  1. CCLINK program problem

    Hello everyone, I want to ask,, Does address mapping use this concept to do "remote i / o station" can be done? following the network parameter settings for CCLink and I tried to program with this ladder, is that correct?  
  2. Mitsubishi FX2N, Servo Output problem

    Hello guys, I am facing a problem that our Servo is generating output for only reverse direction, when we give forward command from HMI the output Y0 is active but when we give reverse command same outut Y0 is high, other output which is Y4 is not high, what could be te possible reasion.

  4. Hi all. I have a Kinetix 350 and an AB TLY servo motor. I'm using the drive's STO function. AC power is supplied into the drive, passing through an "M1" contactor. It makes sense to m e to keep that contactor open, preventing AC power to the drive, until the drive is fully awake.  Is that what you guys do? Someone suggested to me in another forum ( http://www.plctalk.net/qanda/showthread.php?t=121021&highlight=drive+awake ) that there is no reason not to supply power to the drive right away because the STO function is inhibiting power to the motor anyway. 
  5. Hi all,               I am working with FX-3G PLC and it is communicating with a Weintek HMI. I am feeding a data in HMI in float format through a D register. But it is showing some other value in PLC. I don't know what is needed to done to extract the same float value into FX3G plc. So the basic question is how to store that float value in any of the registers in FX-3G plc? Requesting your support please.
  6. Vijeo Citect - write to tag - error

    Hi everyone.  In Vijeo Citect SCADA I created some tags and I try to write to a bit device of MELSEQ Q PLC. But I get this error : Cicode General software error. Note: I can read from PLC.

  8. Mitsubishi PID controller design help

    Dear all, I need help in design of PID controller in Mitsubishi PLC fx3u, I what should be parameters for initial, and how to start and stop auto tuning.
  9. Hi All, I have an AB servo TLY-A110T and 2097-V31PR0-LM Kinetix 350 drive. I thought that it was fully configured and ready for tuning, but when I issue a MSO it immediately starts to spin the shaft (no load yet). This lasts about a second until a Physical Axis Fault, Excessive Velocity Error occurs. I've double and triple checked the feedback and power wiring, and everything looks right. Is there anything else I can check? What can I do to trouble shoot this if I can't even give an MSO? Any insight is greatly appreciated.
  10. So I need to find a way for a Mitsubishi PLC to communicate with a PC - ideally sending a binary number through ethernet to a PC program that reads it and tells the PC which files to open. I think I can create the PC program with C++ or Visual Basic without too much struggle. But I am unsure of how to get that binary ID from the PLC and into the PC program. I have done a little bit of research on MX Component and MX Sheet, and also MC Protocol but all seem a bit outdated and/or just over my head and I need some better explanation - I'm pretty new to PLC and programming. I feel like it shouldn't be terribly difficult to get 1 external binary number into a PC program. I'm sure someone has done essentially the same transfer and I just want some ideas. -What kind of connection support do I need to transfer data (Likely just a D-bit) from a PLC to PC? -How would that/those bit(s) be accessed in Visual Basic or C++? I'm assuming some type of library function that will call the value
  11. Hello All I am new to sysmac studio, i am using a NJ301-1200  and R88M-KN10H servo drive , i connected the servo to the NJ using ethercat. I was able to write a program where i was able to activate the servo from the NJ using the mc_Power instruction . My question is , i am not able to run the servo using the mc_movevelocity and mc_moverelative . Do any one have any suggestion to how to go from here ..  
  12. Bonjour, Hello, I use a l33erm automaton and a Kinetix servo motor . This servo motor drives an engine with a chain moving in steps of 100 millimetres (there are 15 steps on the chain ) At each top of a cell this motor advances by 100 millimetre. in reality it advances from about 0 to about 100. Sometimes it is 100,002 times to 99,997 (this is important further) and when I give it a top it goes back to about 100 (100,003 times to 99,996) And so on and so forth up to no problem, I use a MAM with an absolute type of movement. It works.     However, this does not work any more after a rearmament following an emergency shutdown. if it is a 100,002 no problem at the next top the chain advances one step But when the engine is shut down at 99,997 and I give it the order to go to 100 it advances only by 0,003.  This only happens after an emergency stop (or door opening). Thank you for the help you can give me excuse my English this is a machine translation Un séjour sans faille
  13. Hi, I am developing Servomotor Drive Module for Mistubishi servomotor to control its positioning and speed. I have combined two FBs of the RD77MS4 FBs 1. SetPositiiningData FB 2. StartPositioning FB  and defined in Local label as  Label Name: i_stModule , Data Type : M+RD77 Class: VAR_INPUT. I get Error Invalid device or invalid constant is used. Can someone tell me how to define Module Label while combining two  FBs using same Module. Please

  15. Hi all,  At my work, we are unfortunately still using GX IEC Developer 7.04. All of a sudden I can no longer open any project at all with my GX IEC Developer. I can start the program just fine, but as soon as I choose a project to open I get "cannot initialize communication manager". And after this, I get another 2 "cannot restore parameter file. param.tmp not found" and "cannot restore transfer setup file! cnct.tmp not found!". Doesn't matter which project. And I have opened these earlier with no problem for years. I have tried reinstalling ALL Mitsubishi software on my PC. And restarting PC. I can't find a link to any other changes I have done on my PC either... Does anyone have any idea how to solve this? Best
  16. A1S68DAV parameter

    please can anyone tell me how to set A1S68DAV analog output module parameters , such as voltage output and resolution? or is the parameter can't be set at aLL (ie, fixed at -10V to 10V)?
  17. Barcode Reader -- GOT

    Dear all, I've already connected Barcode reader to input data for GOT, But, before using Barcode reader to scan data for GOT, I need press to position where will receive data. Example: if I want to scan data for Barcode#1 --> I need press to GD2000 --> Scan Barcode#1 Next, Press to GD2005 --> Scan Barcode#2 .... It's waste time press in HMI.  So, I would like do as flow: Press to GD2000 -->  Scan Barcode#1 --> (data auto fill to GD2000) --> Scan Barcode#2 --> Data auto fill to GD2005 --> .... Who have experience about this, could you share method for me? Thanks and Best regards!   BARCODE.GTW
  18. Salvage PLC to play with, but...

    I was at a salvage yard not long ago, and I saw 16 robotic arms, 4 turn tables, and a truck load of PLC cabinets being scrapped.  I asked if I could buy one of the cabinets, and the answer was no, but they let me take what was inside of a small cabinet (they only wanted the metal).  I got my hands on a q series - complete with a base unit, power supply, CPU, and a few i/o's.  Here is where I need a little help. I want to play around with this setup, but there is no way I am buying the software for it.  Is it possible to use an open source PLC software to program and run this PLC?  I want to use it on an aquarium (of all things). Any advice is welcomed.

  22. Mitsubishi & Omron -OPC-UA - KEPWARE Server

    Hi,In a project I have four Progressive Pressing Machine. Each machine with different PLC like Mitsubishi 'Q00UCPU' with 'QJ71C24N-R4', 'FX-3U-16M', 'FX2N-128MR' and Omron 'CJ2M-CPU13' with 'SCU41-V1' module.Now my task is to connect all PLC with KEPWARE Server through OPC-UA.Note: There is no Ethernet Port available and existing RS232 port are all connected to all respective HMI'sIn this scenario, I would like to know, do all the PLC that i have mentioned above supports OPC-UA through Ethernet if i add a new Ethernet module to each PLC. So the data transmission will be faster or else should I buy RS232 serial communication module to communicate through OPC-UA.And also i would like to know, what kind of "Industrial Switch" will be perfect for this application.Kindly suggest a best way to prove myself.Thanks in advance
