How to check Ethernet Configuration (for Industrial Raspberry PLC)

The?industrial?Raspberry PLC has two Ethernet ports, eth1 and eth0. The Ethernet port controller is based on W5500 IC and generates the eth1 interface, while the eth0 interface is automatically generated by the Raspberry Pi 4. In the Raspberry Pi PLC family devices, W5500 IC communicates by the Raspberry Pi 4. In the industrial Raspberry Pi PLC family devices, W5500 IC communicates with the Raspberry Pi 4 via SPI1 bus. By default, we have a virtual interface with the IP address 10.10.10.20 called eth0:1. Likewise, the eth1 has a virtual interface called eth1:1 with the IP address 10.10.11.20. In case your Raspberry Pi industrial PLC has some Ethernet troubles, check out the following post.
