7 RS-485 Communication Features
This section in the user manual explains how to control the inverter with a PLC or a
computer over a long distance using the RS-485 communication features. To use the RS-
485 communication features, connect the communication cables and set the
communication parameters on the inverter. Refer to the communication protocols and
parameters to configure and use the RS-485 communication features.
7.1 Communication Standards
Following the RS-485 communication standards, H100 products exchange data with a PLC
and computer. The RS-485 communication standards support the Multi-drop Link System
and offer an interface that is strongly resistant to noise. Please refer to the following table for
details about the communication standards.
