Data transmission
The module only supports cyclic I/O data transmission.
Configuration
FEC Profibus I/O configuration is programmable using the DSP 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 DSP 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.
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.
