appropriate PNS_IF_REMOVE_DIAG_REQ packet will switch off the STA-LED.
...
However, although being incorrect, the behavior of the NIC50-RE will not be changed in the near future.
Store configuration parameters permanently
A major difference between NIC 50-RE and NIC 52-RE is in storing configuration parameters permanently in flash memory.
Due to a limited number of write cycles on the flash memory, it is not recommended to use the application to change a permanent configuration.
We therefore recommend creating a fixed basic configuration using the NetX Configuration Tool and configure everything else during startup via the configuration register via Modbus.
Therefore, this function has been deactivated for the netIC 52, at product release.
