7 CANopen Function and Operation

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	b7	b6	b5	b4	b3	b2	b1	b0
Node	Node 8	Node 7	Node 6	Node 5	Node 4	Node 3	Node 2	Node 1
Bit	b15	b14	b13	b12	b11	b10	b9	b8
Node	Node16	Node15	Node14	Node13	Node12	Node11	Node10	Node 9

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.

¾The error code of every node is displayed through the corresponding special register and the relations between special register and corresponding node are shown below.
