Serial Communication Programmer Reference Guide
Powermax65/85/105 SYNC Reference Guide 810400 7
Getting started
The Powermax65/85/105 SYNC plasma power supply supports serial communication with an
external control using the Modbus serial communication protocol.
This guide is for the programmer who will use Modbus protocols and messages for communication
between the Powermax65/85/105 SYNC and an external control such as a CNC or torch height
control (THC). It lists the supported Modbus function codes and the Powermax65/85/105 SYNC
register and coil addresses with which those function codes can be used. It also describes how to
construct the messages for the Powermax65/85/105 SYNC.
For more information about the Modbus protocol, refer to modbus.org
