  1. GX Developer Special Relays

    HELLO TO EVERONE!!Could someone please help me find a special relay command (not a real relay) that stays activated when it receives a pulse from a NO contact (X0), and desactivies when it receives a second pulse from the same NO contact (X0)? So en conclusion I need to control a relay with only button.I hope you understand me... Help please....

  4. FX3u PLC MITSUBISHI CONNECTION PROBLEM

    Hello everybody. My FX3u PLC doesn't turn ON, I connect to 24Vdc and nothing, not even the POWER led :( Any recommendation??????????? PLEASE   
  5. Hi everyone! I just need some help regarding on a project I'm working on. The idea of my setup is I have an Omron NS8 HMI connected to Mitsubishi inverter (FR-D700) through Modbus RTU Protocol without any PLC (is this possible?). The master is HMI and the slave is inverter. I use this so that I'll just input a running frequency to the HMI and the HMI will write it to the frequency. I have completed the setup, wiring and parameter setting on the inverter. Here is the problem, when I created a screen and transfer it to HMI and run some test, there is no reaction on the inverter and I just can't even make it run. On the screen, I created a Button for run signal with address "INVERTER:400009.02". Is there something wrong with my address or setting that I miss perhaps. Any help or tips regarding this. Thank you in advance.
  6. I have two plc, they are the same but I need to see and transfer the programming of one to the other. How can I do this ? I need a software?  What's? What's I need to do this ? Thanks. 
  7. Hello, there, I need some help  (a lot, maybe). I'm a rookie using PLC. In the company I work for, we need to receive information from the machines (plc controlled) remotely. We are using FX series (Fx1N, fx1S and fx2N in one plant and f33g and fx3s in the other) and I need to know how I can connect this devices (which Ethernet connector do I need, which software). If you can help me with the names I can do some research. Ah, you need to know that I'm in a 3rd world country (no easy acces to regional providers, well I can contact them via email). Sorry for my english, sometimes is a little rude but is my second language. Kind regards,   Ing. Eduardo M.
  8. Hi , I need help in assigning Link refresh setting between PLCS ,B and W address exchange between QCPU s and  two DOPL module  connected in ring network configuration. We  have used qj71lp21-25 in 5 cpu station.    
  9. Hello EveryOne, This is my first time in this forum. I am facing issue with DOPSoft on my laptop. When i am trying to execute offline simution of the screen, I get an error saying "TickersEmulator stopped working" & it closes the simulation screen. I assume its an error related to display/Screen etc. But not confirm to rectify the issue. It working fine on other PC. Where can i work to resolve the issue ???

  13. Alpha2 Help?

    Hi Although I have used programming languages like basic and C for many years, I have recently tried to get to grips with programming (with the software (not direct)) the Alpha2 I have to admit that I am struggling! I have made a little progress since I worked out that you have to build almost everything at a very low level. But I still can not work out how you make variables that can be used in the program? For example : If condition A is true X = 10; But if condition A is false then X = 2. I have tried using the bit inputs on the math FBs to enable/disable values of X, but although this will initially alter the value , sending a 0 bit merely freezes the calculation and the value does not change. It seems like it should be such a simple thing to do? Is there a fundamental concept I am missing? Any help would be greatly appreciated
  14. Hello everyone, I am controlling a mitsubishi servo amplifier type MR-J4-20A-RJ with a Mitsubishi FX5U PLC. I am using DDRVI instruction to output the pulses to the amp with pulse/sign connection. Servo seems to work as requested, and cumulative pulses in MR configurator make sense. The problem: I can follow the output pulses and get a "position" from special register SD5502. If i understand it correct, the register sums the pulses output. If drive the servo to other direction, the register keeps adding up the value, not subtracting it. As i am new to mitsubishi, what would be the right way to get the position data? Is it possible to use the special registers for it, or should i just connect the servo to output the cumulative encoder pulses to PLC?   Thank you all for your time!
  15. Hi, I am not an advance user of PLC's but I can muddle my way around. I am currently reviewing a program written by another person and I will need to make some modifications. I have noted that on a M8002 pulse the Mitsubishi FX2N-8AD CH5 to CH8 -[To K0 K1 H3333 K1]-  are all set for a 4-20mA current input which is perfectly acceptable however on the same pulse is written -[TO K0 K22 K0 K1]-. I was hoping that someone could explain exactly what this is doing. I understand that the first K0 is the module number K22 is BFM#22 but I am not sure exactly what this is and I am a little confused by what is written in the manual. (8.2.7 BFM #22: Sets convenient functions: The functions described below are assigned to b0 to b3 of BFM #22. When a bit is set to ON, the assigned function becomes valid. When a bit is set to OFF, the assigned function becomes invalid..............) .Due to not knowing exactly what BFM #22 is doing I am unsure why the next K0 is used and the final K1 is to do this operation once? I apologise if this seems like a very basic question but I just can't seem to find any further detail online regarding BFM#22 that I can understand. Any help would be greatly appreciated. Thanks for your help. Paul.
  16. I an seeking guidance on how to link two mitsubishi PLC over Ethernet and have them pass bits/words between them.  PLC 1, Q03UDV built in port  ---- GXWorks 2 v1.54N   192.168.1.39  (QJ71 in slot 1 is also available if req'd) PLC2, Q02H with a QJ71 Ethernet card in slot 2.  Same GXworks2   192.168.1.35   I know with a modbus or CCLink setup, there is a place to declare the buffer > X/Y parameters, but i have found no such parameters for the ethernet connections. I found 1 document describing the JP.Send instructions but I have not been able to get that to work from the example.    any help would be greatly appreciated.     
  17. Mitsubishi Diagnostic

    Hello everyone. If anyone knows how an empty slot on base  is defined by "system monitor" service of GX Works which shown in attached picture? I think this information is read from any CPU register address(Maybe SD or SM and  etc. registers). But I don't know exactly which address is deploying an information about empty slot on base. Thanks.
  18. Error on Mitsubishi Servo Pak

    I have a Mitsubishi servo Pak #MR-J3-40B with an error 25 and 95 flashing. Could not find any help on the web or in the manual. Any help appreciated.
  19. Dear Forum, I am working at a Gas Processing Plant which is running Emerson Delta Distributed Control System (DCS). The Control System is communicating with over 24 3rd party Packages in the field over Modbus TCP/IP using its VIM Module. We have implemented redundant communication with most of the packages so we have a primary switch and a secondary switch. We are facing a communication issue regarding an Over Head Compressor (using Rockwell Allen Bradley PLC) and Instrument Air Compressor by CAPS Australia running XE Controller (Dedicated Controller). The issue is that when the Over Head Compressor is plugged into the VIM Network (Network in which all 24 3rd Party Packages are plugged), the Instrument Air Compressor **stops communicating**. We can't even ping the compressor. At times the Instrument Air Compressor does reply but with TTL of over 30ms. When OVHD Compressor is plugged out, Instrument Air Compressor resumes communication. I have attached wire shark capture of the network with and without over head compressor. When the OVHD Compressor is plugged in, the capture shows heavy traffic being generated by its PLC (IP address 192.168.1.60). Another physical observation is that before the OVHD Compressor is plugged in the VIM Network, the NTRON Switch (Ethernet Switch) in OVHD Compressor panel shows static lights, unlike lights of a normal healthy network. When the OVHD Compressor is plugged into the VIM Network, all the lights of switches in VIM Network which were blinking previously also become static. Do the static lights mean that the network is being choked due to heavy traffic? Below are links for the Capture, IP Scheme and Architecture of Over Head Compressor. https://www.dropbox.com/sh/ar7ss8zzoo96g37/AAADguRpUDtdOnmN3xQX-Wlpa?dl=0 Please also note that OVHD Compressor is using following IPs 192.168.1.59  PLC (Internal PLC IP) 192.168.1.60  PLC (Internal PLC IP) 192.168.1.61  HMI (Internal PLC IP) 192.168.1.62  RedLion device for DCS Communication I would really appreciate if anyone would help me trouble shoot this issue.

  22. promblem plc

    Hi , I started my plc about 5 years ago for plastic unit but now  When I turn them on, the correct screens appear on the HMI terminal, but no data is coming through from the PLC. After a few seconds, a pop-up appears sayingPLC No Response 00-00-0". Does anyone know the meaning of this message.Then I am on and off several times so that the device is turned on and working properly. I DON'T KNOW ?
  23. Hi guys, I'm having a problem on how to save the home position for omron servo driver. How does the servo driver know where the home position is after turning on? Btw, I am using Mitsubishi FX3u for my PLC
  24. I need to learn about position control for 2 axis with a QD75MH2 module. I know how the basics about programming with the Q Series PLC but I've never done any positioning control. I'm having a really hard time understanding the program I have to modify and I don't know where to start. Is there any course you might recommend? Even if I have to pay for it. Thanks.
  25. Hey guys, first post!  Friends at Practical Machinist sent me over here b/c we were stumped.   I have a Mitsubishi 500M control CNC machine.  There is a section of the ladders that i don't understand, and Mitsubishi couldn't help, and the OEM is defunct.  I do not have a hardcopy of the ladder circuits. I have an output , [Y13], that i can't get to turn on because of an internal relay | M453 |       see pic 1 When i searched for relay M453, it seems as if it's in some sort of array function.  see pic 2 None of the relays from M448 thru M512 ever turn on.  I understand that all these are controlled thru this circuit, but i have no clue what is going on with the R registers, and how the heck these internal relays can be turned on. Can you guys help explain?   Thanks!
