Digital Module Operation in a Control System Chapter 1
Because part of module configuration includes a slot number in the local or
remote 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 prevent normal operation.
The owner-controller monitors its connection with a module. Any break in the
connection, for example, the loss of power to the system, causes a fault. The
Logix Designer application monitors the fault status tags to indicate when a
fault occurs on a module.
Connection Types Available with Compact 5000 I/O Standard Modules
The Connection choice determines what data is exchanged between the
owner-controller and the module. The following are example Module
Definition dialog boxes, and available Connection choices, for Compact 5000
I/O standard modules.
