CANopen machine bus
The CANopen bus is configured using dedicated SyCon (1) software, which should
be ordered separately, reference SYS SPU LF
p CD28M.
This software is used:
b To describe all devices connected on the bus.
b To generate the “.CO” file including the informations relating to the devices
connected. This extension file is imported into the PLC application via the
PL7 Micro/Junior/Pro programming software.
If the configuration file is too large in relation to the TSX Micro/Premium processor
capacity (see characteristics table), it is possible to load the master configuration
directly by inserting the TSX CPP 110 card in a PCMCIA port (type III) on the PC on
which SyCon software has been installed.
In PL7, it is possible to configure the CANopen bus card so that the PLC
processor/TSX CPP 110 card exchanges are executed at the same rate as the
master task or the fast task.
The process data exchanged with the slaves can be accessed by %MW standard
words, the number of which depends on the type of processor and the task in which
the module has been declared. PL7 standard function blocks are used to define the
device parameters.
Nota : In addition to supporting the CANopen protocol which uses V2.0A standard CAN
identifiers on 11 bits, the card enables direct access to the CAN link layer via CAN V2.0B
identifiers on 29 bits, used by the majority of CAN devices. In certain applications this enables
simultaneous control of CANopen devices and dedicated CAN products.
(1)The SyCon field bus configurator software also makes it possible to describre the I/O
configuration of Profibus DP bus for Modicon Premium and Modicon Quantum platforms and
the I/O configuration of I
NTERBUS bus for Modicon Quantum platform.
(1) This size can be exceeded if the configuration is loaded in the memory of CANopen PCMCIA
card via the SyCon software.
