4.15.3 Fieldbus Interfaces – DeviceNet ®
DeviceNet ® Interface
The DeviceNet communication interface allows slave connection to an industrial DeviceNet net-
work. DeviceNet allows industrial devices to be controlled over an open network architecture
enabling device connection at various locations in the field. This “fieldbus” technology reduces
hard wiring/cabling & provides ease of installation. It uses a broadcast-oriented protocol -the CAN
(Controller Area Network)- that can interface to many devices such as limit switches, sensors, di-
rectional valves, motor starters, bar code readers, process sensors, frequency drives, etc. The
network can have up to 64 nodes.
Maximum I/O data is 512 input bytes & 512 output bytes. FEC Inputs/Outputs are shown in the
following I/O signal map layout.
Note: The DeviceNet interface is implemented according to the ODVA specification for a commu-
nications adapter (profile no.12). It is acting as a “group two only server” on the DeviceNet net-
work.
FEC integrates the DeviceNet board manufactured by HMS Fieldbus Systems AB into the Multi-
Unit modular I/O board. For further technical information on the DeviceNet interface go to the
HMS website. ( www.hms.se )
Further DeviceNet information can be found through the Open DeviceNet Vendors Association
(ODVA). ( www.ODVA.org )
