DeviceNet
31. DESCRIPTION
31.1. Explanation of term DeviceNet
DeviceNet
• 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 Type 8792/8793 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 sup-
ported as an I/O connection variant.
• 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 2.0.
