  1. Good Day, I would like to know how FX3U-64DP-M will keep cyclic data exchange running even if one of its active slaves is disconnected or shut off. Thanks.
  2. Hi everyone! I have this simple problem, but cant get over it. I have structured ladder/FBD Project and i use GX works2. As topic tells I use analog signal from field. Now, i need to compare this value X (from field) to Values X1 and X2, meaning if value X is between values X1 and X2 then M1 is true. Ok, but what function i need to use for this? Best regards, Juha.

    Hi all, Im new with plc programming and now I need some help. As topic says, I have FX3U plc and gx works2. Now, I need to tell stack heigth as positions by output. We all agree, that you can tell ten different situations when you have four outputs (Y1 and Y4 = position five). Is there any practical/ reasonable way to do this when you need use outputs. For example, is there any Functions for this, or? Best regards Ultra.
  4. 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
