Host Command Reference
Appendix H: EtherNet/IP
EtherNet/IP products, designated by the letters “IP” in the model number, provide access to Q and SCL
functionality over EtherNet/IP networks. This appendix details which commands are available and how to
encapsulate them into EtherNet/IP and CIP packets. It is assumed that the user has a working knowledge
of EtherNet/IP as it relates to the controller being used, as this chapter will not explain general EtherNet/IP
implementation details.
AMP offers both Class 1 and Class 3 type connections, each of which are useful for specific tasks. Class 1
connections are useful for high bandwidth tasks such as monitoring specific functions of the drive, while Class 3
connections are used for sending targeted messages to directly control the drive. The latter is used to implement
Explicit Messaging.
Note that with EtherNet/IP, all data direction notation assumes the point of view of the network. In this way,
data sent by the drive to the controller is referred to as an Input, while data sent by the controller down to the drive
is referred to as an Output.
The Class 1 Connection
Class 1 connections use Connection Points, which can be thought of as addresses with predefined
functions. To communicate with an Applied Motion drive using a Class 1 connection, the following connection
points are available.
Object ID Function Notes
Hex Decimal
0x64 100 Input Assembly Static Assembly Object for monitoring drive status &
behavior (see below for details)
0x66 102 Configuration Assembly Specifies parameters such as packet interval, data
length.
0x67 103 Heartbeat Input Only Assembly Zero-length message that tells the controller the
drive is still active.
0x68 104 Heartbeat Listen Only Assembly Zero-length message that tells the drive the
controller is still active.
