4 Connection of Modules
Sensor and actuator modules are connected to the
BlueBox via CAN-bus cable. The CAN-bus (Control-
ler Area Network) belongs to the field buses and is
an asynchronous, serial bus system.
∗
The connection to the BlueBox is an M12 panel
socket (see
3.2 Connections BlueBox T4
or
3.3 Con-
nections BlueBox T4 Basic
).
The first and last element must be terminated in a
bus structure (see
4.3 Termination of the CAN-bus
).
In most cases, the CAN network is built up as a bus
structure. For other structures, the network topol-
ogy must be CAN-bus-compliant.
To connect a module to the BlueBox, plug the M12
cable plug from the CAN-bus cable into the M12
panel socket of the BlueBox.
The other end of the CAN-bus cable can be con-
nected to a module in two ways:
1. Connection with M12 cable plug
see 4.1
Note the correct PIN assignment of the cable
plug.
see 3.2 or 3.3
When using a cable of type LiYCY 2x2x0.5 mm²
(Article- No. 339 0001) the colour coding according
to the table below applies.
2. Connection with clamp sockets
see 4.2
Note the correct terminal assignment in the
module based on the circuit board labelling.
When using a cable of type LiYCY 2x2x0.5 mm²
(Article- No. 339 0001) the colour coding according

When using the active repeater from GO Systemelek-
tronik, the CAN network in the repeater is not a bus, but a
star. see

4.1 Connection with M12 Cable Plug
On the bottom of the module housing there is a
four-pole M12 panel socket. In this socket the four-
pole M12 cable plug of the CAN-bus cable or an
M12 Y-splitter is plugged in and is fixed by turning
the union nut.
Module connection with M12 cable plug
(final module)
The connection as a pass module is made with an
M12 Y-splitter.
