Product Overview
Description
Eaton Electrical Intelligent Technologies (
IT
) D77 Modbus Adapter (D77D-EMA) has
greatly increased the functionality of the
IT
communicating products, allowing monitoring
and control for
IT
IO and
IT
motor control devices. The Adapter subscans the devices
and then concentrates all their data into a single Modbus node.
To simplify the configuration of the Modbus Adapter, a simple button press will auto
configure the system for default operation. This feature automatically configures the IO
data into registers in a convenient scan table.
