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).

5.1 How

Master/Slave

Communication Takes Place

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. If you are using the Rockwell Automation 1785-PFB/B coprocessor
as a master, you must use the Rockwell Automation PROFIBUS Manager
Software configuration tool. Since the FLEX I/O adapter is compatible with any
master, you can use any configuration tool available on the market.

The device database (GSD) file is included on the software diskette you
received with your shipment of the FLEX I/O adapter. The PSFT0882.GSD file is
used by your configuration tool to help you set up your system. Your
configuration tool automatically reads the PSFT0882.GSD file and extracts
defaults used in the data exchange.

The file is in ASCII format and you can view it with any text editor. A printed copy
of your PSFT0882.GSD file appears in the Reference chapter.
