NETLink S7-Compact - User Guide
To able to access a NETLink S7-Compact with the NETLink S7-Compact driver, a station must be set up
first. This station is virtually and is not stored in the NETLink S7-Compact Gateway hardware – it
permits easier differentiation if several NETLink S7-Compact devices are used.
Alternative ports can be set with the option Internet teleservice. If, for example, several NETLink S7-
Compact devices are located in a network behind a router/switch, these can also be addressed with a
port addressing (PAT) adapted here.
The router/switches used must be appropriately configured for this by the responsible network
administrator, so that all TCP/IP packages addressed to the router/switch via a predefined port are
forwarded by this to the NETLink S7-Compact located behind it.
When the NETLink S7-Compact is connected in the local network (LAN) or is not located behind a
router/switch, the Internet teleservice option must be deactivated.
Internet tele servicing to networks outside of the LAN should always be realized through secured
and encoded procedures, such as VPN!
[OK] stores this station, which can now be used.
It is easier to search for an existing NETLink S7-Compact device in the local area network. Just click
the [Search NETLink PRO Family...] button.
