Plasma component in Gmoccapy

Plasma component in Gmoccapy was created by rodw
Guys,

I'm using a mesa 7i76e and a THCAD-10 card
I just moved my config from axis GUI to gmoccapy which was surprisingly painless :)

Well that is until I tried to connect my THC pins to gmoccapy
The plasma sim has this line
Code:
net curvolt plasma.Target-Voltage => plasma.hal-lbl-cur-volt

so I assumed all I needed to do was change it to
Code:
net curvolt thc.volts => plasma.hal_lbl_cur_volt

The system then complains that plasma.hal_lbl_cur_volt does not exist. The plasma component is loaded when i Look in halshow so I'm not really sure what I've done wrong. Any help would be appreciated.

Hallo rodw,

I am pretty sure, that you do load the mentioned line in a normal hal file.
As the plasma stuff are just different embedded tabs, you have to put that line in hal file, that is loaded with the embedded tab.

The tab is loaded as follows:
Code:
EMBED_TAB_NAME = coolant_spindle_panel EMBED_TAB_LOCATION = box_coolant_and_spindle EMBED_TAB_COMMAND = gladevcp -x {XID} -u plasma.py -H plasma.hal plasma.glade

In your case the mentioned line need to be in the plasma.hal file.

The reason is, that the embedded tabs are loaded after the GUI is displayed, so the hal pin are not available at earlier time, that after loading the embedded tab.

You have used different names for the pins. Underscores are not the same as dashes. I do this all the time because I type so poorly.

Sorry

I will post my working HAL lines for the THCad when I get to my linux machine.

Here are excepts from my HAL files. The arc voltage display and settings are working as far as I can tell from connecting an external voltage source to the THCad input.
From main HAL file:
Code:
#******************* # THC stuff #******************* # save for future THC with PID setp pid.thc.Pgain 10 setp pid.thc.Igain 1 setp pid.thc.bias 0 setp pid.thc.Dgain 0 setp pid.thc.FF0 0 setp pid.thc.FF1 0 setp pid.thc.FF2 0 setp pid.thc.deadband 1 setp pid.thc.maxoutput 100 #setp pid.thc.error-previous-target true #net thc-index-enable <=> pid.thc.index-enable #net thc-enable => pid.thc.enable #net thc-vel-cmd-rpm => pid.thc.command #net thc-vel-fb-rpm => pid.thc.feedback net scaled_arcvolts scale.arcvolts.out => pid.thc.feedback #net thc-output <= pid.thc.output # ---Encoder Setup for THC-- setp hm2_7i76e.0.encoder.00.counter-mode 1 setp hm2_7i76e.0.encoder.00.filter 0 setp hm2_7i76e.0.encoder.00.scale -1 net thc-vel-in hm2_7i76e.0.encoder.00.velocity => thc.encoder-vel # Value for my THCad card setp thc.scale-offset 124400 #Value for my THCad card and voltage divider (18.94181:1) setp thc.vel-scale .0002238191 #this may need changing setp thc.correction-vel .0001 #this starts arc net Torch_On and2.torch-enable.out #starts motion on arc transfer to work this will need to change for my setup net arcok thc.arc-ok motion.digital-in-00 #********************************* # experimental use of components for testing future THC enhancements #******************************** #these settings are scaling encoder counts to arcvolts using scale component #Value for my THCad card and voltage divider (18.94181:1) setp scale.arcvolts.gain .0002238191 # Value for my THCad card 124400 * .0002238191*-1 setp scale.arcvolts.offset -27.843 net thc-vel-in scale.arcvolts.in #these settings are to get the arc voltage rate of change net scaled_arcvolts ddt.arcvolts_rate.in

This is from one of my auxilary HAL files:
Code:
#link arc voltage to both tabs net curvolt_tab thc.volts => plasma_tab.hal-lbl-cur-volt-tab net scaled_arcvolts plasma.hal-lbl-cur-volt #link target voltage values between tabs net target_volts_tab plasma_tab.Target-Voltage => plasma.hal_lbl_target_voltage_main

I have two sources of arc volts shown because I was testing the scale component for for scaling the TCHad output. Note that I have two places on my screen that display the arc volts. One is on a tab in the main screen and one is on a tab with other tabs in the preview location.

Norbert, thanks, I think this is my problem. I copied my .hal and .ini files over from another config into a fresh plasma sim config and went to town on them. My Ini file is still pointing at plasma.hal, not the .ini file I am editing. Thanks a lot!

John, the typo is just confined to the forum post above. I had it right in my hal file. Thanks for posting your config. I will review it. We are both on the same journey just mine is slower as I have to build everything, not just retrofit an existing table...
I've got all the THC signals tested and working except for the interface to the GUI which I'm just starting on. Once I get that done, I want to try a few things in the THC component.
