Modbus error

[Socke]

I get the error function code 120 / 127 not supported.
Any hint, where I can find more info?
I see the communication counters counting up.

Where and when do you get this message? If using the Modbus plugin then what is the version of the plugin?

[Socke]

I‘m using uccnc 1.2116 and the Modus Master Plugin, that came with uccnc.

I get the error, as I start the loop with functions enabled. With functions disabled, I get no error.

OK, getting closer. In 1.2116 the Modbus plugin version is 1.6.0.0. But I still don't know what did you set in the functions. Could you upload your profile with the saved Modbus settings? Also, what is connected using Modbus?

[Socke]

I can't get a grip at the machine now, only in the evening. In the function i want to read coils, slave adress 1, starting register slave and uccnc at 0, everything like in the manual.
The slave is an I/O-board: https://de.aliexpress.com/i/1005005338884242.html

Thanks, I'll check it.

On Youtube press Share, select Embed then copy. This long string has to be between the youtube - /youtube.



As I see Battwell could control this beauty, so it's possible. I can't imagine how he could do it, because the manuals don't help too much...

[Socke]

So, what can I do but asking at YouTube and hoping for an answer?

[dezsoe]

As I wrote: upload your profile. It has your settings for the Modbus plugin, so I can compare it with the manuals and (hopefully) find the problem.

The modbus-part:

Code: Select all

Where can we play with registers?
Or is this the wrong profile-file?
