  2. FX3U-232-BD

    Hello, everyone. I have FX3U-32M PLC with expansion board FX3U-232-BD. I successfully can read and write program through programming port (RS-422 mini-din 8pin) at GX Works2. Now I am trying to connect through FX3U-232-BD, but I can’t. I have a task controlling PLC with OPC server. And I must to connect through FX3U-232-BD, because to the programming port connected touch panel. What should I do, to do it correct. At the program I see, that H81 is writing to the D8120 register. Which means that channel 1 settings is: 9600 speed, 8 bit, no parity, 1 stop bit. But I can’t connect with this settings. Cable which I use: PC PLC 1 1 2 3 3 2 4 6 5 5 6 4 7 NC 8 NC 9 NC I am new in this type of PLC, and I need fast solution. So you are my last hope. Sorry for my English.
  3. Non-volatile memory GX Works2

    Hi all, Im trying to figure out how to create non-volatile memory tags in GX Works 2 (using a FX3U controller), so that the values stored in the D registers won't keep zeroing out every time the controller powers down. Does anyone have any helpful tips on how this is done? Thanks
  4. FX3U Programming Manual.pdf

    The FX3U Programming manual is a 995 page secured pdf. You cannot copy-paste from a secured pdf. I reprinted the manual with Soda Pdf and OCR'ed it with Acrobat, using no downsampling. So now i have an unsecured searchable pdf. https://www.dropbox.com/s/3ad2ceclphla0z0/FX3U%20Programming%20Manual%20OCR.pdf?dl=0 Cross-platform and free software used: Pdf Split and Merge Basic and Soda PDF: Combine pdf pages Dassault Draftsight: edit and print autocad dwg and dxf, with 3D and scripting support CloneZilla Live: Create and restore a server/ computer image
  5. 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.
  6. 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.
  7. FX3U_GXWORKS2_BINARYCODE_BY_OUTPUTS

    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.
  8. 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
