3 The "PC-based automation" system
Industrial PCs (IPCs) become more and more important in the field of automation
technology. Due to their scaling options and various combinations of visualisation and
control on one device, industrial PCs provide clear advantages for many applications.
Lenze industrial PCs are available with the following software equipment:
 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 enables 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 controls 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 Z 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.
