Calling remote dial-up modem used for programing plc.

Mar 31, 2009 9:17AM PDT

What are my options for dialing a remote dial-up modem from my laptop when there is not always a phone line availible is there a way to do it by using a wireless broadband card or is there a program to do via the internet. I'm using Window's Xp and the comunication software is RS Linx and I can configure the com port.

I've done some stuff like this and it's too technical for me to tell in the one paragraph that I'll write about it. But it is very doable. If your staff can't get this done, look for some other people that know how. There are solutions to this but the only time I found no solution was when the client restricted the solution. So there it is. It can be done.

In the early 90's my co-designer and I were downloading programs to the AB PLC5 family. While validating a build at one of the remote sites I noticed an indicator light going on and off intermittently. After disconnecting the phone lines to the modem, the false indication ceased. An unauthorized program change was also noted before I was laid-off. I told management I thought a Cracker was at fault. I was told I was crazy. About 3 years after being laid-off, Contact with my prior co-designer divulged that management mysteriously decided to disconnect remote modems and send personnel from CT to FL to download programs locally. You shall have added insecurity if you utilize the airway.
