SIN(P)
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
an error code is stored into SD0.
• The value of the specified device is
(For the Basic model QCPU, High Performance model QCPU, Process CPU, Redundant
CPU)
*2: There are CPU modules that will not result in an operation error if
• The result exceeds the following range (Operation results in an overflow)
(For the Universal model QCPU, LCPU)

• The value of the specified device is
(For the Universal model QCPU, LCPU)
Program Example
(1) The following program conducts a SIN operation on the angles stored in the four BCD digits
from X20 to X2F and stores the results at D0 and D1 as 32-bit floating decimal point type
real numbers.
