Special I/O and Flexible Format Settings

Special I/O and Flexible Format that utilize the Modbus communication method enable you to control
various inverter functions and parameters through the Remote I/O function.
This section describes how to configure these types of Remote I/O.
Inverter parameters can be configured using the Digital Operator, CX-Drive, or CX-Integrator.
CompoNet Node Address Setting
