Termination
Termination of the fieldbus requires a terminating resistor at each end of the
fieldbus. These resistors should have a value of 121 ohms.
EDS File
Each device on a DeviceNet network is associated with an EDS file containing
all necessary information about the device to be connected. The network
configuration program uses this file during configuration of the network.
The EDS file associated with the FEC device can be downloaded from the
FEC website. www.fec-usa.com (file: abs.eds)
Direct link:www.fec-usa.com/fecusacomnew/support/index.htm
(the file can also be downloaded directly from HMS - www.hms.se)
Note: The FEC system will appear in the network Vendor list as “HMS
Fieldbus Systems” and in the network as “Anybus-S Devicenet” adapter. This
is the manufacturer of the interface board which is integrated into the Multi
Unit.

Interface Board Specifications
* Typical configuration is 32 Bytes (256 I/O points) but can be altered using
the AFC Software package. (See AnyBus-S Reference at the end of this
chapter for I/O Setting example.)
See section 4 (I/O signals) for reference of typical fieldbus I/O layout.
Operation Note: The first 16 bits of I/O are used by Devicenet
communication. The first input must be set “ON” to enable communication.
