ETHERNET/IP™. The EtherMeter provides elementary support for EtherNet/IP™, an
industrial communication protocol for Ethernet. EtherNet/IP™ was originally developed by
Rockwell Automation and is now managed by ODVA. This manual assumes that the user is well-
versed in the EtherNet/IP™ Protocol. In order to learn more about this protocol, please visit
rockwellautomation.com or odva.org. The following document is a particularly useful reference
for EtherNet/IP™ communications with Rockwell Automation PLC’s:
“Communicating With Rockwell Automation Products Using EtherNet/IP Explicit Messaging”
http://www.rockwellautomation.com/enabled/pdf/eipexp1_2.pdf
The EtherMeter implements a functional subset of the EtherNet/IP™ Protocol:
• “Unconnected Explicit Messaging with Encapsulation of PCCC”
• “Class 3 Connected Explicit Messaging with Encapsulation of PCCC”.
The EtherMeter responds to messages that utilize the following Service Request Codes:
• “Execute PCCC Service” (Code 0x4B)
• “VDH+ Service” (Code 0x4C)
• “Local Service” (Code 0x4D)
Please note that CIP™ and data subscriber/provider mechanisms are not supported; and
fragmented EtherNet/IP™ packets are also not supported.
The EtherNet/IP™ server is available on TCP logical port 44818 of the EtherMeter, although the
user may specify an alternate port through the Setup Menu.
