iVu Plus TG and Color Gen2 Image Sensors
In this example, there are only two Blemish sensors in the current inspection. The Blemish3 location will be all zero on the
customizable space. The customizable map had not reserved space for a Match sensor, so Match1 from the inspection will
not be outputted on the custom map.
15.4.4 Input and Output Flags Bits
The Input Bits are used to command execution of basic functions. The Output Bits are used to push single bit outputs from
the iVu device to the PLC. The 32 bits of iVu output can also be accessed using the bits of the first two Output Registers
(Input Bits ACK Register(word 0) and Output Bits Register (word1)).

15.4.5 Configuration Assembly Object
The iVu EtherNet/IP implementation does not support an assembly object Configuration instance. However, one is required
for the creation of implicit Class 1 connections on a ControlLogix
defined as instance number 128 (0×80). Its size is zero.
15.4.6 Data Formats
The iVu EtherNet/IP implementation supports 32-bit Integers in LSW_MSW data format. The LSW_MSW data format is such
that the least significant word is stored first, then the most significant word. This format is used for Allen-Bradley
ControlLogix PLCs.
The string format is compatible with the Allen-Bradley ControlLogix built-in string data type. This format is a 32-bit (DINT)
length followed by character bytes (SINT). This results in the following string format as viewed from the iVu:
0
Word

15.4.7 Minimum Requested Packet Interval (RPI) Value
The iVu can operate with input and output Requested Packet Intervals (RPIs) as low as 50 milliseconds. The device may not
operate reliably if a lower RPI value is selected.
