DEVICENETDEVICENET

CAN-based multi master system for transmission of cyclic and acyclic messages

Supports different kinds of communication (Polling, Strobe, Change of State, Cyclic Data Transfer)

Technical Data:Technical Data: Total extent: max. length of the main line 3 km

with the use of repeaters Length of the trunk line: 500m-125kBit/s ; 125m-500kBit/s

(trunk cable use only) Topology: Line Transmission rate: 125-, 250-, 500 kBit/s Cycle time: dependent on the number of slaves number of devices: up to 64 (e.g. 1 master, 63 slaves)

Communication: Polling

The master communicates with the slaves one after the other.

Communication: Strobe

The master sends a broadcast message simultaneously to all slaves.All slaves with inputs send their input data back to the master.

Advantages: The most flexible system concerning the variety of communication

(Polling, Strobe, Change of State, Cyclic Data Transfer) Efficient diagnosis functions High data security (HD=6) Response monitoring (slave) Plug & Play configuration by EDS-files Automatic detection of faults and redundant addresses

Disadvantages: Line structure small spatial extension Necessity of setting address and baud rate Software burden (hardly learnable)
