Connection Tab
The Connection tab on the Module Properties dialog box lets you enter a
requested packet interval (RPI), inhibit a module, and set a connection fault
Module Definition Fields
Field Name Description
Series Specifies the module series.
Revision Specifies the module’s major and minor revision.
Electronic Keying The electronic keying feature automatically compares the expected
module, as shown in the RSLogix 5000 I/O Configuration tree, to the
physical module before I/O communication begins. You can use electronic
keying to help prevent communication to a module that does not match
the type and revision expected.
For each module in the I/O Configuration tree, the user-selected keying
option determines if, and how, an electronic keying check is performed.
Typically, three keying options are available:
• Exact Match
• Compatible Module (default value)
• Disable Keying
Exact Match is an electronic keying protection mode that requires the
physical module and the module configured in the software to match
according to vendor, catalog number, major revision and minor revision.
Compatible Module indicates that the module determines whether to
accept or reject communication. Compatible Keying is the default setting.
It allows the physical module to accept the key of the module configured
in the software, provided that the configured module is one the physical
module is capable of emulating. The exact level of emulation required is
product and revision specific.
Disable Keying indicates the keying attributes are not considered when
attempting to communicate with a module. Other attributes, such as data
size and format, are considered and must be acceptable before I/O
communication is established. With Disabled Keying, I/O communication
may occur with a module other than the type specified in the I/O
configuration tree with unpredictable results. We generally do not
recommend using Disabled Keying.
Connection Available options are Data, Input Only, Exclusive Owner, and Listen Only.
Calibration and Configuration options are not available for Listen Only
option.
Input Only specifies an independent connection where a device receives
inputs from the target device and sends configuration data to the target
device. An Input Only connection does not send outputs; it only receives
inputs. You can specify multiple Input Only connections to the target
device from different originators.
Exclusive Owner specifies an independent connection where a single
device controls the output states in the target device. If you have an
existing Exclusive Owner connection to a target device, you cannot
specify another Exclusive Owner or Redundant connection to that same
target device.
Listen Only specifies a dependent connection where a device receives
inputs from the target device, but does not send configuration data with
the target device. A Listen Only connection only functions properly when
another non-Listen Only connection exists to the same target device. A
Listen Only connection does not send outputs; it only receives inputs. You
can specify multiple Listen Only connections to the target device from
different originators.
