Total line lengths according to the DeviceNet specification
The maximum total line lengths (sum of main and drop lines) of a network depend on the baud rate.
Maximum line lengths
1)
According to the DeviceNet specification. When using another cable type, lower maximum values
apply (refer to the DeviceNet specification).
DeviceNet
Explanation of terms
• DeviceNet is a field bus system that is based on the CAN protocol (Controller Area Network). It makes
possible the networking of actuators and sensors (slaves) with a master control unit (master).
• In the DeviceNet, the Type 1066 control head is a slave device according to the Predefined
Master/Slave Connection laid down in the DeviceNet specification. Polled I/O, Bit Strobed I/O and
Change of State 4 (COS) are supported as I/O connection types.
• In DeviceNet, a differentiation is made between cyclic or event-controlled transmitted process messages
of higher priority (I/O Messages) and non-cyclic management messages of lower priority (Explicit Mes-
sages).
• The protocol corresponds to
DeviceNet Specification Release 2.0
NOTE
A diskette with configuration files (BUE1066.EDS and BUE1066.ICO) is always delivered
with the DeviceNet models. You can also obtain these files over the Internet.
