3.1.1 Description

The ECO fieldbus coupler is designed for applications with a reduced scale
I/O requirement. By using digital only process data, or small amounts of ana-
log data, the ECO Fieldbus coupler retains all of the choices that are offered
by the Series 750 I/O.
The coupler has an integrated supply terminal for the system voltage. The field
power jumper contacts are supplied via a separate supply module.
The DeviceNet bus coupler is capable of supporting all I/O modules and au-
tomatically configures, creating a local process image.
DeviceNet allows the storing of the process image in the corresponding Mas-
ter control (PLC, PC or NC).
The local process image is divided into two data zones containing the data re-
ceived and the data to be sent.
The process data can be sent via the DeviceNet fieldbus to the PLC, PC or NC
for further processing, and received from the field via DeviceNet TM.
The data of the analog modules is stored in the process image which is created
automatically according to the order in which the modules are connected to the
buscoupler. The bits of the digital modules are sent byte by byte and added to
the analog data. If the amount of digital information exceeds 8 bits, the bus-
coupler automatically starts with a new byte.
