Destination node address (command): The node address of the destination
of the explicit message. (The node address of the local Master Unit is specified in
the control data for the CMND(194) or IOWR instruction, but the node address of
the actual destination is specified here in the FINS command.)
Service code (command, response): A service code defined for DeviceNet. In
a normal response, bit 15 of the service code specified in the command will be
turned ON and returned. In an error response, 94 hex will always be returned.
Class ID (command): The class ID of the destination of the explicit message.
The class ID is always 008A Hex when reading or writing the DeviceNet Inter-
face Unit’s PT memory.
Instance ID (command): The instance ID of the destination of the explicit mes-
sage. The instance ID is always 0001 Hex when reading or writing the Device-
Net Interface Unit’s PT memory.
Service data (command, response): The data defined for the services codes.
No. of bytes received (response): The number of bytes received from the des-
tination node address (local node).
Destination node address (response): The node address of the OMRON
Special I/O Slave Unit or slave manufactured by another company to which the
explicit message was sent is returned.
General Error Code (response): The following error codes may be returned.

The data string is too short or there is an odd
number of bytes.

20 Hex
Invalid parameter

returned when reading PT memory.
16 Hex
Object does not exist
The Class ID is not supported.
Note
1. Unlike other FINS commands, this command is addressed to the local
node’s DeviceNet Master Unit. The actual destination of the explicit mes-
sage is given in the command data, as described above.
