W5200 to Rockwell PLC

i need connect to rockwell PLC via CIP ethernet. any sample code are available ?
w5200 → Ethernet CIP → (1756-ENBT)PLC

sorry, WIZnet doesn’t have any reference codes for PLC and W5200.
However, in the case of a new project, would you use W5500 instead of W5200? we don’t recommend to use W5200 for a new project.
Just for your reference, I found out https://www.industrialshields.com/support/help/ethernet-plc-3/m-duino-ethernet-21 from googling… is it useful?
