Module Status (MS) Indicator

The Module Status (MS) indicator is located
under the space provided for you to write the IP
address of the packaged controller and is one of
the Ethernet/IP network status indicators.
Description
Either one of the following:
• There are no devices in the I/O configuration of the packaged controller.
• The packaged controller does not contain a project.
The packaged controller is communicating with all the devices in its I/O configuration.
One or more devices in the I/O configuration of the packaged controller are not
responding.
Either one of the following:
• The packaged controller is not communicating with any devices.
• The packaged controller is faulted.
No power is applied.
One of the following conditions exists:
• The packaged controller requires a firmware update.
• A major recoverable fault occurred on the packaged controller. To clear the fault,
perform this procedure.
• Turn the packaged controller keyswitch from PROG to RUN to PROG.
• Go online with RSLogix 5000 software.
• A nonrecoverable major fault occurred on the packaged controller. In this case, the
packaged controller:
a. OK indicator initially displays steady red.
b. Resets, clearing the project from memory.
c. Sets the OK indicator to flashing red.
d. Produces a major recoverable fault.
e. Generates a fault code in the RSLogix 5000 project.
The fault code displayed in RSLogix 5000 software and the subsequent fault recovery
method depends upon your system.
Upon power-up, the OK indicator is steadily red for a few moments. This is normal
behavior and is not a fault.
If the OK indicator is steadily red for more than a few moments or changes to steadily
red while in use, then a nonrecoverable major fault has occurred and project memory
has been cleared.
To recover from a major fault, cycle power to the packaged controller, re-download
the project, and put the packaged controller in Run mode.
If the OK indicator remains steadily red, contact your Rockwell Automation
representative or local distributor.
Packaged controller is OK.
The packaged controller is storing or loading a project to or from nonvolatile memory.
