General information about CANopen

11.1.1 Introduction
A CANopen option is available for the all the MIS motors.
When this option is installed, the controllers include a CANopen slave. Through the
CANopen slave, all the registers of the controller can be accessed. Both implement ob-
ject dictionaries that follow the CiA DS-301 standard.
The controllers are designed to be used on a CANbus, CANopen DS-301 and CANopen
DSP-402. Do not use the modules together with CANKingdom or DeviceNet.
The MIS motors supports dynamic mapping of all objects in both 16- and 32-bit. The data
field length of a PDO can be between 1 and 8 bytes so the user can decide how to com-
bine these objects to obtain the most efficient packed amount of information in order to
decrease bus load. Please consult the section
to construct these PDO's. Also supports default mapping is supported.
Furthermore it is possible to implement a flexible register, which is fully user customiza-
ble so that the user can select single bits to monitor by a TxPDO. Read more about this
in the section
11.1.2 CiA membership
CiA (CAN in Automation) is a non-profit society. The object of the society is to promote
CAN (Controller-Area-Network) and to provide a path for future developments of the
CAN protocol. CiA specifications cover physical layer definitions as well as application
layer and device profile descriptions.
In order to receive the CAN standard, is it necessary to obtain CiA membership. The
membership fee depends on a company's number of employees. Membership runs from
January 1
by the end of a calendar year. Companies applying for membership after July 1
of annual membership.
A PDF application form can be downloaded from http://www.can-cia.org/cia/applica-
tion.html.
Note: Once you have received a license from CIA, standards will be sent on a CD and
are downloadable via member login. All of the CiA specifications can be ordered from
the following URL:
11.1.3 CANopen network
The CAN bus is a serial bus with multi-master capabilities where different products from
different manufacturers can communicate with each other. These include, for example,
devices such as PLCs, motors, sensors and actuators. Some message types have higher
priority and are sent first, for time-critical applications. New devices can easily be inte-
grated on an existing bus, without the need to reconfigure the entire network. The de-
vices are connected through a 2-wire bus cable with ground, and data is transmitted
serially.
