  2. Entering multiline string in FTView Studio

    It is not about how the text looks on the display. I need to insert the line terminator into the string tag, while entering text from the display. There is no Ctrl key on the PanelView Plus7 display keyboard.
  3. Today
  4. Ctrl + Enter for static text but you probably knew that. I'm guessing you would like to control where a String tag will start a new line? It appears, the multi-line will be automatic depending on the size of the String Input Enable object. 
  5. How to calculate square meters with cj1m?

    I didn't look at the file you provided but I must ask, are these values accurate? Do you have the dimensions of the product? Can you multiply the length * width then multiply by the number of pieces? 
  6. Is there a way to enter multiline string in "String Input Enable" object? The tag monitor in Logix Designer allows this by inserting $R$L, but how to do it from the PanelView display?
  7. I don't have the Mitsubishi software handy to show an example but I'll explain. The counter's value can be a static value that once programmed, it will never change. If you use a D register for the value, then the set time can be adjusted, or changed. For example, from an HMI. 
  8. CPU BUS UNIT ERROR

    I got a similar case for a CJ2M-CPU31 unit, there were " 0x0200 CPU BUS UNIT ERROR 0 " from time to time. The unit would gave all 7-segment display off after power on when the Ethernet was connected. This error also found in the EIP unit error logs "0x0601    0x8000    CPU Bus Unit error". So we swapped the EIP board with another unit, the errors gone forever.
  9. Hello everyone, once again I come to ask for your wise help to learn how to do it: How to calculate square meters with cj1m. Let me explain: I have a cj1m-cpu22 to which an hmi ns5 is connected and they asked me to make a screen that would display the number of total pieces produced, the pieces per minute and the square meters produced, which at the end of each shift will be reset. by the operator after taking note of them. I leave the network I made to see how the counts of pieces per minute and total pieces are done Thank's for help.   contagens.zip
  10. Well, I was just curious, nothing more, and no, I won't do it, you can be sure of that, as I said before, I don't know how and I don't think I have the knowledge to do so. But it's very interesting, yeah. ;)
  11. Hi, What is the idea to store counter value into D register or M memory address in mit plc?

  13. RS485 custom serial message (start bit, CRC...)

    Is there an easy way to swap out that sum check code with cyclic redundancy check? That would just be convenient... Because then i can define my header and terminator as my DLE STX and DLE ETX respectively and all the stop/start bits and parity are there with CRC concluding it in one go. Otherwise I have to turn off header and terminator, and send DLE as one RS2 ladder logic command, STX next, etc etc, then calculate CRC and send those over RS2 command. which is fine, just more tedious.
  14. RS485 custom serial message (start bit, CRC...)

    Hello! That is a huge relief. RS485 is asynchronous so, as you suggest, the start bit is default. Ok that solves my issue. As far as handling CRC, I may or may not return over that one. I think I can just have it calculated in ladder logic and sent with no issues since the start bit is implied. thanks!
  15. RS485 custom serial message (start bit, CRC...)

    Serial ports generally do not permit configuring the start bit.  It's always there.  (Strictly speaking, it's there for any asynchronous channel, which is all that most ports allow.  Synchronous serial doesn't have start or stop bits.)
  16. Hello hello, may I have your experienced advice with GXworks3? I have to write an RS485 protocol into the FX5UC mitsubishi PLC with GXworks3. I have a guide of the protocol so I have all the information. I attached an image from Section 6.7 of the FX5UC serial communication guide (one of the GXworks3 e-manuals) and it shows a message that is quite similar to mine. If I am not mistaken, a single RS2 ladder logic block will do that full message. The other image shows some PLC configuration where I can define those headers and terminators, and sumcheck. Fairly straight forward.   Here's where it gets a bit foggy. For my needs: Each character of the message (DLE is a character, STX is a character, data is treated as all one character...) needs a start bit, 8 data bits, odd parity, and one stop bit. So DLE needs start bit, parity, stop bit, so does STX, and my data chunk, etc. Correct me if I am wrong, but I'll probably have to turn off header and terminator in the PLC config, and send those characters individually so the parity and stop bits are added. But what about that start bit? The config image I sent shows that I have no start bit options. I can't just add a header that is 1 bit (also correct me if I am wrong). It seems to want to send a full 8 bit header even if its all zeros and a 1 (00000001) which won't work for timing reasons. And because I will have to send each character individually, then I have to generate my own CRC bytes. But maybe I can handle that if you show me how to do some manipulations to add in my start bit.   So to start off, how would I add a start bit using ladder logic? The RS2 command does not seem to give me that type of access. Section 6.7 of the FX5UC serial communication guide (one of the GXworks3 e-manuals) nicely explains how to do the communications over RS485 but again, no start bit or CRC options.
  17. CC-Link AD/DA IQ-R

    Hello everyone, I am studying Mitsubishi R-Series PLC with GXwork3. I don't really understand communication using CC-Link. Below I have the module configuration that I use. My hope is that the Digital operation value of the AI module is stored at addresses D0-D32. and I sent AO to address D100-D132.  can someone guide me to give me an example of how to set parameters and create a program. thanks you
  18. Port 0, parameter 571 is "Preset Speed 1" and its default value is 5. Since this sounds like a new installation, it's a fair bet that value hasn't been changed. Check the rest of your configuration to see if any of the drive's pre-set speeds are active.  One of the first thing I do when troubleshooting speed control problems is put the drive in manual and see if it will respond properly to speed commands from the HIM. If so, the problem is likely somewhere in the drive configuration or Logix code. Sometimes I find that someone else has already put the drive in manual, and that's actually the problem. Assuming the drive runs properly from the HIM and we therefore suspect drive configuration issues, check the following: What is the Speed Reference for the drive set to? This should be Port 0, parameter 545, "Spd Ref A Sel", and the default is Port 1, the HIM. If your intent is to control speed commands from a Logix controller on Ethernet, the "Internal Value" column of this parameter should be set to 877, which is "Port 0: Port 13 Reference". Start the drive from its normal start/stop/speed-reference source and while it's running, check Port 0, parameter 935, "Drive Status 1". This is one of the best ways to see what the drive thinks it's doing, and you're looking to see if the drive thinks it's accelerating, at speed, at limit, etc. Sometimes a current limit that should've been set to 10 gets accidentally set to 1.0, and the drive hits this limit and can't accelerate past it. In this case, the current limit bit in parameter 935 would be true, and you'd go check what the current limit is set to. (In my opinion, parameters 935 and 936 are amazing PowerFlex 750 drives troubleshooting tools). Because you're running at a fixed speed and the drive is not hunting for its speed reference setpoint, the problem is not likely to be in the motor control options but if you haven't found it in the suggestions above, it's worth taking a look at. Start with Port 0, parameter 35, "Motor Ctrl Mode", which decides what kind of motor is wired to the drive and how it might give feedback to the drive. Volts per Hertz would be open loop control, Flux Vector would be closed loop, is it an induction or permanent magnet motor, etc. If these are not set properly to match the actual motor, speed control problems are almost a certainty. Again, not likely here for your symptoms, but worth looking at if you're not finding the problem elsewhere.  Hope this helps.

    It was done yes, but unless you're an experienced web designer I don't recommend it.
  20. FX1S-10MR with FX1N-1DA-BD mA trouble

    Yes we changed the wiring and made sure M8114 was FALSE when using voltage ouput, and M8114 was TRUE when using current output. We have a PLC in an lab environment and we're simulating difrenent values by writing them to D0 / D2 depending on output mode and measuring the output with a FLUKE.
  21. This setting is for the GOT, The GOT will disconnect the VNC client after the last operation from the VNC client. Enabling an other user to connect.  
  22. when I use Modbus TCP IP in mitsubishi FX3U then I can only use M, MW, I, IW  
  23.   I'm a bit rusty with WinCC, but you should be able to just add the data register as a tag in WinCC and associate it with a numeric value in the HMI program
  24. Hi, Is there any way to write value from D registers into M memory address? I would like to read analog value of my AI and send them to WinCC Flexible, there foud a way to use Modbus TCP IP to send data, or COM, but in both ways I can only read M, MV, I or IW address in WinCC Flexible.   I did try with MOV function to copy D register data to M, but it is not working in GX Works2
  25. Hello guys, I am new to this forum and have some problems with my PowerFlex755 EENET frequency inverter. I want to do a point to point positioning task but my problem before I can have a look at the point to point positioning is, that the inverter is always running with 5Hz as soon as I give the start command. Even if I write 0.0 to the reference the output frequency is about 5 Hz. When I change my reference speed to 10.0Hz the output frequency is 12.X (see attached screenshots). . I thought that maybe a min frequency of 5Hz was set somehow, but I couldn't find a parameter and that wouldn't explain why I have 12.X Hz as the output frequency with a setpoint of 10Hz. And an other question, have someone experience with positining tasks with a PowerFlex755 and Point to Point positioning? I think in the first step it is not working because of the problem I described above, but maybe someone have a programming example or could tell me where I can find some information about how to use the Point to Point positioning?   Thank you for advice!  Matthis Josewski
  26. Hi VeeB, Thanks a lot for the response ! It was highly helpful. Please let me know of the disconnection shall be triggered from the HMI if we want to disconnect the VNC clients...?
  27. FX1S-10MR with FX1N-1DA-BD mA trouble

    Have you examined the load resistance downstream?  Is it within the specs for the output card?  If any receiving component is not isolated, have you checked for DC offset?
  28. Last week
  29. FX1S-10MR with FX1N-1DA-BD mA trouble

    It is almost impossible that 3 cards have malfunctioning current part of analog output. I presume that you changed the wiring for current mode comparing to voltage mode, and forced M8114 to zero?.
