Overview

The "PlcHelperBC.lb6" library contains a number of functions which provide direct access to memory areas in the PLC controller's (BCxxxx) PLC runtime system.

 

Comment

The fact that these functions allow direct access to the physical memory means that special care is called for in applying them! Incorrect parameter values can result in a system crash, or in access to forbidden memory areas.
