Connection Properties: Class 3 Explicit Messaging

All Class 1 I/O assembly data and additional data are accessible via Explicit message. Input data
(camera to PLC/Client) occupies attributes 1 to 100 of the classes. Output data (PLC/Client to camera)
occupies attributes 101 to 200.
 Service:
• Get Attibute Single (0xE)
• Set Attibute Single (0x10)
 Class:
• bool = 104 (0x68)
• int = 105 (0x69)
• long = 106 (0x6A)
• float = 107 (0x6B)
• string = 108 (0x6C)
• Conttol/Status (mixed data type) = 109 (0x6D)
 Instance:
• 1
 Attribute:
• 1 to 100 = In to PLC/Client
• 101 to 200 = Out to Smart Camera
 Attribute Layout
When using explicit EtherNet/IP messaging, all global data objects can be read or written.
Each data type is stored in its own class object and an instance of 1 to read the global data. For
example, to read float2, the EtherNet/IP request would be for Service Code 14 (0xE), Class 107
(0x6B), Instance 1, Attribute 2.
