TB258 Rev1 How to troubleshoot Custom PLC 9XXX Error Messages in your
CNC11 PLC Program
Purpose
 To teach you how to look at your CNC11 PLC program and figure out what is causing your custom PLC 9XXX error
message  So you can fix the problem and get your system up and running
Example
You have a T400 with a tool turret and you are getting a "9104 ATC TIMEOUT" error message
How to determine what is causing the Error
1 Â Locate your PLC source file in the CNCM mill or CNCT lathe and open in your text editor
2  At the beginning of the program you will find the "Constant Definitions" this is where your custom PLC messages are defined  In our
example we had 9104 so look for the last 3 digits 104 Â To find the line in the program that says " ATC_TIMEOUTÂ Â Â Â Â Â Â IS 26625; 1 +
256*104 " Â
3  Now highlight "ATC_TIMEOUT" and search the PLC program  To find the code that is causing the error
Note  If your displayed message does not match the error defined the PLC program you have the wrong plcmsg txt file or it has not
been modified to match your PLC program
