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 (Only the CCCP is supported) 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.
SettingsoftheRecorder
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, which is also called DF1 communication, is a serial communication protocol 
specific to Rockwell Automation PLCs.
The recorder supports EtherNet/IP in which PCCC requests are encapsulated. It can 
communicate also with PLCs that support encapsulated PCCC.
Communication using Explicit messages are only supported for PCCC.
