If there is no driver for CODESYS fpr direct accessing the I2C1 bus you could easily deploy another container with Node-RED including a node for the NVRAM. With this container you could realize a Modbus TCP server to NVRAM function. Then from CODESYS you could add a Modus TCP client with the IP address of the second container that gives you read/write access to the NVRAM.
