I don't think it's possible to directly control the PVG actuators with a remote control, as far as i know you still need to program the logic in the microcontroller. But increase/decrease IO? aren't the PVG valves controlled with CANbus?

Controllers / Joystick with Duty output
« Last post by sverreo on June 20, 2023, 06:22:37 PM »
I have a joystick that output a 5V 500Hz Duty signal.

Can anybody explain how the duty input on f.ex. C1p16 on an XL104 work and should be setup?
I looked throug the API, but it doesn't give a thorough explanation.

The settings that work best for me is:
Bias = 3: Pull-Down to internal GND, Pull-Up to internal +5V
Range = 0: 5,25V range

Are the DigThresHigh and low settings applicable when using duty?

I say those settings work best for me, but i have had insidents when suddenly the input can't read the duty signal and only oscillates between 0 and 100% in the servicetool when i know the duty is 50%

Thanks, JordyHV. I hope to purchase as close to what I think I will need and start developing. The only thing I am not sure is if I am using a Danfoss remote control, does the receiver command the PVG actuators directly. Or does the receiver communicate to the microcontroller. (Or both) As this will increase or decrease the I/O required on the MC024?

you could definitely use the ports the way you described below, you're also able to mix Danfoss and non Danfoss components on the same bus if you want(although not recommended with an engine).

As a sidenote, if you are planning on using CANopen, there are standard function blocks for it in Danfoss, but its very basic. the standard J1939 function blocks are more user friendly and advanced.
So my recommendation is to use J1939 if possible! :)

The connectivity of all Danfoss devices in the Plus+1 ecosystem is exactly what has attracted me to use it. My system is currently a group of devices from multiple manufacturers and it is a headache to get them to communicate.
I am looking for MC0xx devices with two CAN ports if the Plus+1 devices are say for example on CAN0+ & CAN0- could the engine then use CAN1+ & CAN1-?

If you are going to use a seperate PLC for logic control you're not going to find this problem, the microcontrollers in my experience run very stable between 8 and 10 ms. and yes, they would be seperate nodes on the same CAN bus. I think that's the advantage of using PLUS+1 that there are standard blocks for most if not all danfoss components that you drag, drop and connect. Just be beware that those blocks are pretty heavy and fill up the micro controllers pretty fast, for example a project i worked on has a SC micro controller with like 14 valve sections and a few inverters and the micro controller was getting quite full.

Thank you, acmall and JordyHV.
The loop scan time may be a problem, but I will test this out in the R&D stage. Thank you for your suggestion.
So if I were to use a Danfoss remote control receiver, DM700 HMI, MC024-130 and PVEA-CI and PVEO-CI Series 6 Electrohydraulic Actuators. All of these would be nodes on the same CAN bus?

good to know indeed, thanks Acmall. i normally use the danfoss gateway adapter myself to do initial install, but i normally setup the ethernet port and use that later on to save time, but using the USB port would save a lot of money.
And yes AutoPile, those are the IOModules i was talking about.

my experience with using the HMI as a PLC aswell is that the normal loop time is roughly around 10-12 ms, but when i start navigating trough the screens it fluctuates up to like 40 ms, so if that's not a problem for your control loops it might be another cost saver! :)

Also note that most of the displays can be connected to via USB for programing. Upload times to the display are a lot quicker when connected via USB especially if you have a program that uses a lot of images or other files. The display can also act as the gateway to connect to any other Danfoss controller that is connected to any of the displays CAN ports.
