DanT Posted March 30, 2022 Report Share Posted March 30, 2022 Hi; You will need to set up the RS232 Com Port You can use the FB Protocol Function blocks to send the data string. Under Help, go to Examples, and then to Communications and look at the examples under FB Protocol. the Example V130_Send_number_and_string illustrates how to do this. In Help - search fb s library and then Communications Protocol Experiment, post your code with your questions. DanT Quote Link to comment Share on other sites More sharing options...
