
While the special auxiliary relay M1349 of DVP-ES2-C is ON, the CANopen function is
enabled and D9980~D9998 will be used as the special registers as the table shows below.


As a master, DVP-ES2-C supports maximum 16 slaves ranging from node 1 to node 16.
D9998 can be used for monitoring the state of nodes from 1 to 16 in the network. And the 16
bits of D9998 corresponds to 16 slaves and the corresponding relations of them are shown
below.

Bit b15
Node Node16
When the node in the master node list is normal, the corresponding bit is OFF; when the node
in the master node list is abnormal (E.g. Initializing fails or slave is offline due to other
abnormality), the corresponding bit is ON.

The error code of every node is displayed through the corresponding special register and the
relations between special register and corresponding node are shown below.

Description
1. Check whether the wiring of the CANopen bus
cable is correct.
2. Check whether the baud rate of the master is
the same as that of the slave.
3. Check if the configured slaves have connected
to the network.
4. Check if any slave is offline.
1. Check whether the CANopen bus cable is a
standard one.
2. Check whether both ends of the CANopen bus
are connected to the terminal resistors.
1. Check whether the CANopen bus cable is a
standard one.
2. Check whether both ends of the CANopen bus
are connected to the terminal resistors.
3. Check whether there is much interference
around the CANopen bus cable.
1. Check whether the wiring of the bus cable in
the CANopen network is correct.
2. Check whether the baud rate of the master is
the same as that of the slave.
