Hi,

I am new in this field. I am a PLC and SCADA programmer. In my next application I have to collect some data from several remote PLC-a to SCADA. I want to put GPRS modem next to PLC and send data from PLC to some OPC server on PC with SCADA. I need AT commands to do that and do you know which modems has OPC server? What is the story with TCP stack. I heard that it it better to use modem with TCP stack.

Thanks in advance.
