DEVICENET DESIGN
12.1.
Definition
• 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.
