Analog I/O Module Operation in a Logix5000 Control System Chapter 1
Data Types Available with 5069 Compact I/O Analog I/O Modules
The Module Definition includes a Data parameter that matches the module type.
Analog input modules use Input Data, and analog output modules use Output
Data.
The available Data parameter choices are as follows:
• Analog input modules - The Input Data choice is always Analog Data.
• Analog output modules - The Output Data choices are Analog Data or
None. The Output Data choice None is only available if you choose the
Connection parameter Listen Only.
Requested Packet Interval
The Requested Packet Interval (RPI) is a configurable parameter that defines a
specific rate at which data is exchanged between the owner-controller and the
module.
You set the RPI value during initial module configuration and can adjust it as
necessary after module operation has begun. Valid RPI values are 0.2…750 ms.
To see where to set the RPI, see
page 90.
For more information on guidelines for specifying RPI rates, see the Logix5000
Controllers Design Considerations Reference Manual, publication
1756-RM094.
IMPORTANT
If you change the RPI while the project is online, the connection to the module
is closed and re-opened in one of the following ways:
• You inhibit the connection to the module, change the RPI value, and
uninhibit the connection.
• You change the RPI value. In this case, the connection is closed and re-
opened immediately after you apply the change to the module
configuration.
