Definition12.1.
The DeviceNet is a field bus system which is based on the CAN protocol (Controller Area Network). It enables •
actuators and sensors (slaves) to be networked with higher-level controllers (master).
The control head in the DeviceNet is a slave device according to the Predefined Master/Slave Connection Set •
stipulated in the DeviceNet specification. Polled I/O, Bit Strobed I/O and Change of State (COS) are supported
as I/O connection variants.
With DeviceNet it is necessary to differentiate between cyclical or event-driven high-priority process messages •
(I/O Messages) and acyclical low-priority management messages (Explicit Messages).
The protocol process conforms to the • DeviceNet specification Release April 2010.
Electrical connection option 12.2.
Cable gland with multi-pole connection
(M12 plug according to IEC 61076-2-101, 5-pole)
