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:
• Vendor
• 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
