What the Adapter Does
The 1734-AENT adapter performs the following primary tasks:
• Control of real-time I/O data (also known as implicit messaging) – the
1734-AENT adapter serves as a bridge between POINT I/O modules
and the network
• Support of messaging data for configuration and programming
information (also known as explicit messaging)
Use of the Common
Industrial Protocol (CIP)
The 1734-AENT adapter uses the Common Industrial Protocol (CIP). CIP is
the application layer protocol specified for EtherNet/IP, the Ethernet
Industrial Protocol, as well as for ControlNet and DeviceNet networks. It is a
message-based protocol that implements a relative path to send a message
from the producing device in a system to the consuming devices.
The producing device contains the path information that steers the message
along the proper route to reach its consumers. Since the producing device
holds this information, other devices along the path simply pass this
information; they do not need to store it.
This has the following significant benefits:
• You do not need to configure routing tables in the bridging modules,
which greatly simplifies maintenance and module replacement.
