CANopen bus master module<br />
Presentation<br />
Master module TWD NCO1M for the CANopen bus<br />
allows <strong>Twido</strong> programmable <strong>controller</strong>s version ≥ 3.0,<br />
compact base <strong>controller</strong>s TWD LCpA 24/40DRF and<br />
modular base <strong>controller</strong>s TWD LMDA p0Dpp, to act as<br />
CANopen master.<br />
The bus consists of a master station, the <strong>Twido</strong><br />
<strong>controller</strong> and slave stations. The master is in charge of<br />
con guration, exchanges and diagnostics on the<br />
slaves.<br />
CANopen<br />
The CANopen bus is a communication type bus and<br />
allows management of various slaves such as:<br />
b Discrete slaves,<br />
b Analogue slaves,<br />
b Variable speed <strong>controller</strong>s,<br />
b Motor starters,<br />
b ….<br />
CANopen<br />
The <strong>Twido</strong> CANopen master controls up to 16 slaves,<br />
each with an input PDO (Process Data Object) and an<br />
output PDO.<br />
If a slave has more than one PDO, the maximum<br />
number of slaves is reduced by an equivalent number.<br />
CANopen conformity class<br />
Schneider Electric has de ned the conformity classes for CANopen master and slave<br />
devices. Conformity classes are used to identify the services and levels of service<br />
supported by each CANopen device or product. These services are described in<br />
section 4 of our “Machines & Installations with industrial communications” catalogue.<br />
The table below shows product combination possibilities according to their conformity<br />
class.<br />
Conformity class Slave product<br />
S10 S20 S30<br />
Master<br />
product<br />
M10<br />
M20<br />
M30<br />
Combination possible<br />
Use restriction: The use of a slave device with a master that has a lower conformity class<br />
(e.g. S20 with M10), or of a master device with a slave that has a higher conformity class (e.g.<br />
M10 with S20), limits the level of service to that of the lower conformity class.<br />
