Danfoss have a youtube video tutorial for migrating from a DP250 to a DM4300

With the controllers i would i expect you will have to convert the MC038 code to a MC050, then that means reassign all the I/O in the login to suit to new pin configs.

Hi guys!

I've got a need to replace the target controller in the project: MC038 should be replaced by MC050, and in another project DP250 should be replaced with DM430E. The reason to replace is that MC038 and DP250 are not available any longer.

So, the question is how to do that properly. I haven't found an easy way to do that...

Thanks,
Alexey.

I have had projects with DP700, MC050 and MC024.
When I close one sub-project, I save the scs file of the project.
So, I can oben it in next poject and look and copy from oter project.
And yes, I copy also a table with can-comunication-messages from one project to another.
So, 3 controllers are easy to manage.

Yes, I see it exactly the same way.
Unfortunately, you have to program multiple projects, and you can't establish a connection between them in the Guide.
Only in the service tool can you access everything together.
Sometimes I work with two computers: On one computer, I program the display, and on the other, a controller.
Usually, the display is the master and sends commands to a controller to set outputs or even rewrite EEPROMs or query inputs, etc.
For fast processes, I like to offload the software to the controllers.

What I usually do is I have an excel file with commands listed over CAN and then have multiple guide files, each for each controller, there really isn't an easy solution to this AFAIK. It quickly turns into a logistical nightmare. Creating some flowcharts in draw.io helps with keeping my head sane when doing projects like this to memorize CAN nodes addresses and such. The only way to test this is as previous commenter made about using the service tool and hooking up a workbench to test the whole setup.

Please look to the BTS728L2  from infineon. I have opened  controllers and io-modules and find this as output MosFet.
There are to MosFets in one IC.
Because of temperature the maximum load current is 6A (4A at 70°C) (both channals together.)

There is no difference between PVG Pwr and only DOUT.
 For example look at MC050-110: Here is C1p33 and c1p34 one IC!
(C1p31 and c1p32 are one Power Switch für example! and so on!)
C1P31   DOUT
C1P32   DOUT

C1P33   DOUT
C1P34   DOUT/PVG Pwr

C1P35   DOUT/PVG Pwr
C1P36   DOUT/PVG Pwr

C1P37   PWMOUT/DOUT/PVGOUT

C1P38   PWMOUT/DOUT/PVGOUT
....

If you power PVE Valves you have to consider the capacitors in it.
Older PVEs have had a big capacitor. Since about 15 years the capacitor is lower.
The smart Power Switch have to power the capacitors and the current protection should not turn off. Thats the reason.
Danfoss have to tell us, what is the maximum number of valves.
