EtherNet/IP Connections andData Mapping

Topic: PAL016

The PAL EtherNet/IP interface supports EtherNet/IP in the following methods:

Class 1 I/O Messaging (also called “Implicit Messaging”)
Class 3 Explicit Messaging
Unconnected Explicit Messaging

Class 1 I/O Messaging

Input Connection Point = 101 (0x65)
Input Data Size = 146 bytes
Output Connection Point = 100 (0x64)
Output Data Size = 102 bytes
Configuration Connection Point = 3
Configuration Data Size = 0
Run/Idle header should be enabled
Supports Unicast or Multicast for Input (T->O) data.

Class 3 Explicit or Unconnected Explicit

Input Data:
- Service = Get Single Attribute = 14 (0x0E)
- Class = 4
- Instance = 101 (0x65)
- Attribute = 3
- Size = 146 bytes
Output Data:
- Service = Set Single Attribute = 16 (0x10)
- Class = 4
- Instance = 100 (0x64)
- Attribute = 3
- Size = 102 bytes
