  1. Communication timeout Error - GOT2000

    Did you able to read the GOT or do communication test?
  2. Control Melsec-FX-5U over internet in realtime

    Basically, you want a remote access to your PLC through internet? Try go search for MCWorks and MXConfigurator.  
  3. MOV H400 K4M60? Hexadecimal

    Hi guys, I come across a program with instruction MOV H10 K4M60 But I cannot understand how this will turn on M64? Tried to convert from H10 to binary (00010000). Also there is MOV H400 K4M60 and I'm not sure which bit is trigger. I believe it was M65 but the binary is 010000000000. Thanks!  
  4. MOV H400 K4M60? Hexadecimal

    Thanks! How about H400?  Binary is  010000000000 , does it mean it was for M70?
  5. I believe you need to check all PLC/HMI, see if any of them if connected/referring to network #3. If I'm not mistaken, you could check at CC Link configuration, maybe for IO mapping. Btw, which model of PLC?
  6. Error **03 Special Parameter Error

    Looks like something disconnect from the module. Is your ENET module blinking? Try to ping the PLC.
  7. GXWorks2 - K8M300?

    Hi, I found this instruction on this ladder and wondering how it is calculated? From the right, I understand they compare value from M0-M31 to M300-M331 because they started next with M32/M332. I thought it K8 * 8bit = 64 but it is not.      Thanks!
  8. GXWorks2 - K8M300?

    Thank you very much.
  9. I have had an issue with FX5U before. The PLC wont power on. I was told by our contractor, the PSU can be repair (change electronic part). But luckily, the PLC power back on after we dismantle all the part and do air spray cleaning. 
  10. GXWorks2 - K8M300?

    Thanks for your reply. Why x 4? Any reason? Applied to D, X and Y as well?
  11. How to check for spare point from PLC program?

    Thanks a lot!  
  12. Hi, I was wondering, is there a better way to check for spare points beside searching for one-by-one in the program? Thanks!
  13. GX Works2 installation problem

    Thansk! 2nd method works for me.
  14. GX Works 3

    I encounter this issue. Any solution yet? 
  15. Q02CPU Error 2200

    It is not. During PLC read, you need to select either to read from Program Memory/SD/RAM/ROM. Same during PLC write.
  16. Q02CPU Error 2200

    What model of new CPU? Same model? If Im not mistaken, from Write option for GXWorks, you can select the location to write the parameter.
  17. GOT setting to connect to PLC through GOT

    Try check this setting. From GXWorks Parameter > PLC Parameter From GTDesigner Common > Controller Setting
  18. Keypad not showing in simulation

    Found the solution for this. Check for trigger device.in numerical input setting. Make sure the device is ON and you good to go. Normally this was setup due to make sure only one HMI can operate the SP. There are 2 HMI for this system located at different places.
  19. Hi guys. Somehow I cannot open keypad for numerical input from simulation. The HMI is using user-defined keywindow for keypad. Setting as below: Any advice on what to check? I have been messing around with the setting with no luck. Thanks!
  20. Hi guys, So I want to divide two D value and comparing the result to setpoint and trigger alarm accordingly. Most the time, the result of the division will come out with decimal point. I am not familiar how to deal with decimal, floating, integer, etc before this.  I try to do as below, actual result is 1.666.  D8100 - 1 , D81001 - 6 How do I properly put decimal value in D and to show in HMI? Thanks!
  21. Q-Series - Decimal value in HMI?

    Thank you! WIll keep this in mind in future.  Btw, integer in PLC cannot read decimal right? They required two D register, how do I compared them in PLC with single integer from HMI. Eg, from calculation, result is 1.35. Register at D1 = 1 and D2 = 35. How do I compare with SP from D3 = 1.35?
  22. Q-Series - Decimal value in HMI?

    Thank you very much!
  23. Q-Series - Operation Error 4100

    I believe there is no SD card attached. Any advise on what should I check? Some background, 1. There are around  7 PLC connected together through MelsecNET. 2. All PLC indicate this error. ERR LED lit up but not affecting sequence. 3. LED ERR will turn off after reset and come back on later, maybe after the instruction trigger.  
  24. Q-Series - Operation Error 4100

    Hi guys. I found error on PLC and from PLC diagnostic I found this Operation Error 4100 as per attach picture. FYI, there is no SD card mount onto this PLC. I wonder what is ATA card. This error wont affect the operation. Any advise on what to check?   This ladder is pop up when I clicked, error jump.   Thanks.
  25. Q-Series - Operation Error 4100

    Hi Gambit, Thanks for you reply. What do you mean by File read/write? Is it the same as normal read/write like "MOV D1 D2" or is it read/write to/from ATA card? Sorry I am not familiar with this instruction.  Btw, why there is error when read/write command is used? Thanks.
