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. |

These are available in the chapture chapter "Serial Shift IO Interface", of the netIC - Design guide and User manual.
...
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.
...
Due to a limited number of write cycles on the flash memory, it is not recommended not to use the application to change a permanent configuration.
We therefore recommend to create 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.
However, since Firmware V2.3.0.0 storing a configuration into the flash has been activated again.
To use this function, beside the appropriate Firmwareversion, a 2nd stage bootloader with V1.6.0.0 needs to be used inside the NIC 52-RE.
V1.6.0.0 is used in production since April 2019.
The steps for storing a fixed configuration to the flash memory, is nearly the same as for NIC 50-RE:
- Write all configuration parameters to the corresponding registers using function code 16.
- Set the CLR_CFG (Register 1999, Bit 6) flag within the command register to clear the configuration parameter in the Flash memory.
- Check the status of the System Flag (Register 999) until the flag FLS_CFG (Bit 7) has been cleared.
- Set the STR_CFG (Register 1999, Bit 7) flag within the command register to store the configuration parameter in the Flash memory.
- Check the status of the System Flag (Register 999) until the flag FLS_CFG (Bit 7) has been set again.
- Set the INIT (Register 1999, Bit 4) flag.
- The netIC now starts with the new configuration parameters.
With netIC 52, for step 2 the CLR_REM_CFG Flag (Register 1999, Bit 12) needs to be set to clear the configuration parameter in the Flash memory.
