Safety setting for bus failure

In case of a bus failure, the setting of the last data byte of the bus outputs will be retained as long as
power is connected.

Electrical connection

The bus line is a 4-pole cable with an additional screen that must correspond to the DeviceNet
specifications and over which both information (data) and power (power supply for the low-power actuators
and sensors) will be transmitted.

The Type 1066 control head has a 5-pole Micro-style M12 round plug. The following pin configuration
corresponds to the DeviceNet specification:

Termination circuit for DeviceNet systems
When installing a DeviceNet system, attention must be paid to the correct termination circuit for the data
lines. This circuit prevents interference arising from signal reflection on the data lines. The main line must
therefore be terminated as both ends, as shown, with resistors of 120 Ω with 1/4 W power rating.
