General Architecture of the CANopen Field Bus
(Original Document)
At a Glance
The CANopen architecture consists of:
NOTE: It is also possible to connect several TSX CPP 110 PCMCIA cards on the bus, with one as master and all the others in listen mode. The cards in listen mode enable the Premium PLCs to which they are connected to know the status of the bus and the bus slaves at all times.
CANopen allows 128 devices (namely the bus master abd 127 remote slaves).
Transmission speed strictly depends on the bus length and the type of cable used.
NOTE: To configure a CANopen bus, use the Sycon software, version 2.8 or higher.
