CNC controller requirements
Note:    See appendix B, CNC interface protocol, for more detailed information.
Base required elements
The following elements should be able to be displayed and adjusted on the CNC for setup and basic system 
information. The plasma system needs this group for basic setup and operation capability.
 1.  Remote ON/OFF
  2.   Ability to display and adjust the basic plasma process set-points (command ID No. 95)
a.   Current set point
b.   Plasma  preflow
c.   Plasma  cutflow
d.   Shield  preflow
e.   Shield  cutflow
f.   Plasma gas type
g.   Shield gas type
h.   Gas mixing set-points
  3.   Display basic system information
a.   System error code
b.   Gas and PS firmware version
  4.   Manual pump control
Required real time elements
The following elements should be able to be displayed in real time while cutting. This is necessary for trouble shooting 
and diagnostic purposes.
  5.  Display line voltage
  6.  Display chopper current
  7.  Display work lead current
  8.  Display system status code
  9.  Display chopper temperature
10.  Display transformer temperature
11.  Display coolant temperature
12.  Display coolant flow
13.  Display pressure transducers
Required diagnostic elements
These elements provide additional diagnostic capability to the system for troubleshooting gas-delivery problems. The 
CNC should be capable of executing these commands and displaying the relevant information for the respective test 
according to the serial protocol guidelines.
14.  Test preflow gases
15.  Test cutflow gases
16.  Inlet leak test
17.  System leak test
18.  System flow test
