Explicit Message Command
Explicit Message Response
• The command data is written in DM words starting from D01000 in the
CPU Unit memory, and the response data is stored in DM words starting
from D02000.
• If the command does not end normally, the end code is stored in DM
words D00006, and the send command is re-executed.

6-5 Sending Explicit Messages
The following list shows explicit messages that can be sent to the DeviceNet
Communications Unit. These messages are used to read and write mainte-
nance information (such as Unit conduction time or total RUN time) for the
DeviceNet Communications Unit and Temperature Controllers.
For details on sending explicit messages from an OMRON Master PLC, refer
to the corresponding DeviceNet Master Unit operation manual.
