Module Definition Dialog Box

The Module Definition dialog box contains a set of configuration parameters

that affects data transmission between the controller and the I/O module.

The Change button on the Module Properties General tab provides access where

the listed parameters can be changed.

This is where you specify the Series, Revision, and Electronic Keying. You can do

the following:

• Choose connection type

• Select alternating or simultaneous mode

• Assign the data format type

TIP

Online edits are not possible when the controller is in RUN mode. Online edits

must be made only when the controller is in Remote Run or Program modes.

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

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.
