  1. 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  
  2. 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.
  3. 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
  4. 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
  5. 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     Label Test.gx3
  6. 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.
  7. 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.
  8. 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?
  9. 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!
  10. 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
  11. 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!!
  12. 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
  13. 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
  14. 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?  
  15. 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.   
  16. ST program step count

    Hello everyone. I can't find my ST program step count in GX WORKS 2. Does anybody knows where is program step count in GX WORKS2 ?
  17. Program Notes & Comments

    I used to use the Old Dos based MEDOC very many, many, years. I havn,t programmed for years now. We have GX Works 2 at work, and I am practicing programming an FX 3G - 40M to try and keep my hand in. Allthough I can write and read the program ok, the PLC keeps saying that it has no memory for the comments. Apparently the memory has to be set on the PLC. Any advice or information links will be appreciated
  18. Hello All! Long time engineer first time programmer. Any help is greatly appreciated. I have an automated Beer bottle rinser, filler, and capper that I need help diagnosing a problem. We purchased the machine in July and it ran great until a couple weeks ago when it doesn't seen to be reacting to bottles being present anymore. FX1s-30MR Here are the symptoms: When a bottle is run around the filling carousel, there is a prox sensor to detect it's presence (X007). There is also a sensor under the machine on the gears to detect timing (X006) When a bottle is detecting there is a slight delay, then the pneumatic valve for the purge fires (Y001), followed by the valve to fill the bottle with beer (Y002). Even though, the LED light on both the sensor and the I/O illuminate confirming that it is receiving the the input signal from that sensor, no output signals are being sent. My first instinct was to check all electrical connections and swap out the prox sensor just to be safe, but still no dice.... So I purchased a USB-RS422 FX cable and downloaded the demo of GX Works 2 to better try to pin point the issue. Using the monitor function on GX works 2 I can again confirm that the PLC is receiving the correct signal from X007 when a bottle is present, however the outputs Y001 and Y002 have a constant value of 0... Unfortunately this program is not simple enough for me to really understand, so maybe someone can make more sense of it than me. (see attached). Also, Not sure if its related, but when I ran the check program there is a double coil error revolving around the Beer inlet solenoid. This is to let beer into the filler bowl, not the bottle. oh and the manufacturer won't be able to help for a couple weeks when they can send a technician... Any thoughts, comments, or questions are appreciated. Cheers, Eric screenshot2.bmp screenshot1.bmp
  19. Software: GX Works3 I'm really struggling to understand GX Works online / offline operation. (I know they've been consistent in how this works for the past ten years - but it's consistently bad!) I can't find how to work in offline mode. I powered off the PLC and the software keeps trying to connect. I've cleared the PLC memory and am trying to download the complete program to an FX5U. (I was able to do it earlier. I'm still able to communicate with PLC over Ethernet.) I'm getting:Unable to write target file because it is the following status. (sic) - Unconverted - Converted function block does not exist in FB file. - Converted function block does not exist in FUN file. - Unconverted module label. There are no red items in the navigation tree. There are no errors after a Rebuild All command. What do I need to do to figure out what the problem is? Many thanks.
  20. Hello everybody, As many of you can see, I took a course onto development the user libraries, that able to simplify extremely a PLC programming process, to help programmers to increase a productivity of their labor, to reduce a program code and quantity of used system variables, to improve readability of programs. A part of libraries has been already developed and looks fine. Also I full with new ideas, plans and could design new and new that then to share these libraries with other programmers. The work is bringing me a pleasure, however, at current situation I can not allow for me to share the libraries for free. I can explain why. First of all, it takes my time, which is money, and I should feed my family, also the work eats a health, which is not infinitive. The second, those who can get it for free, will not appreciate the labor and will distribute it to the left and to the right. The third, ME has not an interest to my offer, to the products and doesn't want to help to make it available for all. What I'd like to propose to you: If you have an interest, I can offer to open a subscription to the ready and new libraries, which will be developed further. What I can promise and guarantee: I will collect wishes and requirements of subscribers and all can vote, what should be realized at first. The subscribers will can get a release with up to four small libraries or one big (for example, such like Modbus Master/Slave library) every month, that will fit to the requirements and the collective choice. What's a payment for the subscription? I suppose a fee in 100 USD per annum will not be predatory for a subscriber's pocket. The fee will cover costs in case, if the number of subscribers will exceed 70 people. Thanks to all for the attention and I'd like to offer to discuss the proposal in this topic.
  21. Hi, again. (I'm getting good support!) Every time I write to PLC it is switched out of run mode. I use Remote Operation to try to switch back to run mode but I get blinking P.RUN indication and blinking RUN light on PLC. I have to cycle the power to get back to run mode. Can I switch to run remotely?
  22. 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.
  23. ON/OFF Timer for Mitsubishi FX

    FB_TIMER_ON_OFF The FB is a part of RTC library and implements a timer, based on RTC, for ON and OFF a control bit, e.g. to turn ON/OFF a load in the time interval, and can be easily added into your program in desired quantity. The FB is supplied with E (Enable) input, EO (Output to Control Bit), and can operate in one of two modes: HMS = Hours + Minutes + Seconds (daily timer) MDH = Month + Date + Hours (yearly timer) Each setpoint of ON and OFF time settings should be represented as Array of INT [0...2] type and contain a time data according to the chosen mode. Thus, for example: - in HMS mode: a control bit can be turned on at 02:03:14 am and then turned off at 06:04:17 pm, or turned on at 05:12:27 pm and turned off at 07:06:22 am; - in MDH mode: a control bit can be turned on 3th February at 02:00 pm and then turned off 4th June at 05:00 pm, or turned on 12th November at 03:00 pm and turned off 6th March at 10:00 pm. If the values of both time settings are the same, the FB output will not be activated. Supporting PLC CPUs: All FX Program memory: - 34 steps per each FB instance - 4 steps for entire project (reading from RTC) System variables: M - 3 bits (for entire project) The library is compatible with GX IEC Developer and GX Works2 software . https://plus.google.com/105445006108716761629/posts/Z4v4F11s4Bz
