10.16.2 easyE4 Communication via Modbus RTU
The EASY-COM-RTU-… communication module allows the control relays in the
easyE series to establish a communication connection via Modbus RTU. This not only
makes it possible to use Modbus-RTU-capable Eaton devices, but also Modbus-RTU-
capable devices from third parties.
The Modbus RTU communication module can be configured as a master or as a
slave.
If the EASY-COM-RTU-… is used as a master, the easyE4 base device will control all
data traffic on the bus by sending requests to the relevant slaves in the Modbus RTU
communication system.
If the EASY-COM-RTU-… is used as a slave, the easyE4 base device will respond to
requests from the Modbus RTU master.
Among other things, this means that Modbus RTU communications are also possible
between multiple easyE4 base devices.

set up as Modbus RTU slaves (DE1, DC1, DG1, DA1, easyE4, and others)
