FEC AFC1500 - Manual (Page 36)

DeviceNet Interface board
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
hardwiring/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. Its maximum communication baud rate is
500K baud with a maximum cable distance of 100 m., 250 K baud at a 250m
max. cable length or 125K baud with a maximum cable distance of 500m.
Node addressing (MAC ID) & baud rate is selectable using the baud/address
selection DIP switch. Module & Network status LED’s provide network
diagnostics. 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 AFC 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

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