ERbic SafetyBUS p
The SafetyBus p utilizes the advantages of the CAN bus. A
protocol has been developed by Pilz that satisfies safety
engineering requirements.
A larger cable cross section of 0.75 mm
2
is specified to cover
longer distances. Only the 3 conductors necessary for the bus
are terminated within the connector (HLG).
