PDO variable 64 bit

Category: EtherCAT

No that is not possible. BitLen refers to the ethercat data. It is 32-bit. It is what the device gives out. That's what I tried to make you verify hehe.
You can not change that to 64-bit, it is 32-bit. Device specification.

The line I showed, which is your first line, is ok. It makes a hal pin of type 64-bit float (or double as it is called) from 32-bit integer data from your device.

An alternative is to not make it a float, but keep it a 32-bit integer in hal is
<pdoEntry idx="607A" subIdx="00" bitLen="32" halPin="poscommand" halType="s32"/>

This can help debugging, and there are type conversion functions in hal to turn it into a float.

Hi PCW.

I´m working on it...

best regards

H.P.

UPDATE:
It´s finally done. Raspi5 with 7C80 is running.

instead of using the letter, use the joint number and see if this resolves! change the word axis: to joint: also

machine.home.joint:0
machine.home.joint:1
machine.home.joint:2
machine.home.joint:4
machine.home.joint:5

PDO variable 64 bit

Category: EtherCAT

so the possibilities of declaring a variable other than float are:

<pdoEntry idx="607A" subIdx="00" bitLen="64" halPin="poscommand" halType="float-sisgend" scale="838860.7"/>

<pdoEntry idx="607A" subIdx="00" bitLen="64" halPin="poscommand" halType="floa-ieee" scale="838860.7"/>

<pdoEntry idx="607A" subIdx="00" bitLen="64" halPin="poscommand" halType="float-double-ieee" scale="838860.7"/>
 

with bitLen = 64

it's correct ?

PDO variable 64 bit

It is already a 64-bit float or "double" as everyone calls it except in the ethercat-conf.xml file. Where it is called float.
Linuxcnc switched from 32-bit floats to 64-bit floats somewhere version 2.4 or so.

If this line works for you, then that is the best you can do.
<pdoEntry idx="607A" subIdx="00" bitLen="32" halPin="poscommand" halType="float" scale="838860.7"/>
This takes a signed integer from Ethercat, obviously the device's encoder position comes as a signed 32-bit integer. This is then converted into a halfloat, which is a double. I think this is what you ask for. All floats in hal are 64-bit doubles.

The conversions to float aren't named very good
"float": ethercat signed 32-bit integer to 64-bit hal float
"float-unsigned": ethercat unsigned 32-bit integer to 64-bit hal float
"float-ieee": ethercat floating point 32-bit REAL to 64-bit hal float
"float-double-ieee": ethercat floating point 64-bit LREAL to 64-bit hal float

PDO variable 64 bit

Category: EtherCAT

Ok I will try these commands, but I ask you, if I wanted to read or write in a PDO a float 64 value would it be possible?

This will mean that the pin that will be created will be declared as float 64.

halType="double"?

or hal non support pin declared 64 bit ?

Tommylight,
Thanks for that tweak, I removed those hal calls in the ini file and that error is now gone. I'm now back to my issue of "Can't execute DISPLAY program probe_basic "

Any suggestions?

Attached are my error report and config files

Thanks again for the support and Merry Christmas!

Thank you for fast reply

I try
sudo halcompile --install src/emc/kinematics/trtfuncs.c
I change to dir downloads and change cmd to  : sudo halcompile --install trtfuncs.c
this correct ?
then like halcompile respond but found error about code inside file, or can't use halcompile ?
I see in error red letter on  " ; "  don't know problem from its or not.

thank you,

I would first verify that you have 5V at the 7I77 in case this is an analog
output voltage issue.

Another possibility is encoder count rate issues, especially if there is significant
quadrature distortion. You can try disabling the encoder filter to test this.

You would add that in to an m6 remap, see the probe basic atc sim for an example of remap.

Sure you put everything from post gui hal back in? Look for conflicts. Somewhere you are using program.idle maybe in a pendant, you need to connect both instances so it can be used.

It's your machine 5 axis? You put the geometry in that is in your lower ini.

I connected 5V to the card and the result improved. Unfortunately, there are still problems. Now it is possible to achieve a feed of 15000mm/min in one direction, but only 10500mm/min in the other direction. This happens with all axes. The video shows a program where the table moves in a R150 circle. When moving up to 10000mm/min, the follow error is acceptable, but when moving faster, it starts to accelerate after a certain limit.

I am attaching the .hal and .ini for the X axis.
