I know this is an older thread but something I have seen before is if the machine can make a socket connection you can use software from p1ge0n.com to send emails and sms messages. So basically the machine connects to the p1ge0n software running on a PC via a socket and sends an ascii string with emails, phone numbers, and the message then the p1ge0n software takes care of the rest. If your controller cant do sockets and you have an extra relay, you could get a cheap plc like an AB micro 820 and have it read the relay status and then have it connect to the p1ge0n software when the relay changes. There are fancier solutions out there that are much more complicated and $$$$ but like the simpler solutions. KISS Keep It Simple Stupid
