PLUS+1 Compliant Hardware / CYPR1 LED light meaning
« Last post by K_Bowen on September 08, 2023, 04:03:32 PM »
Does anyone know the meanings of the CYPR1 LED lights, including their combinations or can point me to some documentation that provides this information.  I've read the currently available manuals and tech sheets on the Danfoss website and those from the Guide program and none of them mention the lights at all.  I know/believe flashing green means it is functioning normally but that comes from observation and not any written documentation.

Any information would be appreciated!
Thanks!

PLUS+1 CS Hardware / CS100 & CS500 firmware update.
« Last post by Tor on September 07, 2023, 09:30:47 AM »
Hello

Microsoft has mandated a change in certificate authority for the Azure IoT Hub. For our connected solutions product, this means it’s necessary to upgrade from the factory firmware in order to keep remote communication to our telematics devices.

Actions:

•   CS100 update to firmware v170 or higher
•   CS500 update to firmware v114 or higher


Highlights:

•   Deadline for update is September 15th 2023.

•   Both CS100 & CS500 require firmware updates


What it means for Danfoss Customers:

•   Update status will be available on the Portal when initiated.
The following information will be displayed on the Device details page under Remote firmware update status:

(See Image Progress.png below)

Note: Orange refers to a “manual customer process”, Blue refers to “in progress”, and Green refers to “successful completion.”

•   Devices not upgraded by September 15th 2023 will lose the ability to be remotely upgraded in the future.

•   Devices not upgraded by September 15th 2023 will lose the ability to communicate with the PLUS+1 Connect platform in the future.

•   After September 15th 2023 it will only be possible to update the devices via local Service Tool connection.

•   Firmware for CS devices will be available on the Update Center.

•   When possible, it is best to use a local connection to update firmware to minimize effects of cellular disruption.

•   When possible, use CG150 instead of FOTA (Firmvareupdate Over the Air). CG150 takes max 3 min while FOTA can take aprox. 30 min.

•   If using cellular connection, make sure to have a good network before you start.

General controls / Re: How to Achieve an Exponential Curve from Linear Input

Hi,
I use X2 curves. This is very good for joysticks.
And you can change from linear to X2 by a parameter.

Thank you for the recommendation and for sharing your code!  I will give that a try.

Controllers / Re: Non-volatile memory MC controllers
« Last post by FluidPowerTom on August 30, 2023, 06:24:19 PM »
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 »
Hi,

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
« Last post by A.Fitz on August 29, 2023, 02:18:49 PM »
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
« Last post by A.Fitz on August 28, 2023, 08:00:07 PM »
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?
