NOTICE
Device damage due to condensation
Humidity may cause condensation on the device if temperature balance has not been
reached. Condensation may damage the device when it is connected to the power supply.
Do not connect the device to the power supply until temperature balance has been reached.
To achieve temperature balance, place the device in the operating room for a period of at
least two hours.
Note
RS 485 termination recommended
In order to avoid reflection on the bus cable, we recommend fitting a 120
Ω terminating
resistor at the beginning and end of the bus cable.
To establish Modbus RTU communication, the communication parameters must be known.
These include baud rate and format. Furthermore, you must have entered the slave address
in the device.

Notes
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks. In order to protect plants,
systems, machines and networks against cyber threats, it is necessary to implement – and
continuously maintain – a holistic, state-of-the-art industrial security concept. Siemens’
products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected
to an enterprise network or the Internet if and to the extent such a connection is necessary
and only when appropriate security measures (e.g. firewalls and/or network segmentation)
are in place.
