Interface hardware
• The interface will use a combination of discrete signals (5 inputs, 3 outputs, and 24 VDC active low) and an
addressable RS422 interface.
• The hardware will provide 4 unique addresses, which allows 4 systems to be connected to one serial port on the
CNC. The addressing mechanism will be inside the power supply, on a PC board (Note: A total of 32 I/O
(20 Inputs, 12 Outputs) points will be required for 4 systems).
• The RS422 hardware will have tri-stateable transmitter to disconnect itself from the line when not
communicating.
• Mounting holes for footprint of CommandTHC plasma interface board.
• Must have an interface compatible with the CommandTHC/HD4070.

Description
Plasma Start
Input
When active, the plasma system will fire an arc.
Machine Motion 1
Output
Indicates the arc has transferred to the plate. This signal is selected
using jumper on power supply control board. Only 1 motion signal
is needed per system. The remaining motion signals can be used to
wire multiple systems in a daisy chain configuration.
Machine Motion 2
Output
Indicates the arc has transferred to the plate. This signal is selected
using jumper on power supply control board. Only 1 motion signal
is needed per system. The remaining motion signals can be used to
wire multiple systems in a daisy chain configuration.
Machine Motion 3
Output
Indicates the arc has transferred to the plate. This signal is selected
using jumper on power supply control board. Only 1 motion signal
is needed per system. The remaining motion signals can be used to
wire multiple systems in a daisy chain configuration.
Machine Motion 4
Output
Indicates the arc has transferred to the plate. This signal is selected
using jumper on power supply control board. Only 1 motion signal
is needed per system. The remaining motion signals can be used to
wire multiple systems in a daisy chain configuration.
Hold Ignition
Input
When active, the system will stay in preflow and delay torch ignition.
The signal should be applied at the same time the start signal is
applied.
System Error
Output
Indicates that an error has occurred in the plasma system. Use the
serial interface to query for the specific error code number.
