2.2.5. DALLAS Bus

The DALLAS Bus is provided with one master unit and one or more slave units. The
equivalent connection of the slave unit is shown in the diagram, the actual master unit
consists of a processor. Each of the slave units has to have an open-collector or a
three-state output. The common collector resistor (pull-up) is connected on the master
unit side. The DALLAS bus has just one wire to which all the external slave units are
connected. The length of the wire can normally be approx. 100 m. If a telephone cable
with the wires twisted into pairs is used (capacity approx. 30 pF/m), the distance
between the mater unit and the slave unit can be up to 300 meters.
The ID keys have a 16-digit
hexadecimal number marked on
the front side. The thermometers
have the number on an ID tag.
The external units can be added
to GB 060 using the configuration
tools in GB 060 Control Panel
software delivered
device.

2.2.5.1. Digital Thermometer ED 060 100

Up to 10 thermometers can be connected to a GB 060 unit at a time.
Temperature data retrieved from the
sensor is treated by the automaton as
an analogue input. An upper limit and
a lower limit can be set up for each
analogue input. An increase of the
analogue value to the upper limit or
lower limit will be interpreted by the
automaton as an event.
