PLCHobbyist Posted January 29, 2012 Report Share Posted January 29, 2012 Hello, I want to use my V120-R1 to read and display the serial data sent from my Qkits VK011 thermometer. I know that i have to use the "Protocol scan" FB but i don't understand how to configure it. There is 2 COM ports on the PLC; does these ports correspond with COM 1 and COM 2 or they are assignable? If yet, how can i do that? Here is the data that came out from the VK011, as it appears on a sniffer program: 0A0D QKits.com0A0D 0A0D 0A0D Sensor 1,+22.50 , DegC, 0A0D Sensor 4,-02.13 , DegC, 0A0D Sensor 1,+22.50 , DegC, 0A0D Sensor 4,-02.13 , DegC, 0A0D Does somebody can help me? Thank you! Quote Link to comment Share on other sites More sharing options...
MVP 2021 Joe Tauser Posted January 29, 2012 MVP 2021 Report Share Posted January 29, 2012 In Visilogic- Read the Help on the COM INIT block. You'll want to use COM 2. Then read the Help on ALL the Protocol blocks. You will be using at least three of them. Then look at Help->Examples->Version 900->Project Examples->Communications->FB Protocol->V130_Display_String_from_Hyperterminal.vlp. The V120 and the V130 are the same at this level. After you've spent some time looking over the Help and looking at the examples come back with any questions. What you're looking to do is fairly easy after you understand how the pieces work. Joe T.
