Parameter Description
Series Module’s hardware series.
Revision Major and minor firmware revision levels used on the module.
Electronic Keying When you configure a module, you specify the slot number for the module. However, it is
possible to purposely or accidentally place a different module in that slot. Electronic keying lets
you protect your system against the accidental placement of the wrong module in a slot. The
chosen keying option determines how closely any module in a slot must match the
configuration for that slot before the controller opens a connection to the module. There are
different keying options depending on your application needs. See
Using Electronic Keying on
page 105 for detailed information.
Connection The connection type between the controller writing the configuration and the I/O module is
Output.
Data Format Integer data transferred between the controller and I/O module and what tags are generated
when the configuration is complete.
