I am not sure if this is a good idea but you could try using a Fixed Scan program (which uses a timed interrupt) and you can set the Interval Setting to 1ms:   CPU Parameter/Interrupt Settings/Fixed Scan Interval Setting/Interrupt Setting from Internal Timer/I31     (or replace I31 for I30, I29 or I28 depending on which is assigned to your fixed scan program). This way your fixed scan program will trigger every 1ms and you won't need to create a timer. I think that you shouldn't put too much logic in this program or it will bog down your CPU and cause some overlap. You need to make sure your fixed scan program executes well under 1ms and leaves enough of the time slice for your main logic program/s to run.  I cannot test this method on a live PLC right now but it works in simulation with an extremely simple program.  Hope this helps

Hi, I am trying to use the CPU Module Logging Configuration Tool and need to open the GX LogViewer. When I try to open the LogViewer, I get the popup message saying "GX LogViewer has not been installed. Download it from the MITSUBISHI ELECTRIC FA Global Website". However, even though I am logged in to that website, I cannot see how to download GX LogViewer. There are many other software packages to download but not that one. Does anyone know how to go about downloading GX LogViewer? Kind Regards, Oliver  

Hey I just saw this post. While it is quite possible that the previous responses are correct and you are out of luck, if by "Newbie" you mean completely new, you may not know what would be obvious to someone who isn't as new so I will add the following (Sorry my screenshots were with the Write operation, this should be "Read"): Make sure you read the "Comments" from the PLC if there are any: Sometimes they are not in the Program Memory but in the Standard ROM so check for "Comments" in the "Standard ROM" section (changed by dropdown menu): Check that the comments are turned on in the GX Works2 menu Hope this helps. Cheers

ok, so it looks like I need to increase the memory allocation before adding the module labels for the RJ71EIP91 module... 1) Increase local label area capacity 2) Re-Build All 3) add label for RJ71EIP91 4) Add the input and output data FBs to the project 5) Program away (Maybe rebuild all again first....) Anyone feel free to correct me if I am wrong.      

@titanspark76 thanks, that looks like it would reduce the complexity of dealing with the data read into the PLC by a lot. The only problem is (possibly due to my relative inexperience in Mitsubishi PLCs) now after adding this to my program I have a memory problem and cannot build my code. First I get the "Program Conversion" Error "Necessary local label area capacity is insufficient in the label of program..." (Error Code 0x12121042) Which takes me to the Label Area Capacity  settings. So I change the 0K to 40K but I still get the same error. If I try to increase above 40K I get the popup which starts: "(Standard) local device area capacity lacks xK word." (where x is the number I entered minus 40 in the local label). This takes me to the Internal Relay Local Device Start configuration (I think it wants me to increase it from 0 to xK but I am restricted to specific values...?). My internet search so far doesn't show any solution to this problem. Do you know what I may be doing wrong?  

Hi All, I need to start PLC Data Logging using an SD card in the CPU module for an iQ-R PLC.  I have not attempted this kind of logging before and I was wondering about any restrictions on the type of SD cards that can be used. The documentation I have found says "SD/SDHC memory card: 32Gb maximum". Does anyone know why can't I use a 64 GB SD card ? (maybe due to addressing limitations?) Also, when I look for SD cards, I see different speeds of data transfer such as 120 MB/s or 100 MB/s and I was wondering if there is any difference as far as the logging is concerned.  Does anyone know if there are any other restrictions, brands that don't work? Useful tips? Cheers    

I believe there you can use SoftGOT2000 option in GT Designer3. I haven't used it but the Mitsubishi website makes it sound like it is what I understand you are looking for. https://www.mitsubishielectric.com/fa/products/hmi/got/pmerit/sgt/sgt2000/index.html The only reason I haven't tried it yet is because it requires a separate license and we are using the GOT hardware units on site. From the new project wizard in GT Designer3 (GOT2000):     Hope this helps.  

Thanks IO_Rack I appreciate your response. What I was getting at with the comparison to Allen-Bradley is that in Allen-Bradley PLCs you would install the EDS file or AOP and then add the IV3 camera to the I/O tree and voila! you have tags to read and write to as long as you put in the correct IP address and everything is connected, whereas in the Mitsubishi PLC as far as I can see so far: You have to first use the Ethernet/IP Configuration Tool for RJ71EIP91 software (which is separate from GX Works2/3) to install the EDS and create or modify the configuration, including the input and output sizes). For reading/writing the configuration you have to connect to the EIP module (Not the PLC) and read/write the configuration. This should get the EIP module communicating with the IV3 if set up correctly but not the EIP module with the PLC.  You have to write logic for the PLC to read and write the data to the EIP module buffer memory... It seems you have to use the addresses starting at Un\G65536 offset by the addresses already used by existing devices for inputs and the same thing starting at Un\G196608 for the outputs. Then you have to look at the IV3 I/O registers and figure out which bits/registers will contain the values that you want. And for me, this means creating a big Excel spreadsheet to figure it all out and hope I haven't miscalculated and misaligned anything. Troubleshoot will not be fun. So the examples for Allen-Bradley PLCs are not really very helpful. Keyence PLCs are more similar to Mitsubishi PLCs but not the same. I haven't got to test my program out yet as I am still waiting for others to mount and wire the cameras but I am hopeful it works. Of course it is entirely possible there is a better way to do this, but that is my plan so far.      

Hi, has anyone tried to get a Mitsubishi iQ-R to communicate with the Keyence IV3 series cameras over Ethernet/IP?  There are videos about how to use the IV3 with Allen-Bradley (Rockwell) PLCs but Rockwell's implementation of EIP is completely different from Mitsubishi's implementation. I am using an existing system with the RJ71EIP91, I have the IV3 EDS file added to the Ethernet/IP Configuration Toll for RJ71EIP91 software, I know I need to add the IV3, set the IP address and connection number. But how do I access the data, and send the trigger for the IV3? The instruction videos for Allen-Bradley uses the I/O tree to create tags and pre-made AOI's to create the logic to do all of the communication work in the PLC code, which is a process that I am familiar with. However, none of that is relevant to the Mitsubishi PLCs.  I figure I have to use somethning like Uxx\Gxxxxxxx in my logic to access the data for the IV3 from the RJ71EIP91 module but not sure how to get that to and from the actual IV3. Does anyone have any ideas? (sorry my initial post was blank, accidentally prematurely posted).        

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  

Hi All, I am trying to use Toyopuc PLCs for the first time and having some trouble.  The manual shows a Global Tag List, Local Tag List and the capacity to create tags etc. Manual for PCWin2:   My PCWin2 looks completely different:   Also I cannot change the CPU - it is stuck on Nano 10GX. Even when I create a new file. Does anyone know what I am doing wrong?   Any help is appreciated.  Thanks.              

Yeah, silly me...I though the person designing the screen got to decide which object goes where, especially when seemingly offered the option to do so...But I guess any software package is annoying when you don't know how to deal with its quirks. I am getting there, it seems I have this one figured out. On to the next one...

Thanks but no change. Still no "Stacking Order" functions work regardless of Graphic version. However, I did finally get it to work. I had to turn on the Lamp Feature/"Use lamp attribute" check box on the rectangle and put SM400 to make it always ON:     Then the rectangle started to behave in accordance with the Stacking options...I don't understand why this is but it will have to do for now.    

Under System/Type Setting I am seeing: Graphics Setting: GOT Graphic Ver. 1  

Hi All,  Does anyone know how to draw a simple "Figure" such as a rectangle and put it on top of an existing "Object" in GT Designer 3 (GT2000)? This sounds easy and I can do this in any number of other HMI software packages but Mitsubishi GT Designer3 doesn't behave like other HMI packages and it doesn't work by just grabbing a rectangle, having it occupy the same 2D space as the existing object and clicking "Send to Front", or "Send to Back" etc. For example, below is a screenshot of a Bit Lamp and a rectangle. I sent the Bit Lamp to the  "Back of the Back Layer" which to me means it should be hiding behind the rectangle. I also sent the rectangle to the "Front Layer" and the "Front". Either of which should cover the Bit Lamp. Doesn't work.....Very frustrating.... Does anyone know how to make this work? Thanks
