Utilize project only allows me to select another GTW project, not the GTX project from my GOT2000
-
Does anyone know a way to convert GOT 2000 screens to a GOT 1000?
-
Downgrading because I am trying to copy the screens of an existing system to create a new one, but we parts bin shopped and I have 4 GOT1000's to use.

I have a feeling that I know the answer, but wanted to check for confirmation. See attached for a quick example of what I am talking about. New machine has a SM410 .1s flicker to a INCP to count time passed and stop a conveyor. I think a H Timer would be more precise but without knowing the deep insides of the PLC I can not be sure. In the code i have done a test where I have 2 H timers that are .2s longer than set time, I use the longer one to compare where it was when the flicker triggers the stop, and it does vary

I came from using Yaskawa and Omron PLC, and learned the mitsubishi in about 6 minutes. One look at the Insert menu will show you every keyboard shortcut you will need

Solved. CC Link between 2 CPU, data in buffer but fails TO/FROM
WattUp replied to WattUp's topic in Mitsubishi
Winner winner. After 1 hour going through everything again I found that issue. The second PLC card is setup and addressed as 200, but the TO/FROM command required it be H20 and always require to drop the last 0. -
SOLVED> Machine builder installed a terminating resistor across DA-DG instead of DA-DB.

We have a new machine that we are trying to get setup. We are having a strange symptom that we have never seen. Every 8-10minutes the Entire CC link network will drop off shutting everything down. At first we thought it was the 24v dropping, but have eliminated that now with our meter. I ran a CC-Link log and it does show every single station come up in an ‘Data Link error’.

That kinda looks like the panel was assembled wrong. There is no was to mirror like that in the settings.
-
Sorry for the delays. This project was actually removed from the line, and shelved. I will try and get it powered up to get this information
-
Sure, I will try and get that for you today.

This is more general topic, but I think the brand specific forums get a lot more traffic. And since we only have Mits PLC in our plant this fits best. When you are quoting a new machine, do you have some form of default PLC program that you can give to suppliers to use as a base point? Or do you simply learn the program as its given to you for each machine? Also, how detailed of a standard parts list do you have? This is another part of the process I find our plant to be severely lacking.

FIFO program examples for Mitsubishi PLC iQ-R R04CPU using GX Works3
WattUp replied to ALMAR's topic in Mitsubishi
I personally just use BMOV , MOV. I have seen maint techs get confused by FIFO before but setting it up with BMOV and MOV they seem to understand. BMOV D1000 D1001 K10 MOV D10 D1000 -
If you are hoping to use it like an index pointer those are Z. MOV K10 Z1 MOV D0Z1 D1000 :: Will move D0(+10)=D10 > D1000

I think i am going to create a similar solution to @Mitsm83, a spreadsheet with addressing scheme and a small sample program of how we like stepper logic and faults. Perhaps an HMI design template also.
-
You were understanding correctly, I am looking into creating a basic PLC example to give to suppliers for them to base off of. Our machines are all 100% custom applications, developed by integrator both in the US and Japan. The integrator is available during the initial machine start-up, but then myself, and my Maint team are responsible from there. Initially this came up because we had a new supplier that felt like they were trying to show off by making code overly complicated, either that or they had a very limited knowledge of the Mits functions. So we thought we would create examples that could be used to build on; basic stepper logic, faults, and even some standard HMI design
-
That is what we have done in the past, but I was hoping to build a better process for going forward.
-
Thank you so much for sharing your experience. This is exactly what I am hoping to achieve
-
This is exactly what I am looking for. Do you have an dedicated example program that you send also? One that is mocked up for all your spreadsheets?
-
No problem. I know it took me a while to get this running the first time, so I am happy to pass that along. I am so used to being a quick Google search away from any answer, but this industrial/PLC/Robot stuff just isn't all there yet. If i want to tear down a 1960's washing machine there is a youtube video of it, but getting a MITS to talk to a Motoman robot.. ugh.. 20 hours of research.

Every model number has its own program. Its a 4 step process to change camera jobs. 1. Set which SD Card the job is stored on [MOV K1 D102] 2. Set what job number you want to load [MOV SD200 D104] 3. Set camera Command code for job change. [MOV K24 D100] 4. Trigger Camera commad [Set D2.0]

Those are the two that I used to get it working. I did a little searching and found you this though. Edit: I guess this is still serial.. I know i had an ethernet one.. CV-X_MELSEC-Q_PLC-Link.pdf

GX works 2 - Special Relay (SM_ _ _) for a 0.5sec Pulse

Attached is a guide to all the SM _ _ _ Relays. SpecialRelayList.pdf -
I've been stuck in Florida from Irma but finally tried this on my project. Unfortunately, i get this error message after step 1c. I am offline with the PLC for testing though, so I am not sure if the error is because of that or from the project already being broken from the Navigator program.
