Data type
‣ If the CAN port functions as a slave, it has the following functions.
It supports the standard CANopen protocol DS301 V4.02.
It supports the NMT (network management object) service.
It supports the NMT state control.
The state of DVP-ES2-C in the CANopen network is controlled by a master.
It supports the NMT error control.
Heartbeat is supported, but Node Guarding is not supported.
It supports the PDO (process data object) service.
The PDO message is used to transmit the immediate input data and output data.
It supports 8 TxPDO at most, and 8 RxPDO at most.
The PDO transmission type: The synchronous mode, and the asynchronous mode
It supports the service of reading the emergency from a slave.
If an error or an alarm occurs in DVP-ES2-C, the master is notified through the emergency.
7.1.2 The Input/Output Mapping Areas
DVP-ES2-C as a master supports 16 slaves at most, and the slave node ID range from 1 to 16. The
output mapping areas are D6250-D6476, and the input mapping areas are D6000-D6226.
