MVP 2023 kratmel Posted May 7, 2020 MVP 2023 Report Share Posted May 7, 2020 Please post your protocol project. You can use Stream Protocol configuration embedded to Prot FB project in above topic. For online testing i use addon com port or ethernet card. It is really hard to configure protocol with only one PORT. Link to comment Share on other sites More sharing options...
Pradeep Mane Posted May 7, 2020 Author Report Share Posted May 7, 2020 Hello, Unfortunately we have only one com port ... Stream protocol used and according to data from RX monitor window of V350 data frame structure is 13 byte So i have configured 7 MI in stream configuration Attached code for your reference.. Thanks😊........... RS-232.vlp Link to comment Share on other sites More sharing options...

Message go to MI500-vector and then copy to MI50 buffer. MI50 buffer placed on screen. Refresh button only for test. 232_stream.vlp Link to comment Share on other sites More sharing options...
