WriteNbit_**
The following example shows the WriteNbit_BYTE instruction when In is BYTE#16#89, Pos is USINT#2
and Size is USINT#4.
Use a ReadNbit_** instruction to read zero or more bits from a bit string.
• The data types of In and InOut must be the same.
• The value of InOut does not change if the value of Size is 0.
• Return value Out is not used when the instruction is used in ST.
• An error occurs in the following cases. ENO will be FALSE, and InOut will not change.
• The value of Size is outside of the valid range.
• The value of Pos is outside of the valid range.
• The bit string in InOut does not have enough bits for the number of bits specified by Size from the
position specified by Pos.
