Modbus TCP issue with pokeys57E

Hi
I have been trying to set up modbus TCP with pokeys57E on linuxcnc 2.8 RT on debian stretch. For some reason I get error which has caused me to pull out my hair:silly: I took an error report from the whole modbus listing in case if someone knows what could be going on. The file happens to be 1.7mb so it won't fit here as attachment so I had to compress it.

I also attached my modbus.ini file so if anyone kind enough can take a look and hint me what I have set wrong or if pokey57e has some issue with modbus let me know.

Thank you in advance

is your error which is in your nyx.hal file @ or around line 125. After you clear this error you may have others pop up, so it's just a case of either closely reviewing your hal files or fixing one error at a time.

You've got:

[modbus.xplus.num_errors]
[modbus.xplus.00]

created already.

Your error is:

"./nyx.hal:125: Pin 'modbus.xplus' does not exist"

Do you want to (or can you?) create a pin that is the root of existing ones?

Otherwise, I'm very familiar with this particular error message. Not all that proficient in fixing them yet however...

Can you post your nyx.hal file?

Ok got forward on this, I had to change "modbus.xplus" to "modbus.xplus.00" and it seems to not complain anymore modbus pins, now however it complains the pin which it is attached in hal "halui.jog.0.plus"

"net jog_x_plus <= modbus.xplus.00 => halui.jog.0.plus

dunno why it can't find the halui pin as I have also halui set in ini file

Can you post your INI and HAL files?

Sorry, I found reason for this... I used hal documentation 2.8 : linuxcnc.org/docs/2.8/html/config/core-components.html

and when I tried instead commands from devel:
linuxcnc.org/docs/devel/html/man/man1/halui.1.html

it works. Dunno how it is possible as I have 2.8. It seems the documentation is not that great on linuxcnc at some parts. I used now "halui.axis.x.plus" and it was accepted

Indeed, there is still a reference in the 2.8 docs to halui.jog:

linuxcnc.org/docs/2.8/pdf/LinuxCNC_Documentation.pdf



despite the fact that the halui.jog have been replaced in 2.8:

linuxcnc.org/docs/2.8/html/getting-start...dating-linuxcnc.html




Could somebody fix that?

Did you read the 2.8 docs ?
linuxcnc.org/docs/2.8/html/man/man1/halui.1.html

linuxcnc.org/docs/2.8/html/gui/halui.html

@Beagle

It's fine there
linuxcnc.org/docs/2.8/html/man/man1/halui.1.html

but it's wrong here

linuxcnc.org/docs/2.8/pdf/LinuxCNC_Documentation.pdf

and here:

linuxcnc.org/docs/2.8/html/gui/halui.html

also here (as I presume this is the doc meant for the current stable release):

linuxcnc.org/docs/html/gui/halui.html

Another I'd like to add, and this is a situation that has manifested itself a bit lately, is that we've had users having errors and contributing the errors to a part of Linuxcnc. Now if these user had of read the error file, which gives a very clear reason to what the error is, a lot of time could have been saved.
What has frustrated me more, to a point where I gave up offering help, is that some users wont even bother to look or start multiple threads. Even after they have had be shown how to find the error.

Ok rant over....and yes I understand the OP is new.

Ok now would it be easier if the Debug stanza was at the top of the error report ?
