System structure
This chapter provides you with an overview of the basic system structure of the Lenze "Controller-
based Automation" system. The system consists of an Engineering PC, a Controller and the devices
communicating with the Controller via the fieldbus.
[4-1]
* The PROFIBUS fieldbus driver can only be accessed via PLC (Logic/Motion). Access via EASY Starter and VisiWinNET®
Runtime is not provided.
Controllers and field devices form the automation system to be commissioned via the Engineering
PC. The Engineering PC is a PC/Laptop with Windows® operating system and network connection.
The Engineering PC comes installed with the Lenze
for parameter setting,
configuration, programming and diagnostics.
The Controller with the PLC (Logic/Motion) is the central control section, consisting of the PLC
runtime program (
Runtime software of the Lenze Controllers
) with the running PLC
application.
Device-internally, the Controller comes with a data manager for configuring and managing the data
of the automation system. The data manager and the fieldbus driver enable the PLC (Logic/Motion)
to access the system components and the field devices.
The fieldbus (Logic/Motion) enables the Controller to read and write the parameters of the
connected field devices.
