The following list shows explicit messages that can be sent to E5AR/E5ER-
DRT Digital Controllers. These messages are used to read and write mainte-
nance information (such as Unit conduction time or total RUN time) for the
DeviceNet-compatible Digital Controller.
For details on sending explicit messages from an OMRON Master PLC, refer
to the DeviceNet Master Unit operation manual.
Note The number of digits used for the Class ID, Instance ID, and Attribute ID
depends on the master used. When sending parameters from an OMRON
Master Unit, the values are expressed as follows:
Class ID: 4-digit (2-byte) hexadecimal
Instance ID: 4-digit (2-byte) hexadecimal
Attribute ID: 2-digit (1-byte) hexadecimal
Instance ID Data (CompoWay/F command frame data)
