Bit Address is the address of the source bit. The status of this bit is inserted in
either the first (lowest) bit position (BSL) or last (highest) bit position (BSR).
•
Length (size of bit array) is the number of bits in the bit array, up to 1680 bits.
A length value of 0 causes the input bit to be transferred to the UL bit.
A length value that points past the end of the programmed file causes a major
error to occur. If you alter a length value with your ladder program, make
certain that the altered value is valid.
The instruction invalidates all bits beyond the last bit in the array (as defined by
the length) up to the next word boundary.
Effects on Index Register S:24
The shift operation clears the index register S:24 to zero.
