Hello,

I'm still new to the RX3i Processor and I'm struggling a bit.
I have to control an Altivar71 VFD Via Modbus TCP.
The RX3i processor (IC695CPE305) is paired with an ETM001 Module.
The VFD has a Modbus TCP Daisy Chain Ethernet Card (VW3A3310).
I have exchanged data with the drive using the COMMREQ instruction by accessing specific addresses in the drive, but this is proving difficult.
I was hoping that there was a better way to do this.
Fortunately I have everything I need setup to test with complete with Motor.


Thanks,
jloy
