Section 5: Connection

Depending on the order there are the following connections possible:

Standard Design

The connection of the RTS control unit to the PROFINET fieldbus at the field level
is done via 4-pin, D-coded, M12 connectors, to meet the required high degree of
protection (see IEC 61076-2-101).
The female side is on the device, and the male side on the cable side.
Two equivalent M12 connectors, which are internally wired to a hub, are located on
the RTS control unit with PROFINET. With this, a line structure can be implemented.
Which connection is used is irrelevant for the function.

The devices are connected via crossover cables, i.e.:

•
•
The cable types recommended are standard patch cables (twisted pair, S/UTP, AWG26,
Cat5e). The cable shield has to be connected to the actuator housing over the
connector housing. It is important to ensure that there are no potential differences
between the individual devices in the PROFINET network so that no transient currents
flow over the cable shield.
