Hi, brothers
I have a Linux CNC program. The ". Ini" file and ". Hal" file have been configured.
Now I want to write a python API to talk to Linux CNC. Get the status of Linux CNC through Python API

I found the instructions on the official website:
linuxcnc.org/docs/stable/html/config/pyt....html#python:reading -ini-values”

I wrote the python API file according to the instructions and loaded it into the ". Hal" file.
I run linuxcnc and find that all the printed ones are 0. Why?
I only get three basic attributes in the python API, which are:
joints  ,   task_ state   ,    cycle_ time
These three values can't be 0. Is there something wrong with my program?

I'll put my Python API, the ". Hal" file and the basic attribute pictures I use below

Thank you

You need

s.poll()

In your loop to update the values.

(it needs to be in the loop, to run every cycle and update the values)
