Node-RED LogicLab Documentation
FOREWORD
The cross-reference functions allows to identify and list all the usages (references) of the symbols (vaiables, POUs, type definitions etc.) of a PLC application. For each symbol all its references inside the application are listed, for each reference the following elements are reported:
- referencing block (POU or variable group)
- position inside the block (e.g. the line inside the source code)
- access type, read or write
Availability
The cross-reference is available on LogicLab releases starting from 4.0.x.
