  1. PLC->OPC->Labview

    OK, so there are no ways to decrease the communication speed. Is it perhaps possible to communicate arrays of integers in stead of single integers. Is it possible to decrease hand-shaking time by communicating arrays of values. Or, is an Ethernet module the only option for increasing the communication speed?
  2. PLC->OPC->Labview

    Hi, I have been trying to communicate between a PLC(Mitsubishi FX3U) and Labview (using Data Socket) through a KEWserverEX OPC-server (using a RS232C COM Port cable). I have been successful at that by using baud rates ranging from 9.6kbits/s to 115.2kbits/s, with average reading time into Labview ranging from ~40ms to ~10ms (of course depending on baud rate) per value. However, this is too slow for our purposes, and we need it to be in the area of 1-3 ms per value. Are there any tricks to decrease the reading time between the PLC and Labview, or do we perhaps need an ethernet module? Kind regards Bjørnar
