Entering check configuration data 4-8
Read configuration response data 4-10
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 (GSD) file is included on the software diskette
you received with your shipment of the FLEX I/O adapter. The GSD
file 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.
The file is in ASCII format and you can view it with any text editor.
A printed copy of your GSD file appears in Appendix B of this user
manual.
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.
