2.2.2
CAN Bus (HG 73350)
The CAN bus is connected to the device via two 5-pin A-coded M12 connectors male/
female (see „Casing interpreter HG 73350/HG 73351“ on page 6.). There they can be
found as BUS1 and BUS2, which are allocated as follows:
The connectors of the inputs BUS1/BUS2 are connected in parallel, i.e. there is no in-
put or output. If the interpreter is installed at the end of the bus line, a CAN terminator
has to be installed. Those terminators can be ordered form different manufacturers
and are available for most plugs and jacks. The CAN connectors can also be used as
power supply.
ATTENTION!
Do not c24V to pin 4 or 5!
2.2.3
Profibus (HG 73351)
Two 5-pin B-coded M12 male/female, indicated as BUS1 and BUS2 in Figure 1 above.
There they can be found as BUS1 and BUS2, which are allocated as follows:
The connectors of the inputs BUS1/BUS2 are connected in parallel, i.e. there is no in-
put or output. If the interpreter is installed at the end of the bus line, a bus terminator
shall be provided. Those terminators can be ordered from different manufacturers and
are available for most plugs and jacks.
