MisterB.Ohio Posted January 8, 2021 Report Share Posted January 8, 2021 I have written software to receive data from an RS232 instrument using Port 2 (V100-17-RS4 properly configured) The issue is it does not receive a valid data packet. I have gone into INFO mode on the V700 and am able to verify that port 2 is configured for RS232 and can see monitor the received data. The packets are all missing the first 3-6 bytes of data. I have verified with a laptop plugged into the same cable that the entire packet is arriving at that point. Is there something obvious I am missing ? does there need to be a delay in the PLC software? Why would it drop the first several bytes? Oh and the data rate is not extremely high - 9600, 8, n, 1, no parity, no flow control. Thanks for any insight. Quote Link to comment Share on other sites More sharing options...
