3.5 Sensor administration under Modbus
Preparation of the IQ S ENSOR N ET for communication with the Modbus
may require, e.g. the following:
 Creating an IQ S
ENSOR N ET system with specific assignment of
sensor numbers to sensors (see section 3.5.1)
 Creating several IQ S
ENSOR N ET systems with the identical
assignment of sensor numbers to sensors (see section 3.5.2)
 Changing the order of the sensors in an already installed system
(see section 3.5.3)
3.5.1 Creating the assignment of sensor numbers
You want to install an IQ S ENSOR N ET system and, at the same time, to
create a specific sequence of sensor number assignments to the
sensors.
3.5.2 Creating the identical assignment of sensor numbers in
several systems
You want to install several identical IQ S ENSOR N ET systems and, at
the same time, to create the same sequence of sensor number
assignments to the sensors in all systems.
1 Carry out a system start without any sensors (see System
operating manual, chapter Installation).
2 Connect the sensors to the system in the required order. For
each sensor, wait until the sensor is recognized by the system
(see System operating manual, chapter Installation).

2 Connect the sensors to the system in the required order. For
each sensor, wait until the sensor is recognized by the system
(see System operating manual, chapter Installation).
3 Repeat steps 1 and 2 for all other systems and, while doing so,
keep to exactly the same order when connecting the sensors.
