General controls / Re: PID tuning with a delay
« Last post by FluidPowerTom on August 29, 2023, 01:27:02 AM »
I've done plenty of PI / PID loops with Danfoss controllers but not something with such a long delay in the feedback.  Does the gate just move very, very slowly, or does it actually take 30 seconds before your controller is sent the position of the gate?  Does it get new feedback every 30 seconds only, or is it continuous feedback but 30 seconds delayed?

The PID loop has a sample time input, and the highest value is 32,767 ms.  So, haha, perhaps you just put 30,000 in there?  I wouldn't expect that to work very reliably, but it might be worth a try for fun.

If this truly is a case where the cylinder moves, and your controller won't know it moves for 30 seconds then you'll need to consider other system dynamics.  Fortunately, since it sounds like position control you're probably only dealing with P-gain which is not time based.  If the signal to the valve doesn't change for 30 seconds is that long enough that you could overshoot your setpoint significantly?  Worst case scenario is perhaps you are right outside the tolerance for your setpoint, and your loop thinks the gate is where it was 30 seconds ago.  In that scenario how far will the gate move in 30 seconds?  Can you limit the speed to where in 30 seconds you will not have overshot your setpoint?  If not then perhaps you'll need to oscillate your valve signal on and off with the on duration set to result in a cylinder movement roughly equivalent to your position tolerance.

That's probably how I'd start out.

General controls / PID tuning with a delay

We have been asked to implement a PI / PID loop on a cylinder controlled gate, but the feedback is delayed by about 30 seconds.
I assume this will cause some issues with tuning and operation of the system.
Has anyone done a system like this with a Danfoss controller?

Is there an update on this topic or when can we expect the implementation of the EDS files?

For me, on three machines, only one is updated.
The firmware version number to be upgraded to 114.

But, we had a CAN problem during the update. I had to reboot by the wired service tool.
Since then, I can no longer connect with the interlink remote.

After you did the update was the version string updated to the new version? We are seeing the device go through the 5 step FOTA process from the device details page and then show as completed. The device firmware value does not update to the new version though. I have logged into the device using the remote interlink and it also shows the application version has not updated. Almost like it did not update at all.

Thanks for your response.
Yesterday, I did not have access to the firmware update :

Today it works properly. I was able to do the updates.

I was told it can be done using the connect portal, or a remote download using the remote interlink gateway. I was also told there is not a preferred method. With that being said, I have had zero luck using the remote interlink gateway to update the CS500. Remote download fails after about 10-15 seconds every time (download request failed). I attempted this on multiple devices as well to rule out a bad cell connection or something of the sort. I have had some success using the portal. Only a couple devices seem to have hung up on either "Requested" or "Downloading" so far.

I have 56 devices to update and so far have attempted 8. 4 of the 8 show as "completed" the other 4 are showing as "Downloading" or "Requested".

To update using the connect portal, first login then click on the devices tab in the left side bar menu. From there under your list of devices you will see an icon that is 3 vertical dots. Click on it and then click device firmware update. Once you select the firmware version you want to update and click apply you can view the status from the device details page (magnifying glass icon from device list).

Hope that helps.

I receive a Product Information Bulletin for new version of CS500 firmware.
How to update CS500 firmware remotely ?

Thank in advance.
Displays / Re: DM1000 not displaying all images
« Last post by acmall on August 15, 2023, 09:08:02 AM »
I have the same issue with Guide 2023.2, the previous version 2023.1 is also ok. Fortunately I had a backup of the project as was able to go back to 2022.4 easily. If you don't have a backup you may be able to export the screen definitions, import them into a new project and copy the code in from the module viewer.

It will sometimes compile all the images and work ok. You can tell by checking the size of the __imageX.c files that are created in the project directory when compiling. If any of them are below 1kb it will most likely be a missing image.

Displays / DM1000 not displaying all images
« Last post by mfaber on August 15, 2023, 08:10:47 AM »
Hi, I have been using a DM1000 display programmed with Guide 2022.4 (and below) for a few months without any issues. I have recently upgraded Guide to 2023.2 and now some images do not show on the screen after loading the compiled code to the DM1000. Each time I compile and load it is a different set of images that doesn't show on the screen. Seems random each time I compile. The touch area for where the image should be still works but the image is gone. I have tried to revert back to Guide 2022.4 to resume normal functionality but the project will not open since it was saved last using 2023.2. Any suggestions? Is there a way to revert the project back to 2022.4? This must be a bug for Guide 2023.2?
