4 Introduction

The Industrial Firewall forms the link between the IT world and your local systems and meets the
requirements of IT security as well as of the maintenance personnel. It allows to control and access the
networks to be monitored. Its fundamental protective mechanism is the situation-dependent 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 Ethernet uplink can be disconnected via a 24 V input. This
makes deliberate or inadvertent manipulation absolutely impossible.
The uplink 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 Eventlog

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. The SIM card slot is on the
rear of the device.
