Automation system
An automation system is a programmable logic controller that consists of at least one CPU,
various input and output modules, as well as operating and monitoring devices.
AWP
Automation Web Programming
AWP commands
Special command syntax for data exchange between CPU and HTML file.
Configuration
Systematic arrangement of individual modules (design).
CSS
A CSS (Cascading Style Sheet) specifies how an area or content marked up in HTML is
displayed.
Device
Device that can send, receive or amplify data via the bus, e.g., IO controller.
Diagnostics
The detection, localization, classification, visualization and further evaluation of errors,
malfunction and alarms.
Diagnostics provides monitoring functions that run automatically during plant operation. This
increases the availability of plants by reducing commissioning times and downtimes.
Firewall
A firewall is used to restrict the network access based on sender or target address of the
used services. The firewall decides based on specified rules which of the network packets it
handles are forwarded and which are not. This way the firewall tries to prevent unauthorized
network access.
It is not the function of a firewall to detect attacks. It only implements rules for network
communication.
