Issue
For various reasons sometimes it is necessary to clear the error log in the controllers.
NOTE: First generation controllers such as the CX9200 and CX9900 (NetController 1) and Infinet1 devices do not support the error log utility, this article does not apply to those controllers.

Error log is cleared by setting the Errors system variable to 0 (zero)
NOTE:
If the Errors system variable has a non zero value all that is required is to reset it to 0
If the Errors system variable is at 0 then it has to be changed to a non zero value before it can be reset to 0
One easy way to generate an error is to create an InfinityProgram that attempts a DIVIDE BY ZERO
I.e.
Program is AutoStart and FallThru
Numeric N
n = 1/0
Create the InfinityProgram above in the controller, once the program saves and runs it will be disabled and the Errors system variable will increment by one.
Remember to delete the program as it is no longer needed
