Move Byte Immediate (Read And Write) - Siemens SIMATIC S7-200 System Manual

Move Byte Immediate (Read and Write)

The Move Byte Immediate instructions allow you to
immediately move a byte between the physical I/O and a
memory location.
The Move Byte Immediate Read (BIR) instruction reads
physical input (IN) and writes the result to the memory
address (OUT), but the process-image register is not
updated.
The Move Byte Immediate Write instruction (BIW) reads the
data from the memory address (IN) and writes to physical
output (OUT), and the corresponding process image
location.
