  1. PLC Reset?

    Yes, you would want to add a start/end address that would be retained always. If memory space allows, i would just set this to the entire range of D. If not I typically would use 10,000 - end, that way I know the data location is up out of range with the rest of my address mapping. I believe the HMI can have it's own memory, but I don't utilize that so i am not 100% sure.  
  2. PLC Reset?

    Project navigation  PARAMETER > PLC Parameter.  Then select the device tab. Any data points listed under Latch 2 Start - End will remain through power outages / reset.
  3. YASKAWA v1000 plc

    I would check the physical motor install, verify bearings are good, check runout / alignment, things like that would cause the drive to be working too hard. Also recommend plugging into the drive and using the software to monitor the drives performance. it might point you in the right direction.
  4. Rural public water system in TROUBLE

      With that low number of I/O  I would bet its mostly an order of operations & timer based system. It might be a good idea to try to create a map of the functions you KNOW it does and build from there.  A scope or meter on the outputs to get a timing and order. if there is a HMI look for any settings / parameters.
  5. Data register lost when the power is off

    Glad to help.
  6. Data register lost when the power is off

    PLC Parameters > Device Tab. Set a start / end address for the Latch 1 / 2 as needed.  Latch 1 is data retained during power cycles but reset with Latch clear command. Latch 2 retains data always.
  7. PLC to PLC

    I created this program to help me remember how to set this up. EthernetLink.gxw
  8. Unconverted Ladder Code?

    Your screenshot shows un-compiled code (as well as an incomplete rung).  First complete the rung by tying Y0 contact to where it needs to go, probably a vertical line before /X1. Then compile your code <Compile Menu> <Build> (F4 - Shortcut), if you are online with a Running PLC than Shift+F4 for an online build.   Then save your file.

  10. GX Works 3

    you could try to uninstall with Revo Uninstaller. It includes extra steps after uninstall that scan registry and left over files for a true clean slate.

  12. GT designer

    I believe if the programs are linked to a navigator file, you should first open navigator, and then open the HMI from there. It might be upset if you open the HMI file directly because navigator has the files linked.

    EthernetLink.gxw This program was my base for setting up a similar communication link.
  15. Internal relay M

    Little more detail in case you are new to the Mits PLCs M are basic internal relay bits.  D are basic internal Words L are Latched internal relays (their state remains through power cycles) X/Y Obviously inputs & outputs T are timers C are counters Z are pointer modifiers i.e. [MOV K150 D100Z1] would move value of 150 to D100+(Value of Z1), so if Z1 = 10, D110 would 
  16. Got 2000 button over button

    Could you instead make 1 button, but change the function in the PLC depending on the condition? You can even make the Text change based on the condition too. 
  17. CC-Link Network Dropping Out Ideas?

    I had a similar symptom 2 years ago. We had a terminating resistor installed across DA-DG instead of the correct DA-DB.  Just one more option to check.

  20. Im checking in my my software guy. 
  21. Have you used these Balluff modules before?  I have one that I was testing on, but hit a road block when the CC-link card must be some version or newer in order to run data read/write commands. 
  22. I spoke with my programmer, here is the manual that he used to write our software.  Basically he uses GetDevice to read data less than 2 words, and ReadDeviceBlock to read greater than 2 words.   MX Component Programming Manual

  25. I personally can't give you the guidance on how to connect, but I do know that our software programmer does exactly what you are asking with their code. I do know that you need MX Component installed on the PC, to establish the connection, it can't be done directly through the C# so that might be your missing link.
