SSI absolute encoders and analog servos

There is not (as far as I know) a real-time Modbus interface to LinuxCNC HAL.

And encoder feedback is one place where you really want realtime.

Hi,

Ok so I will stick with original plan. Is there a bit file for 5i25 + 7i74 + 7i83 combo? I installed LinuxCNC on this laptop and downloaded 5i25 firmware files from Mesanet. But I cant see how to make this kind of configuration. Also selecting config with 7i74 gives me following error:

PNCconf encountered an error. The following information may be useful in troubleshooting:

Traceback (most recent call last):
File "/usr/bin/pncconf", line 2891, in on_mesa_component_value_changed
self.set_mesa_options(boardnum,title,firmware,numofpwmgens,numoftppwmgens,numofstepgens,numofencoders,numofsserialports,numofsserialchannels)

AttributeError: Data instance has no attribute '_sserial6_signalfilter'

If you post that last message to the Pncconf section hopefully Chris will see it.

Has bit and added source files for a 5i25/6i25 8xSSI+8xSSerial config for a 1 or 2 7I74s
(4 SSI+4SSerial per 7I74 SSI channels first on 7I74 (0..3), SSerial last (4..7))

Hi,

Ok this is what I need. Does this work with Pncconf or does that need XML file also? I need to make an order for cards asap Thank you

I dont think there's much hope of this working with pncconf
