6.1.8 Set immediate and reset immediate
Input / output
Operand
Data type
Bit Q Boolean
N VB, IB, QB, MB, SMB, SB, LB, AC, constant, *VD, *AC, *LD Byte
“ Set immediate ” can set many of points immediately.
“ Reset immediate ” can reset many of points immediately.
The value of N is between 1 and 128.
"I" means"reference immediately"
；
The new value generated by
executing the instruction is written to the actual output and the
corresponding process image register.
6.1.9 SR instruction
Input / output
Operand
Data type
S1, R (LAD) Enable bit Boolean
S1, R (FBD) I, Q, M, SM, T, C, V, S, L, Enable bit Boolean
OUT (LAD) Enable bit Boolean
OUT (FBD) I, Q, M, SM, T, C, V, S, L, Enable bit Boolean
xxx I, Q, M, V, S Boolean
Bistable trigger is a latch.When both R and S1 are equal to 1, the
output is 1.
The truth table of the "SR" instruction is as follows:
Instruction S1 R OUT
SR 0 0 Previous state
0 1 0
1 0 1
1 1 1
