Modbus TCPDealing with Ethernet and Modbus TCP:‣ User needs to understand subnetting and IPaddressing‣ Using Modbus TCP across subnets requires theuse of IP gateways. . Gateway address setting inIP configuration becomes important‣ Modbus TCP uses port 502 to communicate.Important if punching a hole in any firewall forcommunications.‣ Modbus TCP uses TCP/IP connectionmanagement to allow multiple communicationsconnections making multiple masters on aModbus TCP Network possible.
Modbus TCP –Troubleshooting onEthernet‣ Use a good Ethernet capture tool such as Ethereal(free at www.ethereal.com)‣ For testing, , Modscan32 or similar is recommended(www.win-tech.com). Use to emulate a Client on thenetwork and test communications.‣ Know the network layout, , including all subnets,Modbus TCP devices, routers, and firewalls whichcan influence communications. A detailed networklayout diagram is essential.‣ IP Addressing – does your device‣ Support IP addressing in conjunction with variable Unitidentifier (Node_ID(Node_ID)?‣ Fix the unit identifier and work with IP addressing only?‣ Know which variant involved - FieldServer will need to fix itsNode_ID to the correct address if the latter is in use.
