The ECO fieldbus coupler is designed for applications with a reduced scale I/
O requirement. Using digital only process data or small amounts of analogs,
while retaining all of the choice that’s 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
TM
buscoupler automatically configures, creating a local process
image which may include analog, digital or specialty modules.
DeviceNet
TM
stores the process image in the corresponding Master 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 Device-
Net
TM
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
buscoupler automatically starts with a new byte.
