Digital Module Operation in a Control System Chapter 1
Output Mode Available with Compact 5000 I/O Safety Input Module
The Module Definition for the 5069-OBV8S or 5069-OBV8SK safety output
module includes the Output Mode parameter. This parameter defines whether
the module is operating in Sourcing or Bipolar mode.
For more information on the Module Definition parameters that are available
with Compact 5000 I/O digital 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 following are valid RPI
values:
• Compact 5000 I/O standard modules - 0.2…750 ms
• Compact 5000 I/O safety modules - 2…500 ms
Connection Reaction Time Limit with Compact 5000 I/O Safety Modules
With Compact 5000 I/O safety modules, the Connection Reaction Time
Limit configuration affects the module RPI.
The Connection Reaction Time Limit defines the predicted period of safety
packets on the associated connection. If the Max Network Delay exceeds the
Connection Reaction Time Limit, a connection fault occurs.
IMPORTANT If the Configured By parameter is External Means, the Output Mode
parameter is disabled. It is automatically set to None.
IMPORTANT You can change the RPI while the project is online. If you change the RPI
while the project is online, however, the connection to the module is closed
and reopened 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
reopened immediately after you apply the change to the module
configuration.
