Hi guys I'm hoping for help. I want to test Classicladder's modbus slave and master over Ethernet (TCP). But I really have not much of a clue how to connect it all. networking for me has been connect the cables and let Ubuntu figure it out :) When loading classicladder I can specify a port number - default is 9502. What is this port number for? on the master I set the slave number by the IP number of the slave and can optionally set a port number (I assume 9502 is default) I tried this with a cross over cable direct between two computers and network manager seemed not to know anything about each other. I also tried this with a router between, Then of course I get IP numbers through network manager. Modbus Initializes, binds and then listens on the slave. It never returns from listening. I really don't know how to use the network tools (or if they are any help) to debug this. Suggestions ?
