The establishment of the VPN tunnel can also be controlled via the digital input, e.g.
using a button. When the button is closed, voltage is applied to the digital input and the
LED of the digital input lights up. The lit LED indicates that signal 1 (TRUE / HIGH) is
applied. Signal 1 triggers an event on the device with which the establishment of the
VPN tunnel is controlled. You will find information on connecting and the maximum
current load in the operating instructions of the devices.
Requirement
• In "System > Events > Configuration" for the "Digital Input" event "VPN Tunnel" is

Description
The device attempts to establish a connection to a
partner when necessary. The receipt of requests for
VPN connection establishment is also possible.
For the configured local and remote subnets, an entry
is created in the routing table. If a node attempts to
send data packets via the VPN tunnel from one of the
networks, the VPN connection is established. The
settable timeout has the effect that after this time
without any further data packets the VPN tunnel is
terminated again.
Connection establishment is controlled via the digital
input (DI).
The device adopts the settings of the SINEMA RC
server. You configure the settings on the SINEMA RC
Server in "Remote Connections > Devices". You can
find additional information on this topic in the
operating instructions "SINEMA RC Server".
The device establishes a VPN connection to the
SINEMA RC Server. The VPN tunnel is established
permanently
