6.13.7 SHRB
Input/output Operand Data type
DATA, S_BIT I, Q, M, SM, T, C, V, S, L Boolean
N VB, IB, QB, MB, SB, SMB, LB, AC,constant, *VD, *LD, *AC Boolean
SHRB instruction moves the DATA value to the shift
register. S_BIT specifies the lowest bit of the shift
register.N specifies the length of the shift register and the
shift direction (shift plus = N, shift minus = -N).The moved
out bit is placed in the overflow memory bit (SM1.1).The
instruction is defined by S_BIT and N.
error conditions:
0006 Indirect address
0091 Operating number is out of range
0092 Count field error
Special memory bit:
SM1.1 Overflow bit
Example:
When the value of M0.0 is 1
，
the value of M10.0 is moved to V0.0
，
the value of V0.0
is moved to V0.1
，
the value of V0.1 is moved to V0.2
，
the value of V0.2 is moved to
V0.3
，
the value of V0.3 is moved to SM1.1.
If N is negative, the shift direction is opposite.
