Boolean Operand Description
FCMP S1, S2 (S1+1, S1) > (S2+1, S2) → R900A: on
(S1+1, S1) = (S2+1, S2) → R900B: on
(S1+1, S1) < (S2+1, S2) → R900C: on
FWIN S1, S2, S3 (S1+1, S1) > (S3+1, S3) → R900A: on
(S2+1, S2)
(S1+1, S1) < (S2+1, S2) → R900C: on
When (S1+1, S1) > (S3+1, S3), (S1+1, S1) → (D+1, D)
FLIMT S1, S2,
S3, D
When (S2+1, S2) < (S3+1, S3), (S2+1, S2) → (D+1, D)
When (S1+1, S1)
FBAND S1, S2, When (S1+1, S1) > (S3+1, S3),
S3, D
When (S2+1, S2) < (S3+1, S3),
When (S1+1, S1)
FZONE S1, S2, When (S3+1, S3) < 0.0,
S3, D
When (S3+1, S3) = 0.0, 0.0 → (D+1, D)
When (S3+1, S3) > 0.0,
S PID processing is performed depending on the control
value (mode and parameter) specified by (S to S+2)
and (S+4 to S+10), and the result is stored in the
(S+3).
DTR S, D If the data in the 16-bit area specified by "S" has
changed since the previous execution, internal relay
R9009 (carry flag) will turn on. "D" is used to store the
data of the previous execution.
DDTR S, D If the data in the 32-bit area specified by (S+1, S) has
changed since the previous execution, internal relay
R9009 (carry flag) will turn on.
(D+1, D) is used to store the data of the previous exe-
cution.
(S1+1, S1) (S3+1,S3) → R900B: on
(S3+1, S3)
(S3+1, S3) → (D+1, D)
(S3+1, S3) - (S1+1, S1) → (D+1, D)
(S3+1, S3) - (S2+1, S2) → (D+1, D)
(S3+1, S3)
0.0 → (D+1, D)
(S3+1, S3) + (S1+1, S1) → (D+1, D)
(S3+1, S3) + (S2+1, S2) → (D+1, D)
