Banner iVu Plus BCR Gen2 Series - Input and Output Flags Bits; Configuration Assembly Object; Data Formats; Minimum Requested Packet Interval (RPI) Value

14.4.3 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 BCR device to the PLC. The 32 bits of iVu BCR 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)).

14.4.4 Configuration Assembly Object
The iVu BCR 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
®
11
family PLC. Therefore, a configuration instance
is defined as instance number 128 (0×80). Its size is zero.
14.4.5 Data Formats
The iVu BCR 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 BCR:
Word
0 1 2 3 4
Length
LSW
Length
MSW
byte 1 byte 0 byte 3 byte 2 byte 5 byte 4 ... ...
14.4.6 Minimum Requested Packet Interval (RPI) Value
The iVu BCR 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.
