Fig. 5 shows the connection of transducers DME 440 to
the MODBUS. The RS 485 interface can be realized by
means of PC built-in interface cards or interface converters.
Both is shown using i.e. the interfaces 13601 and 86201 of
W & T (Wiesemann & Theis GmbH). They are configured for
a 2-wire application with automatic control of data direction.
These interfaces provide a galvanical isolation and a built-in
termination network.
Important:
– Each device connected to the bus must have a unique
address (1 to 247, standard factory setting 247).
– All devices must be adjusted to the same baudrate.
