The standard port for Modbus TCP is 502, but port number can often be reassigned if desired. The checksum field normally found at the end of an RTU packet is omitted from the TCP packet. Checksum and error handling are handled by Ethernet in the case of Modbus TCP. The TCP version of Modbus follows the OSI Network Reference Model.
