Bit Shift Left and Right in Ladder Logic

17.5k

The BSL instruction is a rung output ladder logic instruction that shifts data in an array one bit to the left every time it is executed. The source bit's value is loaded into the array's lowest bit by this instruction. The unload bit is determined by the length.

The BSL command loads data one bit at a time into a bit array. The data is shifted across the array one bit at a time before being discharged. This command could be used, for example, to track bottles through a bottling process where each bottle represents a bit. The BSL command is a command that allows you to communicate in sign language.

  • Equal.
  • Not Equal.
  • One Greater Than the other.
  • One Greater Than or Equal To the other.
  • One Less Than the other.
  • One Less Than or Equal To the other.

In Ladder Logic, a bit shift left is when the bit position moves to the left. A bit shift right is when the bit position moves to the right. A left shift of one is equivalent to multiplying by two and a right shift of one is equivalent to dividing by two.

The binary representation of a number is made up of two bits. When one bit is shifted to the left, it becomes 0 and when it is shifted to the right, it becomes 1. The result of a shift in either direction will always be positive or negative depending on whether the original number was positive or negative.
