No internal cabling work is required for any of the DeviceNet designs (cable with multi-pole connection), which
makes installation and start-up on site considerably easier and quicker, reducing the risk of leaks.
However, you will require the correspondingly assembled cable sets with the pin assignments described below:

Multi-pole connection Devicenet

The control head features a 5-pole multi-pole circular plug (M12 x 1 circular plug, 5-pole, male) to a 80 cm long
cable.
The configuration conforms to the DeviceNet specification.
