Allen-Bradley MicroLogix 1100 Instruction Set Reference Manual

Publication 1763-RM001C-EN-P - October 2009
File Instructions 227
If you wish to shift more than one bit per scan, you must create a loop in
your application using the JMP, LBL, and CTU instructions.
This instruction uses the following operands:
• File - The file operand is the address of the bit array that is to be
manipulated.
• Control - The control operand is the address of the BSL’s control
element. The control element consists of 3 words:
• Bit Address - The source is the address of the bit to be transferred
into the bit array at the first (lowest) bit position.
• Length - The length operand contains the length of the bit array in
bits. The valid data range for length is from 0 to 2048.
Addressing Modes and File Types can be used as shown in the following
table:

EN
(1)
(1) EN - Enable Bit is set on false-to-true transition of the rung and indicates the instruction is enabled.
--
DN
(2)
(2) DN - Done Bit, when set, indicates that the bit array has shifted one position.
--
ER
(3)
(3) ER - Error Bit, when set, indicates that the instruction detected an error such as entering a negative number for the
length or source operand.
UL
(4)
(4) UL - Unload Bit is the instruction’s output. Avoid using the UL (unload) bit when the ER (error) bit is set.
