General controls / Re: How to Achieve an Exponential Curve from Linear Input
« Last post by Marbek_Elektronik on September 05, 2023, 05:06:30 PM »
I use X2 curves. This is very good for joysticks.
And you can change from linear to X2 by a parameter.

Controllers / Re: Non-volatile memory MC controllers

Yep, it is as you say that all of the MC0xx-1xx controllers have the FRAM.  I'd still recommend using rising edge logic for writing to EE memory as a best practice.
Controllers / Non-volatile memory MC controllers
« Last post by sverreo on August 30, 2023, 10:18:04 AM »

Just a question, i think i haven't been paying attention :)
Have the MC0xx-1xx controllers all have FRAM memory since they were upgraded from MC0xx-0xx?

From the Technical manual BC152986484529en-000701:
"FRAM used in the MC0XX-1XX controller, is rated for 100 trillion read/write cycles per sector."

I always thought it was 1million cycles on the MC controllers...

I have had confirmation from Danfoss support this as a bug that the development team have fixed in the next release of Guide.
General controls / Re: PID tuning with a delay

Hey thanks for the input! That gives me a few things to experiment with.

We are controlling a gate which allows material onto a conveyor belt, and measuring the resultant fill level of a bin.

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?
PLUS+1 GUIDE / Re: .EDS files in GUIDE

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

PLUS+1 CS Hardware / Re: CS500 Firmware update

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.
