Configuration
FEC Profibus I/O configuration is programmable using the AFC User Console software. I/O can be
set as required by the application according to parameter limits set forth by the GSD (Profibus)
configuration file. The AFC Software allows configuration of the number of I/O in the Multi Unit.
Configuration of the Profibus Master MUST match the configuration of the FEC Profibus slave. In
the Profibus Master setup, input size and output size is set as “byte” ordering. (Do not use “word”
ordering. This will inverse the I/O location) When setting the Profibus Master configuration, PLC
input size refers to FEC output size (ie. Accept, Reject, Busy, etc.) and PLC output size refers to
FEC inputs (ie. Start, Stop, Reset, etc.). FEC will show up as 2 modules. Module 1 is inputs, module
2 is outputs. (See AnyBus-S Reference at the end of this chapter for I/O Setting example.)
GSD File
Each device on a Profibus network is associated with a GSD file containing all necessary
information about the device to be connected. The network configuration program uses this file
during configuration of the network.
The GSD file associated with the FEC device can be downloaded from the FEC website. www.fec-
