Read-only Status Bits are outputs from the iVu BCR (inputs to the PLC or HMI). They are used to report the basic status of
the iVu BCR and the last inspection run. This information is available as Input Registers or Holding Registers. Use either
function code 04 (Read Input Registers) or function code 03 (Read Holding Registers). The same data can also be read from
Inputs (10000) using Modbus function code 02 (Read Input Status).

14.6 PLC5, SLC500, and MicroLogix (PCCC)
Allen-Bradley’s PLC5, SLC 500, and MicroLogix family of devices uses PCCC communications protocol.
PCCC is also known as EtherNet/IP transport class 3 and uses explicit Read and Write message commands, or EIP
messaging, placed into the ladder logic program, to interface with the Safety Controller.
These PLCs do not support cyclic EtherNet/IP IO data transfer (referred to as EtherNet/IP in this manual). The programming
software used by these PLCs is RSLogix 5 (PLC5) or RSLogix 500 (SLC500 and MicroLogix series).
The iVu BCR supports these PLCs using input and output register arrays.
The Output bits, ACK bits and Input bits bit definitions are the same as defined in
“Input” and “Output” are from the point of view of the PLC.
