definition

12.1.

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.
