Operands:
D
: Device to be rotated
n
: Number of bits to be rotated in 1 rotation
Explanations:
1. This instruction rotates bit status of the device
D
together with M1970 to the left for
n
bits..
2. The status of the last bit rotated (marked with
※
) is moved to the carry flag M1970.
3. This instruction is generally used in pulse execution mode (RCLP, DRCLP).
4. When RCL is used as 16-bit instruction, Z device cannot be adopted; when RCL is used as 32-bit instruction, V
device cannot be adopted.
5. When specifying the bit device of KnX(Y/M/S), the starting No. should be a multiple of 16 in octal or decimal
format. For example, K1X0, K4Y20 (octal); K1M0, K4S16 (decimal).
6. Valid range of operand
n
: 1 ≤
n
≤ 16 (16-bit), 1 ≤
n
≤ 32 (32-bit)
Program Example:
When X0 goes from OFF to ON, the 16 bits (4 bits as a group) in D10 together with carry flag M1970 (total 17 bits)
will rotate to the left, as shown in the figure below. The bit marked with
※
will be sent to carry flag M1970.
