Insert the Shared RAM
To get full access to the the predefined variables, it is appropriate for
startup to insert the shared RAM structure in the project.
The shared RAM has a comprehensive data structure that is used for
communication between the PLC, CNC and visualisation systems.
Data areas such as the version number, error page and logbook can
also be accessed via the shared RAM.
An introduction on the subject of shared RAM is given on page 133. A
more detailed description of all variables of the shared RAM is
available as online help in the "Schleicher dialog" software. This can
also be called using the help menu of MULTIPROG.
The corresponding data types and variables must be inserted in the
PLC project to enable access to the variables of the shared RAM.
These are not yet included in the project templates of MULTIPROG.
They must be inserted in the PLC project by the user with the aid of
the shared RAM add-ons for MULTIPROG. It must be ensured that
the user works with the shared RAM version that is suitable for the
controller software.
Insert the shared RAM data types and variable in a PLC project via the
Extras / PLC/MC/CNC shared RAM menu
