  1. No GX Developer in iQ Works?

    Olly_J posted a topic in Mitsubishi

    Hi, I have a licensed version of Melsoft IQ Works. It has GX Works3, GX Works2, GT Developer (1000), GT Developer (2000), plus a whole bunch of other software packages that I have never used but it does NOT have GX Developer. The site I work at has a couple of old A-Series PLCs that I cannot open with GX Works2 or GX Works 3. These files have been successfully opened in GX Developer on another computer, but I do not have it on my computer.  Does any know, does IQ Works not come with GX Developer? How do I get GX Developer? Does it have to be purchased separately?   Any help is much appreciated. Kind regards, Olly  
  2. Hello, I have a Q02CPU and QJ71E71-100 terminal and want to do a simple test of the Fernhill SCADA system. I have successfully connected the Fernhill software project to my PLC and gotten a word variable from the PLC be represented by a tag in the Fernhill SCADA system. However, I have issues doing the same for my bit variables. In Fernhill they should be internal relays but I get error 4031h in Fernhill: Melsec Error 4031h - The specified device number is outside the device range. I do not understand what is wrong. My PLC variables are each a global variable, internal relay in other words. In Fernhill I define each tag as an internal relay. The "device" from my simplified understanding is the identity of the variable in the PLC. It matches the PLC and Fernhill as shown in the pictures provided. Thanks in advance! PS. I don't get the error if I define the tags as Data Registers instead like I did for the analog variable. But 1) That is not what they are and 2) The tags don't change when the PLC variable is modified. Just a bit suspicious that it stops complaining when it is clearly incorrect...
  3. Hi,  I write a CAM function to sync 2 axis (Rotary & linear). i am using a virtual servo as master, and 2 physical servos as slave. The problem i facing is, with the exact same CAM profile setting, when difference speed used will give difference result of movement. Below is my setting, Master axis     linear motor move 0-180degree   0-500mm 180-360          500-0   when running with slow speed, it move following the CAM profile setting, however, when moving in fast speed, the linear motor will only move halfway then start to moving back 0 already. Has anyone encounter this issue before? is it i missed out some setting? Thanks.

  4. QJ71C24N-R4 Modbus communication

    madhan posted a topic in Mitsubishi

    Hi all, I would like to know how to communicate scale indicator device mettler Toledo ind 320 using  module QJ71C24N-R4 by predefined protocal   I also tired to communicate in CH1 with the G.INPUT instruction to communicate when the device in MT continue mode it does communicate but I dont know how to convert value Now by trying modbus communication predefined protocal works fine but i cannot read data the is no SD/RD transmission happening  Can anyone help me with this  Thank you serial monitor.gxw serial monitor.gxw
  5. Hi All, I need access to a the Safety function blocks within a safety CPU using sysmac studio on a machine we are upgrading.. Is there a generic password available to gain access? Best Regards, Paul  
  6. Hello, In GX Works2, what do asterisks before function block input and output variable names mean? Thanks,    
  7. Hello, I am trying to create a project in GX Works 3 with a R02 CPU, but in the "New" Tab "Change Module" Tab this CPU doesn't show. However, if i gow to Module Configuration i can select and drag the R02 CPU, but i can't define it as the CPU of the system. Another problem i have is that i need to migrate a A1SH CPU project to an R02 CPU project. From my understanding the software tool for A1SH is GX Developer and for R02 CPU is GX Works 3. Is there a way to convert the project or i need to do a new one and adapt it? Thank you.  
  8. Hi all  I need to view a project in instruction list format on Mitsubishi GX Works 2. On GX developer the shortcut is Alt + F1 or View tab then press instruction list.   Thanks

  15. GX Works3 Projectlib Locked

    Lolopas posted a topic in Mitsubishi

    Hello, I have a problem that I need to solve in a PLC program has it's projectlib locked.  I work for a company that contracted a PLC programmer before my time to program their new version of their control cabinets. The company did not write any specific contract with the contractor and just relied on his work. The guy later delevered a buggy software that is kind of functional (the bugs came up at the commissioning after the guy was paid and now he refuses to help or to provide more consultations). I have as a task to freshen this up and make it work without bugs, the problem is that the Projectlib is locked and I cannot access the source code.  The only thing that I can changes that I can make to the code is to put some logical circuits between the I/O of the already existing function blocks, which solved some problems, but not all and it keeps one of the most important ones as well. Anyways, that's my story, so now my question is, is there and possible way of unlocking the projectlib? Any feedback would be highly appreciated. Thanks in advace!
  16. Hello. I start learn GXW3  and i have problem with simulation. I trying to connect GT Simulator with GX simulator 3, but it's doesn't work. GT Simulator 3 easy connecting with GX Simulator and GX Simulator 2 and it's working. So i can't say that problem in GT Simulator 3, but GX Simulator 3 works too, when i starting it. All software configurated without any errors (IQW,GTW3,GXW3). I using GX Works3 1.026C, GT Designer3 1.151H, IQ works (melsoft navigator) 2.12N.   All time when trying to connect, popups this msg. Settings of GTS3 Note from HELP. Does someone know how fix this problem?

  18. unit of time in D8284

    arcp posted a topic in Mitsubishi

    Hello PLCmaniaccccssss, What is the unit of time in 'average time for the channel -1' (D8284) while programming for analog inputs? I have moved k10 to D8284 in my program in gxworks 2, does that mean the time average will be taken for 1Sec or 10msec or any other time unit??? I require this to eliminate the flickering of the input from the load cell transmitter. Thanks and God bless!!!
  19. Hi, I have quite a noobie question. I want to create a function block to do some simple operations on 2 variables. Both variables are In/Outs (see picture attached). How can I make this function accept variables regardless of the data type? Given these is just simple math I am able to use the same instructions in REAL, INT, UINT, etc. But, the function block only lets me assign one Data Type to the In/Out variables.

  20. GX Works 3 (R04CPU) Device Memory

    ButtonBasherNo445533 posted a topic in Mitsubishi

    Hello,  GX Works 3 / R04CPU. I'm using the Device Memory so that I can link the HMI to my PLC. I've set aside some memory, in this case D3260, to be used as a Real (32 bits data, Float single precision) to be set by the HMI (operator adjustable setting) and read from the PLC. I thought I'd move D3260 into a local label for readability/testing purposes, and it says I cannot move an Int into a Real - which is fair enough, but, how/where do I set D3260 as a real? Do I use some Functions to take D3260 + D3261 and make it to a real, or define the data area as a real somewhere...   Dumb question I know, I'm new to GX Works 3. Thanks very muchly

  23. Unconverted Ladder Code?

    berkotropia posted a topic in Mitsubishi

    Hi All, Please see attached screenshot: Whenever I want to save the ladder program or start simulation, this window pops-up. If I press 'yes' I loose the whole work. I tried to open existing program and modify it, but it did the same. When I clicked 'yes' I lost all modification and just the original program remained. (I made the program in the morning, opened and saved many times but it started popping this window later.) I work with FXCPU series, FX3U/FX3UC type, simple project in ladder. This worked well but now is not anymore. I use Melsoft GX Simulator! Can anyone advise why this is happening? It is very annoying! It is pointless to work on anything now! Many thanks
  24. hello Every one,    I am using a CP1-L PLC and want to communicate to domino ax350i printer over TCP/IP socket programming. For socket programming, I used Omron Function Block CPU012_SendCommand.  I defined network ID and node address. However, I am getting 0502 error which means routing table is not set yes. So, how can I set routing table for both devices?. my PLC on 192.168.250.1 and Printer is on 192.168.250.123 node 7000.    Can any one suggest me best way to do.  Thank you   attached file is for what I did in setting and program for the communication.
