Introduction of Features
What the Recorder Can Do
The recorder provides the following functions:
• Participate in an EtherNet/IP network as an Adapter (Server).
• Communicate with new and old Allen-Bradley PLCs such as MicroLogix, CompactLogix,
ControlLogix, SLC 500, PLC-5, and PLC-2.
• Support both Explicit and I/O messages.
• PLCs can access internal data of the recorder.

The following shows examples of usage.
• Data on devices on a network can be recorded by a PLC to the recorder.
• Data measured by the recorder can be acquired by a PLC.
Settings of the Recorder
The recorder is ready to use after the following settings have been made.
• IP address and other settings required to connect to Ethernet
• Enabling of EtherNet/IP server function
Access to the Recorder
The recorder is a passive device on an Ethernet network. The recorder cannot launch a
request. A PLC launches a request to the recorder.
A request is called a “message”. There are two message types: Explicit message and I/O
messages (Implicit message). An Explicit message, included in control logic, is used to
access the recorder, only when required, and transmit data. An I/O message is used to
transmit pre-specified recorder data at intervals.
The Recorder can also communicate with PLCs compatible with Programmable Controller
Communication Command (PCCC) using conversion of PCCC to EtherNet/IP at the
gateway. PCCC refers to serial communications that are also called DF1 communications.
The recorder supports EtherNet/IP in which PCCC requests are encapsulated. It can
communicate also with PLCs that support encapsulated PCCC.
