Example: Evaluating an Error Message by a Diagnostic Register
In the application program of the controller, the error register is monitored. When bit 9
"Error Output Driver" has been set, the first JX3 module having got an error message, is
searched for in a loop. After this, the I/O module number and the number of the status
register is calculated.
