  1. Hi All, Have recently embarked on a project that has required me to change over to GX Works 3 in order to link an IQ-R120PCPU to a Citect 2018 SCADA package . In days gone by under IEC Developer and GX Works 2 it was quite easy to establish communications between the programming package running in simulation mode and a running Citect system using the MXCOMP driver via MX Components to perform offline testing. Can't seem to find a way to get it to work under GX Works 3 though, has anyone tried a similar setup Simulated logic in GX Works 3 is running fine and can modify the IO from inside MX Components "PLC Monitor Utility" program so there is no issues there, just cant get Citect to communicate. MX Component comm's has also been proven reading/writing variable to an excel sheet with GX Works 3 in simulation mode also. Attached are the files for getting GX Works 2 up and communicating to Citect 2018 via the same method i am trying to get working in GX Works 3 in case anyone ever needs to use that method. Any help would be appreciated.     GXWORKS 2 & CITECT
  2. Hi Guys   I am trying to change a profibus module on a Q02CPU from a QJ71PB92D to a QJ71PB92V, but when I try to download I keep getting the error Flash ROM writing could not execute rightly.   Now I can download and upload code thus I think the Cable and PLC power OFF is a null. How would I do this? I am using GX Works 2, as I do not have GX Configurator AD.   Kind Regards Morne
  3. GX Works3 problem

      Hi Guys, Can you help me out with this question The servo motor connected to axis-1 rotates in the forward direction when the M1 button is pressed, and in the reverse direction when the M2 button is pressed. When two buttons are pressed at the same time, the engine stops after 5 seconds. Write the program that performs this process with GX Works3.

    Hi all, I'm trying to set up the analog on channel 1 of the fx5-4ad module. I've set my parameters but I'm wondering if anyone has an example of the ladder side in GX works 3. I'm looking to read the signal in an hmi. Thanks 
  5. GX Works 3 Recipe

    Hi all I'm trying to incorporate a recipe system into my plc program. I've been through the sample which I s great help but my question is this. How many devices can be controlled using a recipe? from the looks of it I can only control 3 devices but I'm looking to control about 6. Thanks in advance for any information folks.
  6. Original FX3U project written with GX Developer FX Version 8.45X. I now want to program an FX5U with the same program (well, slightly modified). I have MELSOFT GX Works3. How do I import / convert the original project? I have done a web search but can't find the answer. The installed help files don't seem to cover the topic either. Many thanks.

  8. MR-J4-60GF-RJ Programming

    I am new to Mitsubishi (only done Allen Bradley) and Im tasked with programming a MR-J4-60GF-RJ servo drive with a HG-SR motor. I am using GX Works 3 and have a R02CPU and I am wanting to use CC Link IE Field Basic communication with this. Do I have to use the point table to move this motor from "Point A-B" or can I send absolute positions, speed, etc to a given position. Any advice/programming examples would be great. 
  9. GX Works 3 - PID control

    Hi, I am using PID function (PID operation instruction) from GX Works 3 library but it doesn't work. I set all necessary parameters (sampling time, direction and upper/lower limit values + KP, TI). My input PID_Par is array of 25 points (in manual is written: "*1When auto tuning is not used, the same number of points are occupied as when the step response method is used."). For example, in GX Works 2, PID function works ok. Did someone have similar problem? Does someone have mitsubishi library (GW Works 3) with PID function that works correctly?   Regards Luka  
  10. Hello, Completely new to Mitsubishi PLCs and I need to use a date and time stamp for data collection purposes. We have a Siemens PLC as well and this has the data type "Date_And_Time" which is what I need to replicate. I have been attempting to write my own data type but am struggling with how to go about this as it is not straightforward and I cannot find anything about how the Siemens Date_And_Time is made up so I have nothing to go off. Does anyone have an example of a data type they have made that is the same? Or is there a data type which does this already in GX Works 2 that I just can't seem to find?  Please help!
  11. 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?  
  12. We have an iQ-r R08cpu that will not display some labels or addresses.  The PLC and the machine it controls run as expected.  However, when we read from the PLC, some of the labels and addresses are not shown.  Although it runs as expected, we are hesitant to make any changes or write to the PLC. There is a screenshot attached.  Any advice or solutions for this?
  13. FX3S not responding to HMI.

    Hi guys, I am an Electrical engineer on a cruise ship. I have a mixer (galley equipment) that is controlled by a FX1S-10MR PLC. It uses HMI F930GOT-BWD-E. Recently we found the PLC to be malfunctioning and replaced it with a new one from our stock. The new one is FX3S-10MR. Now, when i try to increase or decrease the speed via the HMI, the PLC doesn't respond; infact, the inverter just maintains a single frequency. The PLC is "supposed" to be pre-programmed by the manufacturer of the Mixer. I have very less knowledge of PLCs and sorry if i come across as stupid. I have been reading a bit lately. Do you think it would work if i can copy the program (from the FX1S PLC of another working mixer) by using GX works2 / GX developer software and write it on this new FX3S model ? What will happen if i change the type of PLC of this FX3S model to FX1S (just speculating since it's working find with FX1S). Today i tried to view the program inside this FX3S plc on GX developer and it does have a program. I am clueless though why it's not working with the HMI. Kindly, provide me with some guidance. TIA.
  14. Hello I have an old test rig (hydraulic cylinder applies pressure to a crank in sawtooth pattern) project written in gx developer for the Q03 plc. To this plc is connected a 1041 beijer panel, I have uploaded the project to E-designer. I am rewriting the sequence code because a new but similar test is prepared. Have a PID-block in gx works 2 (not in a simple project sadly) i would like to import  and use in gx developer. This is causing me some trouble though.  Can anyone tell me how to get the PID-blocks from GX Works 2 to GX Developer? Do you recommend me to upgrade the project to GX Works 2 instead? How will the panel react? I need to reprogram this as well. Cheers // Rolf
  15. After a recent update I am getting an error when I start GX works 2 and try to open a FX project. The error starts "GX cofigurator2-DP could not be loaded..."  Sometimes it can be clicked away, sometimes it just hangs. Now I am not using Profibus and have no plans to so why would this happen?  Is this bit of software hidden somewhere on the DVDs? Is this just the way it is now?   Thanks
  16. Mitsubishi GX Works Bugs??

    Hello I have been using GX Works 3 for a while now and I have discovered a couple of things, maybe bugs. I have not had any training for the software or hardware so maybe I did something wrong. 1 Labels. If you sort a global label table into any order other than the unsorted order that appears by default you are unable to create, delete or edit any labels. Our Mitsubishi representative discovered that if you click on the column header between 'Data Type' and 'Class' the order does not change but now editing is available. This, it turns out is a really bad idea. It seems the position the label was in when it was created is preserved, I think this is the unsorted order you get by default. If you sort the list and then delete a label it is possible that the label that should be in that position is also deleted. I have attached a small project to demonstrate this. Open the Global Labels notice the order they were created. Now change the sort order, click on the column header I described earlier to make them editable and then delete the label in position 1. For a while I thought this was the only problem but recently there has been a number of instances where I have created a label, given it a carefully selected address only to discover that it is being overwritten by another variable. I have not been able to work out exactly what is going on but I believe it is connected to the sort order of the labels. Also if you sort the order and change an address, have you changed the address of another label? The only solution I have found is to keep label tables very short so they are managable without having to sort the order, that is probably good practice anyway 1 Axis software limits. I have been using a number of axes in pairs, in incremental mode as caterpillar feeders, using FX5U-40SSC simple motion modules. I had a problem that the axis synchronised to follow would suddenly stop moving, the customer was having to power down the machine and start again. This problem persisted for months with Mitsubishi scratching their heads unable to fathom it out and ultimately stating that the problem must be in my code somewhere. It was suggested by the customer that it may be getting to a software limit, I showed the customer that the software limit was disabled in the setup and it was confirmed by Mitsubishi that it was not the problem. guess what, it is a problem. Once the actual position reached the limit of the double word memory it would stop moving. The solution is the take the servos out of synchronisation in order to set the position (datum) to zero every cycle. Unfortunately the drives do not always re-synch on the first attempt so you have to keep trying till it does, this now causes slight variations in cycle times but it works. Andy EDIT: I have since been informed that to disable the software limits they must be set to zero. This implies that the Enable/Disable setting is invalid and the limits are defaulted to their respective max values. Surely a default to zero would be more appropriate.     Label Test.gx3
  17. Hallo. Im hoping someone can shed some light on these topics. The company im working for have been using gx developer iec 7.04 for ages. The setup we have been using is QxUDE plc with beijer HMI and FR-E700 inverters on profibus. Recently(finally) we have been forced to start using gx works 2 because of newer plcs. With new software come new questions as always. And since im feeling we have been hanging in old software for too long. I want to make sure we are up to date this time. The setup we plan on using is QxUDV cpu, CC-link ie (QJ71GF11-T2), FR-A800 inverters and GOT 2000 for HMI I have made a few project in siemens and TIA portal. And software wise it has always annoyed me, that mitsubishi lacked the same integrated software package as siemens. This made me discover navigator. With system labels navigator makes the variable control, hardware setup and project overview im missing from siemens possible. My question to navigator is. Does people use this? i dont see much about it on the forum? is it already outdated? Gx works 2 or 3 Again i cant figure out what is new and what is old. What are the pros and con for choosing either? CC-link ie or CC-link From internet reading. I find that IE is the newest and faster CC-link version? Is the classic CC-link on the way out? If not why should i choose IE over classic? When setting up CC-link IE in navigator i dont get the same hardware in the catalog as CC-link. To setup inverters i need to user general intelligent device station. Whereas in cc-link i can choose FR-inverters. Is this the way it works? or can hardware catalogs be updated somehow? Blocks for FR-A800 Maybe its just me. but i really think the search function on the mitsubishi download page is crap. When i filter QPLC i get LPLC etc. ive been trying to find some blocks to control inverters without luck. Do i start creating it myself or can you point me in the right direction? I know these are a lot of mixes questions. But i feel we have been non-efficient for years because of bad software choices. Hope someone can shed some light one these points.
  18. A motor will be controlled by two switches.The Go switch will start the motor and the Stop switch will stop it. If the Stop switch was used to stop the motor, the Go switch must be thrown twice to start the motor. When the motor is active a light should be turned on. The Stop switch will be wired as normally closed.
  19. GX Works ARRAY usage

    Hi ALL! Do not compile project on GX Works: Type mismatch? But type is match!!! Equivalent project on Delta ISPSoft compile OK: What wrong?
  20. Help with CC - Link IE Field

    Hi Im working with an iQ-R CPU wich controls 6 conveyors with a CC-Link IE Field Network, the CC-Link module is a RJ71EN71. Each conveyor has a remote I/O (NZ2GF2B1-16TE Digital outputs main module with a NZ2EX2B1-16D extension for Digital Inputs). The communication in the CC - Link IE Field diagnostic appears to be OK, but I can´t send or receive IO signals from the Batch Monitor of Gx Works 3. Thanks for your attention!
  21. Hi everybody. I'm just getting started with GX Works 3 and I feel a bit lost. If I have an external help file for my function blocks, how do I register this in the program? I can't find it anywhere when I double-click the fb library or in the e-manual Viewer. The file format is .CHM and I have imported this to GXW2 earlier.   /Niklas
  22. Hello, I'm trying to use Mitsubishi GX Works 3 version 1 for the first time and get a 'memory is insufficient' error window when I try to open/start a new project or if I try to open a PLC project a co-worker made. I am using Windows 10/64-bit, company we purchased the software from says they are using it on windows 10 without issue. I get the error with no other programs running, have 6 GB RAM, and have 90% hard drive space available. I have monitored Task Manager while opening a file, RAM usage seems fine, and have tried opening with "Run as storminess".  I have tried uninstalling the program using the window "uninstall or change a program" - is the a different way to uninstall this program that will wipe it more completely? The install CD has Disk1, Disk2, Disk3(DocFX) sub folder , Support folders - I ran the .exe file from all 3. Does anyone have any suggestions? I am able to open an HMI project in GT works 3 without issue. I attached a screen shot of the error. Thanks so much!!
  23. hi.  i want to make some program that work with indirect adress. example, i make program with many much type. I make with Got-1000 mitsubishi.   can you bring me some example? i am sorry, my english is Bad
  24. What happens here? L06 / Gxworks 2

    Hello I am at a loss here. There is something happening with TON_2 that also affects the variable STEG. Even though the input to TON_2 is false, IN and Q are true. Suddenly IN and Q turn false, and at the same time variable STEG makes a jump from 3 to 4, even though criteria for this step is not confirmed. Have had to override this fault by introducing a SR-latch and outside of block make a comparison between NIVÅ_FÖRRÅDS_KÄRL and 150.0 By the way, TON_2 is not declared globally. Would be very happy for suggestions and pointers. Cheers // DAN PE2 Jump.avi PE1 Jump.avi
  25. Label Help

    I am using GX Works2 and I cannot use the format "Label.1" to access the first bit in the word represented by label. Is this a function that just does not work or is it abnormal. Is there a way to do this easily. I am using structured ladder. Also is there a way to use the K*, notation with an array of bools represented by a label. I saw elsewhere the syntax K8<Label>, but that will not compile for me.
