4 Introduction
The Industrial Firewall forms the link between the IT world and the automation system and meets the
requirements of IT security as well as of the maintenance personnel in the production facility. It allows
the network in plants and machines as well as access to this network to be monitored. Its fundamental
protective mechanism is situation-dependent and physical network disconnection. It additionally
provides safe access for service purposes, allows traffic shaping and can use existing virus scanners.
4.1 Cut & Stop
In critical start-up or production phases, the WAN interface can be disconnected via a 24 V input. This
makes deliberate or inadvertent manipulation absolutely impossible.
The WAN interface is reconnected via the same input. This function makes integration in an automation
concept extremely easy.
4.2 Alarming
In the event of rule violation, the alarm signal is sent to the control system via an output. Necessary
measures can be automated directly.
Acoustic indicator lights can, for example, signal the alarm condition.
Automatically sent emails can warn of rule violation.
4.3 Event log
If the firewall is disconnected from the power supply, a non-volatile event log saves all events.
The event log can be read out both locally and via a central syslog server.
4.4 Mobile phone modem
Connection is possible via LTE/UMTS/GSM using the integrated modem.
