Joyz Posted September 22, 2010 Report Share Posted September 22, 2010 Hello! I have this small project where i use vision 120-22-R6C OPLC to gather information(battery voltage, pressure, water tank level) from fire truck. That is easy but the hard part is to send that data over gprs net to computer. I have intelligent modem so all i need to do is write some text to OPLC's COM port. I have made a program that uses Protocol Send FB to write data to COM. It works fine. But i'm worried about AT commands that modem needs to work. In COM Init FB i can write AT commands to start and configure my modem. If i use this Init FB, can my modem respond to my AT commands, like OK when i write AT in COM init? And can i use Protocol Send and Scan FBs to communicate with my modem with AT commands or is there easier way? Or can i write maybe C or C++ program and then use it as subroutine? Or can i maybe use data tables? If you could tell me some tips or otherwise point me to right direction, i would be grateful. Thanks for your time and effort.
