The Shared Memory
Operating Manual ProNumeric XCI 600 Version 07/16

You can access the individual sections and components of the shared
memory with the
Globale_Variable.Section.Components
notation. For
example, the PLC program can read the version number of the controller
operating software from the
cncMem.plcSect.lOSVersion
variables. For
more information about the integration of shared memory into the
MULTIPROG programming system, see page 33.
Visualisation systems have access to the shared memory via the OPC
interface. The OPC server cannot handle structured variables, so the whole
data structure of the shared memory is mapped out as a one-dimensional
list. The names are composed of two parts separated by an underline from
each other. The first part is the access path, while the second part is
identical to the component name of the PLC variable. For example, the
version number of the operating software could be read from the OPC
variables
cmpS_lOSVersion
.
