  4. 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.
  5. 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.  
  6. when I use Modbus TCP IP in mitsubishi FX3U then I can only use M, MW, I, IW  
  7.   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
  8. 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
  9. 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
  10. 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...?
  11. 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?

  13. 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?.  
  14. it looks like it can be set in the GT designer 3 software: GOT Setup, Advanced Setting  
  15. FX1S-10MR with FX1N-1DA-BD mA trouble

    Thanks for your reply both on this forum and plctalk! Sorry i didn't realise i got response on that forum. Today we tried the voltage output mode 0-10V instead of current output mode 4-20mA. We recieved the correct voltage in the 0-4000 range. Digital value 0 = 0volts and Digital value 4000 = 10v. However the current output mode still maxes at 6.42mA The program we tried with were the example programs given in the manual for FX1N-1DA-BD I have attached a picture of the programs. We have 3 different FX1N-1DA-BD expansion boards and the mA measurement is the same on all three.  
  16. NJ501-4300

    Hello everyone!   I’m working with the MC_SyncLinearConveyor function block in the NJ501-4300 series, and I find the manual a bit unclear. Has anyone else encountered this FB, and could you share any insights or tips on its usage?”
  17. Thanks. I'll play with that.   I also just found some of the Omron webinars on Youtube that I hadn't come across before, one of which covers networking, so I'll be reviewing that -  https://www.youtube.com/watch?v=YncUUghOeU4

  19. PLC CPU A1Scpu-S1 Remote I/O master card cards fitted Melsec I/O A1SJ51T64   Various remote I/O cards fitted for example: AJ55TB3-8D   Problem being experienced:   Parity error light flickering on master card On reading the manuals this indicates to bad signals from a remote I/O card or electrical noise problems in the data cable. No other error lights to indicate a particular remote card in question. Spurious signals to the main PLC come from various I/O cards, not any card in particular. The weird bit is if we cool the master card using compressed air the parity light extinguishes and we have no issues.   Things tried so far:   Changed the master card but same issue. Data cable from PLC to remote station (but not the daisy chains between the remote cards) If the daisy chain was at fault We’d expect to see error lights on the Mastercard at the point of daisy chain failure. Checked the voltages of data and incoming supply - both stable and correct. There are 2 mastercards in total on one rack and another on an additional rack. One card has given issues for years but now a second card is doing the same on the same rack.   Other things to possibly try:   Change all the remote I/O cards associated with one Mastercard initially but not sure if we have enough of this old gear in stock to do so. Change the daisy chains Change the main plc backboard. Manual attached. Any help or similar experienced would be greatly appreciated. manual_IB(NA)-66574 (2).pdf
  20. FX1S-10MR with FX1N-1DA-BD mA trouble

    I already wrote you reply on PLCTalk (https://www.plctalk.net/threads/problem-with-analog-output-fx1n-1da-bd.139641/). Most likely there it is not up to PLC or PLC card. It can be either bug in program or problem with sensors. Why don't you post program so we can analyze it?
  21. Hi We're having issues with an FX1N-1DA-BD Analog output module. We're using an metallic contamination sensor MCS 1000 to detect particles. This sends pulses for particles detected in a 30 second time window to a Mitsibushi PLC FX1S-10MR-ES/UL which in turn gets converted from a digital value 0-2000 pulses -> analog value 4-20mA and sends the data to our DCS. The range is adjusted so that 4mA represents 0 particles, and 20mA should represent 2000 particles. The problem is that the analog output module never sends an current over 6.42mA. It starts with 4.0mA then maxes out at 6.42mA long before the max range of 2000. We can't find a problem in the program and have also tried the example programs in the manual, but still only get a current of 6.42mA We have also tried 3 different FX1N-1-DA-BD and still get the same results. Manual FX1N-1DA-BD Hoping that someone here might have some experience with these modules Thanks!  
  22. Hi, I would like to automatically close the VNC viewer connection, which is used to view the GOT2000 HMI remotely. Very interested to know if any options are available. Thanks in advance !!!

  24. Communication between NX PLCs

    EtherNet/IP Tag sets.  Set them up on each PLC, one to transmit, two to receive.  Ideally, create structure types with the content to transfer.  (This is similar to Rockwell's producer/consumer tags, and uses the same class 1 I/O buffer technology.)
  25. So I have (1) NX102 and (2) NX1P2's on conveyor units which support an Omron AMR.  Communications between the PLCs and the robot are handled using Omron's standard ARCL function blocks. I'd like to have some communication between the PLCs - mostly checking sensors & status variables, possibly triggering minor actions. Poking around the manuals and some of the Youtube videos for communications, but looks like there's lots of options, and am looking for a simple way to pass basic info between the PLC's, all of which are on the same VLAN on our network (all have IP addresses of 172.16.209.xxx). Any suggestions on where to start?  
  26. FX5U fixed buffer Modbus TCP

    Why ??? you can do this easlly with the simple PLC comm settings. Ypu don't need any programming   OR if the FX5 is just the server just create a modbus port in the port settings and you're done
  27. FX5U fixed buffer Modbus TCP

    Hello Everyone, Does anyone know or have an example of FX5U PLC communication via Modbus TCP fixed buffer. thanks in advance  
  28. Rockwell has wisely chosen PTP (IEEE 1588) for its time synchronization.  Much more precise, and auto-configurable in LAN environments.  Put a Time Machines TM2000B on your network, set it to PTP Multicast, and turn on time synchronization in all of the Rockwell products.  (Make sure the ControlLogix processors have time sync connections to their chassis ethernet cards instead of default connections.) Every controller will quickly be within single digit microseconds of the atomic clock that drives the GPS cloud.  The TM2000B also is an NTP server, so your less modern IT devices can synchronize, too. (I have no connection to Time Machines, other than as a very happy customer.)
