2.2.7. Assembly Object (For Class 1 Interface)
The EtherNet/IP specification requires that all Class 1 interfaces be provided through the Assembly Object
interface. The Assembly Object interface is used to directly tie Vendor Specific objects to a standard interface,
which the EtherNet/IP controller, or PLC, uses to communicate to the device.
For the DeviceMaster EtherNet/IP-Modbus gateway, the Assembly Object corresponds to the Serial and
Socket Data Transfer objects. Each instance of the Assembly Object corresponds to one or more of the Serial
and/or Socket Data Transfer Object attributes.
The Assembly object defines the interface by which a Class 1 PLC or controller can:
•
Request the receive data packets from the DeviceMaster EtherNet/IP-Modbus gateway.
•
Write the transmit data to the DeviceMaster EtherNet/IP-Modbus gateway.
