3 The "PC-based automation" system
Industrial PCs (IPCs) are increasingly finding their way into automation technology. With
their scaling characteristics and the possible combination of visualisation and control in
one device, industrial PCs offer clear advantages for many applications.
Lenze industrial PCs are available with the following software equipments:
 Industrial PC as component (optional with operating system) without any further
software
 Industrial PC as visualisation system
 Industrial PC as control and visualisation system
The "PC-based automation" system allows the central control of Logic and Motion systems.
For this purpose, Lenze provides coordinated system components:
 Industrial PCs as control and visualisation system
– The IPC is the central component of the PC-based automation which control the
Logic and Motion functionalities by means of the runtime software.
– The IPC communicates with the field devices via the fieldbus.
– The IPCs are available in different designs.

Note!
Moreover, the HMI series EL 1xx PLC belongs to the "PC based automation"
system. These devices differ considerably from the industrial PCs in performance
and various other details. However the devices of the HMI series EL 1xx PLC are
able to fulfil smaller control functions.
