Chapter 1 Digital I/O Module Operation in a Logix 5000 Control System
Data Types Available with FLEX 5000 Safety I/O Modules
The Module Definition includes a Data parameter that matches the module type.
Safety input modules use Input Data, and safety output modules use Output
Data.
The module type and Connection choice determine the available Input Data or
Output Data choices. We recommend that you use Safety Data as the Input Data
choice unless you need to use Safety Packed Data for backward application
compatibility.
For more information on the Connection and Data parameter choices available
with FLEX 5000 I/O modules, see the Logix Designer application.
Requested Packet Interval
The requested packet interval (RPI) is a configurable parameter that defines a
rate at which the owner-controller and the module exchange data. You set the
RPI value during initial module configuration and can adjust it as necessary after
module operation has begun.
The valid RPI values for FLEX 5000 I/O safety modules are 2…500 ms.
