bus extensions
Advantys FTB splitter boxes are of the monobloc type.
Each splitter box comprises one part for connection of sensors and actuators by
means of M12 connectors, and one part for connection of splitter boxes on CANopen
and DeviceNet fieldbuses.
These splitter boxes enable inputs/outputs to be located remotely, as close as
possible to the equipment being controlled.
CANopen bus presentation
The CAN system, initially developed for real-time exchange of information in the
automobile industry, is now being used more and more throughout industry. There
are several fieldbuses based on CAN base layers and components.
The CANopen bus conforms to international standard ISO 11898, promoted by the
“CAN in Automation” association (a grouping of manufacturers and users), and
guarantees a high degree of openness and inter-operability due to its communication
profiles and its standardized equipment.
The CANopen bus is now recognized, in Europe, as the reference standard for
building industrial systems based on the CAN concept.
The CANopen bus is a Multimaster bus, based on the Master/Slave principle.
The physical link consists of a shielded twisted pair, to which up to a maximum of
127 Slaves can be connected by simple tap-off. The binary rate varies, depending
on the length of the bus, from 1 Mbits/s for 40m (131.2 ft.) to 50 kbits/s for 1000m
(3281 ft.).
Each end of the bus must be fitted with a line terminator.
The CANopen bus is a set of profiles on CAN systems, possessing the following
characteristics:
b Open bus system.
b Data exchanges in real-time without overloading the protocol.
b Modular design allowing modification of size.
b Interconnection and interchangeability of devices.
b Standardized configuration of networks.
b Access to all device parameters.
b Synchronization and circulation of data from cyclic and/or event-controlled
processes (short system response time).
b Exchanges possible with numerous international manufacturers.
