Flashing green One or more devices in the I/O configuration of the controller are not responding. Go online with RSLogix 5000 software and check the I/O configuration of the controller.
Flashing red The chassis is bad. Replace the chassis.
FORCE Off • No tags contain I/O force values.
• I/O forces are inactive (disabled).
Solid amber • I/O forces are active (enabled).
• I/O force values may or may not exist.
• Use caution if you install (add) a force. If you install (add) a force, it immediately takes effect.
Flashing amber One or more input or output addresses have been forced to an On or Off state, but the forces have not been enabled.

Use caution if you enable I/O forces. If you enable I/O forces,
all existing I/O forces also take effect.


Indicator Status Description
RS232 Off There is no activity.
Solid green Data is being received or transmitted.
BAT Off For a Series A controller, the controller does not show this indication.
Solid green For a Series B controller, during power-down, the controller is saving the project to its internal nonvolatile memory. If the BAT status indicator is solid red before you turn off the power, the BAT status indicator remains solid red even during the save.
Solid red If the battery is not installed, install a battery. If the battery is 95% or more discharged, replace the battery.
OK Off No power is applied. When ready, turn on power to the controller.
Flashing red If a new controller (just out of the box), the controller requires a firmware update. See Update the Controller.

If the controller is not a new controller (previously in operation), a major fault occurred. See Clear a Major Fault.
Solid red The controller detected a nonrecoverable fault, so it cleared the project from memory. See Clear a Nonrecoverable Fault.
Solid green The controller is ok.
Flashing green The controller is storing or loading a project to or from nonvolatile memory. If the controller has a CompactFlash card, leave the card in the controller until the OK status indicator turns solid green.
