Hello Spark2u,

This issue is, as far as I know, fixed with version 1.0.192 of Update Center.
You can ask the customer to log in to the https://my.danfoss.com/ page.  If that works there might be other IT issues.

If the customer still have issues, please ask him to contact PLUS+1 Helpdesk, https://www.danfoss.com/en/campaigns/dps/plusplus1-support-form/.


Have a nice day.

Thanks for that. Apparently my inspector was hiding and once I enabled it a lightbulb came on in my head. Guess I got stuck in some tunnel vision.

Hello.

I recently got a JS1-H PWM joystick. It did not come straight from Danfoss since my client was very tight on time and we had to resort to finding a joystick from OEM instead of Danfoss. I had already prepared the Plus1+ Guide program for it and compiled it, I used the built in template as a starting point.
It was written in 2025.3 version and when I tried uploading the .LHX file this morning I got an error of mismatch. first image named Service_tool

So I updated everything to version 2026.1, updated the HWD in the project and when uploading the compiled code from that I get the same issue. (See picture called guide)

Tried creating a new project and using the template file and same results. Does anyone have an idea why I'm getting "(undefined)" on the new LHS despite it being created from a template for the JS1-H PWM?

Is it because of bootloader version mismatch, but why the "(undefined)" ? (see picture Comparison)

I will try to answer some questions and give more information that we have learned in the last few weeks.

Currently we decided to use math and my current control of individually controling the throttles and watch the loads and adjust by a step, in a stime period with a window, all values we can change on the display to tune the loading. On 2 machines now this is working really well.

To Clarify, the 4 CAT C32 are each hooked to a 5 speed transmission which then outputs to a gearbox that combines their inputs to 1 output. The gearbox is huge and requires two pieces of equipment or a very large excavator to unload and attach to the machine.

I am using a bunch of Danfoss controllers and IO to do this just due to how and where we are controlling everything. In the cab drive console I have a 24pin IO module reading the throttle knobs, in the electrical panel I have a MC090-10 which handles all the hydrostats, and a bunch of pressure transducers for the rest of the machine. On each pod is a MC050-118, a little over kill because we aren't recording any telemetry but we are using that on other stuff so it was simpler to keep using a computer we had on hand, plus it has enough outputs for the fuel, start and area light relays plus the 5 speed transmission coils. This MC050-118 takes my commands off the canbus and converts to what the CAT ECM needs for throttle and start and also relays engine info back to the cab displays.

We are inventing our own setup, nobody currently does what we do.

My initial PID ramped everything up and didn't adjust anything politely to say the lease. The new program we just threw on the second machine today is a very simplified version of a PID. We have the Position 1 load as the feedback and adjust 2,3,4 accordingly.

I am a jack of all trades, Electrician, Electronics, Computer programmer, Mechanic, Mechanical, Plumbing, Construction. When I work on our machines and anything with company or life or friends I help and can do virtually everything. Went to school for 1.5 years for electrical engineering, failed Chemistry and Calculus twice and lost my grant money. Got a full time job to make money and kept up my hobbies and experience doing electrical and programming to be where I am today.

Unfortunately the processes we run and materials we run every day, every foot of trench could be different than the next so there is not one load we always see. Today watching the feedback remotely I watched the load go from 35-45 for hours then up to 45-55 for a little while then back down to 30-35 until I lost connection. We have been able to keep the loads within 10% load of the master poisition 1 load.

Thanks for the feedback and questions and hopefully I answered your questions to make things make sense.

How does the gearbox work? does it require the same RPM from all engines or can they vary independently? the way i read your description it seems like they can vary.

Curious how did your initial PID work? 1PID or 4 (each engine)?
What's the setpoint, feedback and what is the output you were using.

From the information you've given my starting point would be to try having 4 independent PIDs, 1 for each motor.
The setpoint is your desired load/rpm/torque, feedback is that from the individual motor and the output is the throttle to that motor.
