Enclosure Shield
Incorrect parameterization can damage the communication partners!
The voltage levels are −12 V and +12 V for RS-232, and −5 V and +5 V for
RS-485.
If the controller interfaces differ from those of the communication partners
(RS-232 <> RS-485 or RS-485 <> RS-232), this may damage the interface of the
communication partner.
Therefore, always ensure that the controller interface matches those of its
communication partners when configuring these items!
DC/DC converters and optocouplers in the fieldbus interface electrically isolate
the fieldbus system and the electronics.
