Hello, I recommend start here (link): Serial communication with Hyperterminal PC Check web for general info about serial communication. After check documentation of device to which you need communicate, you'll know what messages you need exchange. I recommend use that Terminal PC application as some kind of simulator because you then can check messages outgoing from your PLC, maybe then repair your code as you need. Simply, all depends to that system of exchange data, maybe you need for first ask to device with some message and then it send back to you some answer, or device send cyclically (with interval) data and you need only listen on port. Update: you can of course download Step7 TIA V13 SP1 manual and check exactly what parameters need to be set, also inside TIA when you click on instruction/block with F1 some info is available. |

Hi Duris_I, Thank for your help! AIS AtoN is one device Aids to Navigation. Now, It is received messeage from datalogger. I want to replace datalogger by PLC, so I need connect to send message from PLC to AIS AtoN. But In AIS AtoN, I have seen 1 RS422 / RS485 Port to use communication with datalogger. I read manual and topic "https://support.industry.siemens.com/cs/ww/en/view/45057335". But I dont know How to send message to AIS AtoN |
