  1. 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 
  2. 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. 
  3. 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. 
  4. Counting chain links on a conveyor

    ---| Running Reverse | --- [ = Count K1 ] ---------------- [ MOV K3785 Count ]
  5. plcModule.ActLogicalStationNumber = {StationNumer you set in MX Component};     int result = plcModule.open(); //Open the comm port    
  6. Im checking in my my software guy. 
  7. 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. 
  8. 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

  11. 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. 
  12. Input on the left vertical line

    | X0 | ----- [MC n1 M0] Stuff to run when X0 is on.. ---------------[MCR n1] Stuff that runs all the time
  13. This button performs the 8 actions when pushed.  Has anyone ever had an issue where some actions were not triggered?  This system has been running for years, but Tuesday we had an issue where only the first 2 actions happened, but the remaining ones did not.
  14. The Bits that are SET by this button are reset by the PLC on a up-pulse only.  These functioned correctly at the time of the issue.  All the momentary bits shown are only on the HMI, and none controlled by the PLC at all.  These were supposed to break latched sequences such as this one shown here.  This is what did not work as expected.  But they have worked every other time before, and since without issue.   
  15. Its a GOT2000 and Q03UDE PLC I'm not sure what you mean about permissive logic.. But like I said, this system has been running & working for years.   Is it possible that the PLC scan 'missed' those momentary triggers? 
  16. CCLink

    I made this excel sheet to help me remember, let me know if it helps you too.  CC Link Station Address.xlsx
  17. INCREASE AND DECREASE VALUE D200

    Most VFD have a multiple input speed selection settings. Maybe that would be easier?  Or can you just use analog signal and a POT or HMI to set the output?   
  18. Anyone used an RFID reader on company badges?

    We are Mits standardized here. Normally Q06UDV.  I have done several Barcode readers over ethernet, and am very familiar with that setup and use.  My question was more aimed at your second point about the challenge of using the data. I was hoping for some examples of how others have done that.  The MES system you mentioned, were you able to tie directly with the central ID system or did you have to create a separate copy of the database? 
  19. As part of a request to control some processes, and discussing the shortcomings of unique passwords, or keys, they asked if the company badges could be used instead.  I would imagine such systems exist, but does anyone have experience with them?
  20. EthernetLink.gxw   I have posted this example in the past. It is not using SOCSEND/RECV  but using the GP.READ i was able to get reliable communication between 2 PLCs. Only requires the one PLC to be modified, and you pick what addresses you want to read/write to on the other PLC. 
  21. Q to Q Enet Comm - GP.Read Instruction Error

    Gambit is correct.  In my example that you used, I was reading from Network 3 (D2004), Station 1 (D2005)  with Your PLC Settings, you should be reading from Network 1, station 2   Also in my example, under OPEN SETTINGS, I was setup as [ TCP, Unpassive, Receive, No Procedure, Disable, No Confirm, 20512 ]  You have Send and Confirm.   I dont remember exactly what those settings meant but I know I have it working..    Direct Ethernet connection is fine BTW. No switch or crossover is required. 
  22. JP.Read QJ71E71-100 Channels

    I would probably setup the various connections in different D addresses, then use a timer/step logic to connect to each one by one. I think you'll be surprised how fast it still is pulling the data. 
  23. VPN Advice

    I have not used personally, but I have tested the system from Ewon VPN Systems.  They even have a Mits demo online to play with
  24. Minimizing OR function

    The above will work, but just to give you more options.. I have been a fan of the NOT-NOT style rungs for large groups of OR.   |/A|---|/B|---|/C|---|/D|---|/E|---|/F|---|/G|---|/H|---/----(OUT)
  25. ethernet comms between different networks?

    you do have the subnet set to 255.255.0.0 in all PLCs right?  You mention a test leaving it blank, but i think that would actually default it to 255.255.255.0
