Configure the Adapter for Master/Slave
Communication
Overview Read this chapter to familiarize yourself with input, output and configuration
files for analog I/O modules on the PROFIBUS network.
How Master/Slave
Communication Takes
Place A data exchange between the master and slave cannot be performed until check
configuration and send parameter data are issued. Each time you power-up the
network, the master sends check configuration and send parameter data to the
slave (FLEX I/O adapter).
Check configuration data determines or checks the number of input and output
words used by each FLEX I/O module.
Send parameter data contains device-specific parameters you define for each
FLEX I/O module.
You need a software configuration tool to set the values associated with these
parameters. Since the FLEX I/O adapter is compatible with any master, you can
use any compatible configuration tool available.
The Device Database File (GSD) is used by your configuration tool to help you
set up your system. Your configuration tool automatically reads the GSD file and
extracts defaults used in the data exchange. For more information on GSD files,
see Appendix B on page 105.
The file is in ASCII format and you can view it with any text editor. To download
a printable copy of your GSD file, see Appendix B on page 105.
The user parameter data fields are not defined in the GSD file. Depending on the
format you choose, you may have to manually edit these values with your
configuration tool.
For more information on how you define and enter these user parameter values,
refer to the documentation associated with your master and software
configuration tool.
