TCP 502  Modbus TCP - MBTCP, MNET products

TCP 44818 Ethernet/IP - EIP and DFNT products

UDP 44818 Ethernet/IP - EIP and DFNT products

TCP 2222  Allen Bradley CSP protocol - Fieldserver

TCP 2000 Encapulated Modbus TCP - Typically used for Modbus TCP through serial to Ethernet media converters with MBTCP and MNET products.

TCP 20000 DNP3 over Ethernet - DNPNET, DNPSNET products

UDP 20000 DNP3 over Ethernet - DNPNET, DNPSNET products

UDP 47808 BACNET IP - Slotserver and Fieldserver BACNET products

UDP 1024  Fieldserver discovery service - Slotserver and Fieldserver products
