Chapter 7 Common Features of the 1732E-IB8M8SOER and 1732E-OB8M8SR Modules

The table describes the communication formats used with input modules.

Electronic Keying

Electronic keying allows the ControlLogix system to control what modules

belong in the configured system.

During module configuration, you must choose one of the following keying

options for your module:

• Exact Match

• Compatible Module

• Disable Keying

When the controller attempts to connect to and configure a module (for

example, after program download), the module compares the following

parameters before allowing the connection and configuration to be accepted:

• Ve n d o r

• Product Type

• Product Code

• Major Revision – Change that affects the module function or

RSLogix 5000 interface

• Minor Revision – Change that does not affect the module’s intended

function or RSLogix 5000 interface

The comparison is made between the keying information present in the module

and the keying information in the controller program, preventing the inadvertent

operation of a system with the wrong module. For example, if you select Exact

Match and a module with revision 1.2 is placed in a location configured for a

module with revision 1.4, the controller does not make a connection to the new

module because of the mismatched revisions.

Data Return Communication Format Module

Module returns input data with

the value of the system clock

(from its local chassis) when the

input data changes.

CIPSync/PTP time input data 1732E-IB8M8SOER

The owner-controller sends the

module output data and a CIPSync

(PTP) time value
