Glossary
K
Catalogue A catalogue contains descriptive information on all element types that form
an »Engineer« project. The »Engineer« uses various catalogue types, e.g. for
devices, device modules, technology applications, function blocks, and
motors. Each catalogue is labelled by versioning.
Catalogue package A catalogue package consists of several related catalogues and is named and
versioned. Multiple versions of a catalogue package can be added to an
»Engineer « installation. Every »Engineer« project can use an optional number
of catalogue packages.
Communication unit Generic term for Lenze function modules and communication modules.
Function module
Communication module
Communication module Extension module which for instance extends a controller by a
communication interface. On its own (i.e. if not equipped with a device) it does
not fulfil a function and is not capable to communicate.
M
Machine application Implementation of a functionality which is generated by the interaction of
several communication-capable devices. A machine application is defined by
the (device) applications involved and the exchange of application variables
between them.

names of menus that open with a mouse-click.
N
NMT Abbreviation for "Network Management": Services and protocols for
initialisation, configuration, management and network monitoring within a
CAN network according to the master/slave principle.
CAN
O
OLE Abbreviation for "Object Linking and Embedding": Insertion of functional
objects in other applications, e.g. a Microsoft® Excel table into a Microsoft®
Word document.
OPC Abbreviation for "OLE for Process Control": Defines an interface based on the
Microsoft® Windows® technologies OLE, COM and DCOM which enables data
exchange between different automation devices and PC programs without
driver and interface problems.
The OPC server provides the data, the OPC client receives them.
COM
DCOM
OPC tunnel OPC server and OPC client can be on different PCs networked via Ethernet.
Communication between the PCs requires a special DCOM configuration. For
OPC communication from several computers, Lenze uses an OPC tunnel that
does not require any configuration.
