Extending LabVIEW to the Web Using the LabSocket System 1. When using TCP Read in Immediate mode, the Bytes to Read should be set to a large number such as 1024 because the function will read immediately FROM the number of bytes specified at Bytes to Read. However, I've found that there is a consistent time delay between sending the data over to Labview and the resultant data output for display. One cRIO is a server which writes 76 bytes long messages every 10ms (today, but can be anything between 1ms and 1s) using STM Write VI (so at the end it pushes 82 bytes long message in the TCP write function).

I really enjoyed it but haven’t got around to trying any of the concepts out yet. LabVIEW Interface for PCI-SpaceWire Interface Card. Modbus TCP. When using TCP Read in Immediate mode, the Bytes to Read should be set to a large number such as 1024 because the function will read immediately FROM the number of bytes specified at Bytes to Read. As in the serial case, we need to organize the data to conform with the MODBUS TCP frame specification. What is MODBUS? MODBUS is a commonly used industrial communications protocol. The code footprint pretty small and it gives you a good idea about how a TDP Server opens up a port, and then the TCP Client sends or receives data from that port. 5) If you select Labview, then Slection of Visa Port with respect to Bit, Baud Rate, Parity Bit, Visa Read and Visa Write is important.
