Implement IO judgment in NGC files? was created by chen1234
I've been having trouble writing G-code recently and was hoping someone could give me some hints.
I need to implement IO judgment in a .ngc file, such as the function of M66, but it can be implemented directly in G code
test.ngc:Is there a way to program it directly in the NGC file?

if M101 == ture

You can use this in a ngc file
M66 P1 L0
#<ABC> = #5399
o803 IF [#<ABC> EQ 1]
......
o803 ENDIF

thanks,MaHa
I have other little questions
How many pins can M66 define? I see in the documentation that there are 3 each for digital and analog signals, is there any way to expand this number?
Or how to combine this function with PLC?

You can increase the io using the "num_dio" parameter to the "loadrt motmod" command.
Depending on the structure of your HAL / INI files this might need to be done either as a change to the HAL file, or to a parameter read in to the HAL from the INI.

In checked my config, end of this line the amount of analog and digital inputs are set, if you need more than available by default.
I have used this only from hal
loadrt [EMCMOT]EMCMOT servo_period_nsec=[EMCMOT]SERVO_PERIOD num_joints=[KINS]JOINTS num_aio=16 num_dio=8I have used this only from hal
net cb11 pyvcp.checkbutton11 motion.digital-in-01

Thanks ，andy, MaHa
I will try to expand the number of IOs.
I have a new question, I want to add PLC function, how can this PLC be used with M66?

A real PLC or a soft PLC (ie, ClassicLadder)?
I think that you would connect the PLC inputs and outputs to the same motion pins that you are already using, in the HAL layer.
