AC10 Modbus-RTU Example to Interact with Xpress HMI (XTA)

This example shows some basic data exchanges between a Parker AC10 VFD drive and a Parker Interact Xpress XT HMI over Modbus/RTU and an RS485 connection.

See the AC10 Installation Guide for more details on its Modbus/RTU implementation (Chapter 12):

AC10 IP20 User Guide

AC10 IP66 User Guide

The specific Modbus/RTU settings in the Xpress application are as follows to match up the AC10 defaults pretty closely.

The AC10 Modbus implementation limits 'block reads' to 10 registers or less.
