Operands:

S: Start No. of source device D: Start No. of destination device n

: Length of data to be

shifted n

: Number of devices to be shifted as a group

Explanations:

1. This instruction performs a right shift from source device of n

registers starting from S to

destination device of n

registers starting from D.

2. This instruction is generally used in pulse execution mode (WSFRP).

3. The type of devices designated by S and D has to be the same, e.g. K

X, K

Y, K

M, and K

as a category and T, C, and D as another category

4. Provided the devices designated by S and D belong to K

type, the number of digits of K

in S

and D has to be the same.

5. Valid range of operand n1, n2 : 1≤ n2 ≤ n1 ≤512

Program Example 1:

1. When X0 is triggered, WSFRP instruction shifts D10~D13 into data stack D20~D35 and

D20~D35 also shift to the right with a group of 4 registers.

2. The figure below illustrates the right shift of the registers in one scan.

n D23~D20 → Carry

o D27~D24 → D23~D20

p D31~D28 → D27~D24

q D35~D32 → D31~D28

r D13 ~D10 → D35~D32 completed
