Appendix F Status Indicators
Controller Status Indicator and Display
Indicator Status Description
RUN Off The controller is in Program or Test mode.
Solid green The controller is in Run mode.
I/O Off Either:
• There are no devices in the I/O configuration of the controller.
• The controller does not contain a project (controller memory is empty).
Solid green The controller is communicating with all the devices in its I/O configuration.
Flashing green One or more devices in the I/O configuration of the controller are not responding.
Flashing red A virtual chassis error was detected. Contact your Rockwell Automation representative or local distributor.
FRC Off No tags contain I/O force values.
I/O forces are inactive (disabled).
Flashing green At least one tag contains an I/O force value.
I/O force values are inactive (disabled).
Solid green I/O forces are active (enabled).
I/O force values may or may not exist.
RS232
(1)
Off No COM port was selected.
Solid green The selected COM port was successfully assigned to channel 0 of the controller.
Solid red There is a COM port conflict or you selected an invalid COM port number.
BAT
(1)
Off Normal operation.
Flashing amber The controller is in Power-up mode.
Solid red Persistent storage for the controller has failed.
OK Flashing red If the controller is a new controller, then the controller requires a firmware update.
And the controller is not a new controller, then a major fault occurred.
To clear the fault, either:
• Turn the keyswitch from PROG to RUN to PROG
• Go online with RSLogix 5000 software
Solid red The controller detected a non-recoverable fault, so it cleared the project from memory.
To recover, follow these steps.
1. Cycle power to the chassis.
2. Download the project.
3. Change to Run mode.
If the OK status indicator remains solid red, contact your Rockwell Automation representative or local distributor.
Solid green The controller is OK.
(1) Note that these status indicators function slightly different than the same status indicators on a ControlLogix controller.
