Telepace studio

[tharun]

Hi all,

         In my telepace program, i want to include the GPS as an input. However i'm not sure how to get the ASCII value(string) and then process them. Any ideas on how to do it.

Thank you.

Hello Tharun,

Unfortunately this can't be done in Telepace Studio as there are no standard ASCII drivers. Stating that, this can be done in a custom C/C++ program when the serial port settings are set to NONE in the Telepace Studio project. Perhaps someone else here has an example for this sort of thing, but I do not.

Hi tharun,

I'm afraid this can hardly be done via TelePACE ladder logic.

However it's rather easy to do in a C/C++ application: you'll need to set up the serial port accordingly, read the serial port buffer to an array, and take it from there.

I've had good results with implementing custom serial comms protocols on the SCADAPack, so the GPS is doable - there are plenty of code examples when it comes to parsing the NMEA data. And the fact that you probably won't have to query the device, rather just listen on the port, makes the job 50% easier.

If you have any questions, feel free to ask them here.

Later.
