Connect for Communication
- Communication methods for XPR® cutting systems
  There are multiple communication methods to fully operate the plasma cutting system.
- Requirements for EtherCAT®
  This information prepares you to connect the plasma power supply to the Computer Numerical Control (CNC) with EtherCAT® cables.
  - Connect to the plasma power supply with EtherCAT®
- Requirements for serial RS-422
  This information prepares you to connect the plasma power supply to the Computer Numerical Control (CNC) with serial RS-422 cables.
- Requirements for discrete
  This information prepares you to connect the plasma power supply to the Computer Numerical Control (CNC) with discrete cables.
- Requirements for the XPR® web interface
  You can connect to the XPR® web interface through Wi-Fi® with Access Point (AP) mode or with network mode.
- Change the device that has control
  Use these steps to make sure that the correct device has control of the plasma power supply.
- Use ohmic contact sense
  You can use internal or external ohmic contact sense. No action is necessary for internal ohmic contact sense. To use external ohmic contact sense, make the following modification to the ohmic wiring inside of the TorchConnect™ console.
- Install a remote on-off switch
  As an alternative to using the main power supply, do these steps to install your own remote on-off switch so that you can control power to the gas connect console, TorchConnect™ console, and other parts.
- Install a redundant remote on-off switch
  Do these steps if you want to use the redundant remote on-off switch.

Requirements for EtherCAT

This information prepares you to connect the plasma power supply to the Computer Numerical Control (CNC) with EtherCAT® cables.

For an example of a system diagram, refer to multi-drop (multi-system) interface (Sheet 19 of 25).
For information about signals and protocols, refer to EtherCAT communications and Serial RS-422 and EtherCAT commands in the CNC Communication Protocol for the XPR Cutting System (809810).
Hypertherm® sells EtherCAT cables that have been tested with our cutting system. Refer to CNC interface cables.
If you supply your own cables, choose EtherCAT cables that follow the Beckhoff® specification. Refer to cable specifications.
To help prevent problems from Electromagnetic Interference (EMI), make sure that the EtherCAT cables:
- Have separation from the pilot arc cable, negative cable, or any power cables that have a voltage more than 120 VAC. Refer to Distance requirements between high-frequency cables and control cables.
- Are not near the gas connect console or TorchConnect™ console.
Hypertherm recommends a minimum distance of 1 meter (3.3 feet) between the plasma power supply and other system components, or between the plasma power supply and an obstacle.
