This example shows some basic data exchanges between a Parker AC30 VFD drive and a Parker Interact Xpress XT HMI over a Modbus/TCP connection.
See the DSELite help document for the ETH block for Modbus/TCP implementation details.
The specific Modbus/TCP settings in the Xpress application are as follows to match up the AC30 DSE Firmware defaults pretty closely.
The AC30 Modbus implementation limits 'block reads' to 120 registers or less.
