Overview
Understanding the error log will aid in troubleshooting problems with the RC8(A) controller.
The error log itself is not responsible for the controller being in an error state, rather it is a list of errors that have been recorded by the controller.
The error log in the RC8 controller records and displays up to 1000 errors. Every error that is recorded includes a date and time stamp, call, error code including error level, error message, and details. The error log operates by displaying the most recent error at the top of the log. As new errors are generated, older errors in the log will be indexed downward. When the 1000 error limit is reached, the oldest errors in the log will be deleted as new errors are generated.
If the error was generated while running a program, the error may note “Program” in the Call section. If so, the program that was running while the error occurred and the line of code that generated the error will display in the Detail section.
The error log utilizes the date and time setting of the controller. The current date and time will be logged with an error when it is generated. If the date and time setting within the controller is incorrect, the date and time setting logged with an error will be incorrect.
A controller’s reaction to errors will differ depending on the level of error. Level 1 through level 4 errors can generally be resolved by correcting the issue such as releasing the emergency stop button, turning on the motor power, etc. Level 5 errors are significant errors which require the error to be resolved and controller power to be cycled.
When troubleshooting a controller that is generating errors which prevent normal operation, the errors generated on the current power cycle are the errors of interest. To identify a power cycle in a controller, look for the most recent 85480003 (Instantaneous blackout detected) error. Once the most recent 85480003 error is found in the list, all errors above this error in the list should be taken into consideration when troubleshooting. Level 5 errors should be given special attention, as level 5 errors prevent any controller operation until the cause of error is resolved, and power is cycled.
Full sized teaching pendants will display detailed error information on the pendant.
Mini Pendants can only display the error code with error level.
Obtaining a new Wincaps III backup of the controller will allow the full error log to be viewed with detailed error information.
