I started this thread some time ago, now I am coming back to it.
I am purchasing the rs232-rs485 converter on tuesday, is there anything special about how it is hooked up. IE, do I need to use resitors or is it a direct connection?
Another question, I eventually want to hook up a radio modem, so that I can hook up to a landline and use the internet functionality of the PLC. Is there any you recommend or any that other users have tried.
As always cost is a concern, as this is more for my convienience than the customers.(its a long drive through traffic to the site, and the problems are generally easy to fix, it would be much nicer to be able to troubleshoot from my home computer)
I am using a T100MD2424.
Thanks.
