2.1.4 Troubleshooting (log book)
Overview
The log book is a file (Error.com) to which error messages generated by syntax interpretation
are written. The operator himself must set up the file in the comment directory (HMI
Advanced).
Example
DEF VAR1 = (R)
DEF VAR2 = (R)
LOAD
VAR1 = VAR2 + 1
Syntax
The system does not start to interpret syntax until the start softkey has been defined and a
dialog with start and end identifiers as well as a definition line has been configured.
2-4
; Definition of the start softkey (optional)
; Definition of the dialog
; Definition of variables
; Description of the blocks
; Definition of a softkey menu
; Error message in log book, as VAR2 has no value.
