Data Types Available with FLEX 5000 Standard I/O Modules
The Module Definition includes a Data parameter that matches the module type.
Digital input modules use Input Data, and digital output modules use Output
Data.
The module type and Connection choice determine the available Input Data or
Output Data choices. For example, you can configure a 5094-IB16 digital input
module to use the Connection choice Data with Events. The resulting Input Data
choices are Data with Events include Data, Packed Data, or Timestamped Data.
For more information on the Connection and Data parameter choices available
with FLEX 5000 I/O modules, see the Logix Designer application.
IMPORTANT This section shows some Logix Designer application screens that are used
when you configure FLEX 5000 I/O safety modules. For a complete
description of how to configure the modules, see
Replace Safety Modules on page
During module configuration, you must define the module. Among the Module
Definition parameters with FLEX 5000 safety I/O modules, you must choose
how module is configured.
The choice depends on whether the project is downloaded to the controller that
owns the module configuration
that is listening to input modules in a project.
A real-time data transfer link is established between the controller and the
module that occupies the slot that the configuration references.
When you download module configuration to a controller, the controller
attempts to establish a connection to each module in the configuration.
Because part of module configuration includes a slot number in the remote
FLEX 5000 I/O system, the owner-controller checks for the presence of a
module there. If a module is detected, the owner-controller sends the
configuration. One of the following occurs:
• If the configuration is appropriate to the module detected, a connection is
made and operation begins.
• If the configuration is not appropriate to the module detected, the data is
rejected and the Logix Designer application indicates that an error
occurred.
The configuration can be inappropriate for many reasons. For example,
a mismatch in electronic keying that helps prevents normal operation.
