COB-IDs vary according to communication address, but for one command, the COB-IDs are within a certain range.
Note:
The commands described in this manual are all data frames if it is not specified that they are remote
frames.

Command specifier (CS)
Node-ID (Node ID)
Description
In this command, the COB-ID is 0×00. If Node-ID is set to 0, the command is broadcast to all CANopen slave nodes, and
each slave node must execute the NMT command. Table 6-7 describes the function of each CS.

0x80
Enables a slave node to enter the pre-operation state.
0x81
Resets a slave node.
0x82
Resets communication of a node.
Example
For example, the command to enable EC-TX105, whose node ID is 3, to enter the pre-operation state is described as
follow.
