Function
The higher and lower bytes of the variable in S are exchanged.
In 16-bit operation, the higher eight bits and the lower eight bits are exchanged.
In 32-bit operation, the higher eight bits and the lower eight bits of two registers are exchanged.
The instruction of the pulse execution type is generally used. If the continuous execution type is used,
calculation is performed on every program scan.

In the figure on the left, the values of higher and lower
eight bits in D20 are exchanged.
In the figure on the right, the values of higher and lower
eight bits in D20 are exchanged, and the values of higher
and lower eight bits in D21 are exchanged.
BON: ON bit check

Overview
When driving conditions are met, the BON instruction checks the status of the Kth bit of the binary data in S.
The result is used for D status control.
