5.1 Before installation
To do installation works on the respective device you have to switch off the device and secure it from
unintended switch-on according to the appropriate operation manual! Also follow any other safety in-
structions from the user manual. If not mentioned otherwise, the specications of the Modbus TCP or
Ethernet standard apply. The installation has to be carried out in accordance with local regulations.
It's recommended to update the device software to the newest version before start the implementation
of the device in a Modbus TCP network. Modbus TCP is only supported as of software version 5.8.
The device acts as a server only. The Modbus TCP client - server principle only allows the client (e.g.
a control computer) to initiate date transmission. The respective server (respective device) then reacts
and export the requested data to the client or carries out the action required by the client.

Important: When laying the network cabling,
make sure there is sufcient distance to other
cables, especially if they are connected to the
mains!
