Setting the IP address via registers to be non-volatile
The IP interface is initialized by the settings in the configuration memory
during the boot process.
The following non-volatile settings can also be changed via registers:
IP address
Subnet mask
IP address of default gateway
I
Overview over the configuration memory registers:
Register
Description
101200
IP address
101201
Subnet mask
101202
IP address of default gateway
101299
Saving the settings (0x77566152)
To change the configuration values to become non-volatile, proceed as
follows:
Step
Action
1
Enter the desired configuration into one or several registers within the
range from 101200 to 101298.
2
To have the device take over the values, you must enter a password.
For this, write value 2002149714 (0x77566152) to register 101299.
3
Wait for the device to write value 0 into MR 101299.
The save process is now completed.
4
Boot the device.
Result:
The settings are completed. Communication is possible again.
Important note:
The EEPROM data on the backplane module allow for 100,000 write cycles.
We urgently recommend the following workflow:
First read out the value, then compare it. Only if the value has changed, start
writing.
