CANopen Master Unit
CANopen Capabilities
The table describes the LT CANopen master features:
For each additional CANopen slave:
 The application size increases by an average of 10 kbytes, which can result in a memory size
overload.
 The configuration initialization time at the startup increases, which can lead to a watchdog
condition.
Although LT does not restrict you from doing so, we recommend that you not exceed 16 CANopen
slave modules (and/or 32 TPDOs and 32 RPDOs) for sufficient performance tolerance and to
avoid performance degradation.
Maximum number of slaves on the bus 16 CANopen slave devices
Maximum length of CANopen fieldbus cables According to the CAN specification (see Cable Length
and Transmission Speed).
Maximum number of PDOs managed by the master 32 TPDOs + 32 RPDOs
WARNING
UNINTENDED EQUIPMENT OPERATION
Do not connect more than 16 CANopen slave devices to the LT.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
NOTICE
DEGRADATION OF PERFORMANCE
