3.5 Connecting system components
3.5.1 General information
The IQ S
ENSOR
N
ET
system components are connected to form a functioning
unit in the following ways:
 Stacked mounting of MIQ modules
Up to three MIQ modules can be installed and mechanically connected with
one another to form a stack at a single location. The contacts on the front and
rear automatically create the electrical connection between the MIQ modules
in the stack (section 3.5.2).
 Distributed mounting of MIQ modules
Individual MIQ modules or an assembled module stack are installed at vari-
ous locations (for example, a central control unit and an MIQ branching mod-
ule for connecting IQ sensors at the edge of the basin). The spatial distance
is bridged with the aid of the SNCIQ or SNCIQ/UG cable (section 3.5.3).
 Connection of IQ sensors:
IQ sensors are connected to an MIQ module with the aid of the SACIQ cable.
This cable is available in different lengths. The MIQ module must have a free
SENSORNET connection on the terminal strip. On the sensor side, the con-
nection is made with a plug that is standard for all IQ sensors (section 3.5.4).
The connection of the system components is described in the fol-
lowing sections exclusively with examples of the connection of MIQ
modules.
These descriptions similarly apply to system components that are
not mentioned separately in the examples (e.g. universal transmitter
DIQ/S 281).
Distributed mounting is only allowed in a star configuration. The
system must nowhere be closed to form a ring. Only use the
assembly material provided for the installation.
