Hi Endian:

Thanks for your reply and sorry for the delay in responding, it completely slipped my mind...

The EL7221-9014 and ZB8610 modules have arrived, but I had to request the motor and cables. The supplier told me they'll arrive this week! I'm dying to have everything so I can start working! I think I included homing among the capabilities of the EL7221-9014 module in my previous description, and it's true what you said, the module doesn't hom, although it does have probing. Regarding the latter, it's not absolutely necessary for me; I'll use LinuxCNC's homing. What I would like, as I explained before, is to use the module in speed mode with its internal control...

As soon as I have everything, I'll start testing. I'll update you. Regards and thanks.

Yes, too old to run MODBUS which requires a PktUART version >1:


hm2/hm2_5i25.0: inconsistent Module Descriptor for PktUART Transmit Channel, not loading driver
hm2/hm2_5i25.0: Version = 3, expected 0


Also with this firmware there is no sserial port 1
(all channels = 0..7 are port 0)

I am starting this thread to seek information and guidance, with the hope that it may also serve as a helpful resource for others facing similar challenges.I am currently considering retrofitting my machine as the most practical option, given the scarcity and high cost of original replacement parts. With that in mind, I would appreciate any advice on the best approach to begin this project.

Firmware flashed without any errors. However, when launching my configuration, I receive errors.

Could this be because of the old Linux?

Or am I loading it wrong?
loadrt hm2_pci config="num_encoders=3 num_pwmgens=0 num_stepgens=0 sserial_port_0=000000 sserial_port_1=00000000"

Terminal output:

Thanks a lot for your time and support!

That's absolutely right; I'm trying to get it to look like your screenshot, but everything is on the same plane for me,

 

5i25 bitfile for 7I77 on P3, 7I74 on P2
2 PktUARTs on 7I74 channels 6 and 7 (PktUART channels 1 and 0)
7I74 channels 0..4 = sserial port 0 channels 3..7
(two sserial ports wont fit with two PktUARTS on a 5I25 but using one sserial port
only loses one 7I74 channel)

Thank you for the clarification! That actually works out perfectly for my setup.

Since my Modbus VFD needs RS-485, I will use Channel 7 for that.

I also have a custom remote pendant (already come with cnc) that uses full-duplex RS-422, so I can use one of the RS-422-only channels for that.

Could you please compile a 5I25 bitfile with the following configuration?
P3: Standard 7I77
P2: 7I74
Channel 0: SSerial (for my 7I84)
Channel 1: SSerial (for my 7I70)
Channel 2: SSerial (for my 7I71)

Channels 3-5: SSerial (or unused)

Channel 6: pktUART (RS-422 for the Pendant)
Channel 7: pktUART (RS-485 for the Modbus VFD)

Thank you so much for your time and support!

Frage den Verkäufer, ob er dir die Dateien über E-Mail zusenden kann.
Ich habe alte Zugangsdaten für den Baidu Link Downloader gefunden, er will jetzt aber 3$ dafür haben.
Im Ordner ist eine Datei "F7I98 source code.zip". Darin ist vermutlich alles, was es für die Bitfileerstellung mit Xilinx ISE braucht.
Wenn er dir das zuschickt und du das ISE heruntergeladen hast, ist es nur copy&paste + ein Doppelklick, um das Bitfile zu erstellen. Eine weitere Karte würde ich wegen vorhandenem Bitfile allein nicht kaufen.
Poste den Zipordner hier, dann probiere ich selber das Bitfile zu machen.

I don't know if this helps, as i am usually wrong. In a project with tkinter yesnobox, thats the first lines of the python file

The 7I74 can only support 1 RS-485 channel (channel 7) as channels 0..6 are RS-422 only

You can use the serial port on the 7I77 for RS-485
 

I was wanting to revisit this, and tried to make it work with the current version of linuxcnc, but it seems that the switch from Python2 to Python3 has rendered the python remap script non functional.

At first Linuxcnc wouldn't even start. But with clues from error messages I changed the 4th line from:to:
And that got the config running again.  But it still doesn't work right and now there are no error messages.  The input window opens, but it is completely empty except for the OK button and the title doesn't show in the title bar.  So at least a little of the Tkinter is working, but not most of it.

I am retrofitting an old Morbidelli CNC woodworking machine. My old setup used analog 0-10V to control the spindle inverter, but I would like to switch to Modbus RTU using an unused channel on my 7I74 card.

I checked the standard Mesa firmware archive but couldn't find a bitfile with the pktUART module for this exact hardware combination. Could PCW or someone else kindly compile a custom bitfile for me with 1 or 2 channels of pktUART on the 7I74, leaving the rest as standard SSerial?

My current hardware configuration is:
5I25 (P3) -> 7I77
5I25 (P2) -> 7I74

• 7I74 (Channel 0) -> 7I84 (inputs/outputs)
• 7I74 (Channel 1) -> 7I70 (inputs)
• 7I74 (Channel 2) -> 7I71 (outputs)

I need channels 0, 1, and 2 to remain SSerial for my existing expansion boards. If channel 6 (or 6 and 7) could be configured as pktUART for the Modbus VFD, that would be perfect!
Thanks in advance for the help!

Da es für die 7i92 mit dem Benezanbitfile schon was passendes gibt, wäre ich auch am schauen nach einer 7i92, da sollten ja die originales Bitfiles draufpassen. Die hier würde mir vorschieben.. de.aliexpress.com/item/1005010725599295....%7C_p_origin_prod%3A
 

Hallo! Wenn du dir die Mühe machen würdest eine Anleitung für das Bitfile zu schreiben wäre das Mega! Da muss ich mir überlegen was i h dir für einen Stein in den Garten werfen kann! Bild der Karte dauert leider etwas, ich hatte gedacht ein Bild angehängt zu haben, und aktuell gab ich keinen Zugriff auf die Bilder oder die Karte.. Der Link ist folgender : "pan.baidu.com/s/1e8-TJ5BXo_-pZYBvHPJc9Q?pwd=g7jh" .. Ich kann da nichts direkt runterladen, ich soll immer eine Software installieren, das hab ich auf einem alten Smartphone gemacht (ich bin da etwas paranoid), konnte aber nichts erreichen. Selbst mit zweitem Smartphone und Fotoübersetzer hats nicht geklappt..  Vielleicht bin ich einfach zu doof... Danke dir im voraus.. Gruß Thomas
