Interface
The DeviceNet communication interface allows slave connection to an industrial DeviceNet network.
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,
directional 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 match the discrete input
layout. FEC Output location is programmed using the DSP User Console Software.
Note: The DeviceNet interface is implemented according to the ODVA specification for a
communications adapter (profile no.12). It is acting as a “group two only server” on the DeviceNet
network.
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. (

Further DeviceNet information can be found through the Open DeviceNet Vendors Association
(ODVA). (
