3 Introduction
3.3 System description
The modules in the Q.bloxx series have been developed for indus-
trial and experimental measurement and test engineering, in par-
ticular for multi-channel measurements of electrical, mechanical
and thermal si
gnals on engine and component test-rigs as well as
for monitoring processes and long-term supervision. The modules
A123, A124, A127 and A128 are specially designed for measure-
ments at high voltages.
Voltages of up to 1200 V may be present on the connec-
tions of the modules A123, A124, A127 and A128.
Before connecting or disconnecting cables make sure that
all sources of power are Locked Out.
The individual modules can be combined to form one system as
required. You can connect up to 32 or 64 modules to one of the
Test Controllers Q.gate, Q.pac or Q.station 101 and then address
them from a PC or PLC via a single interface. Alternatively, it is
also possible to address single modules directly via the serial
interface.
On all modules the power supply, bus interface and the inputs
and outputs are el
ectrically isolated from one another. The use
with Q.gate and Q.pac is explained in this manual. Please use the
manual provided specifically for this module when operating the
Test Controller Q.station 101.
3.3.1 Operating the modules via Q.gate
You can connect up to 16 modules to each of the two serial inter-
faces (UARTs) of the Q.gate Test Controller (Fig. 3-1 and Fig. 3-
2). For a direct connection on DIN mounting rails (DIN 35 mm
rail according to DIN EN 60715) a special plug-on socket
is also
available: the Q.bloxx Extension Socket QES. This means that you
can plug all 32 modules onto a mounting rail directly adjacent to
one another. The Q.bloxx Extension Socket QES is plugged in
centrally between the other sockets; the power supply of the sec-
ond group of up to 16 modules also takes place through the
extension socket.
You can communicate via Ethernet with the connec
ted modules
from the Q.gate Test Controller. The maximum cable length
between the measurement modules and the Q.gate depends on
the desired baud rate:
