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 0.

(For the Basic model QCPU, High Performance model QCPU, Process CPU, Redundant
CPU) (Error code: 4100)
*2: There are CPU modules that will not result in an operation error if 0 is specified. For details, refer to 3.2.4.

Program Example
(1) The following program converts the radian value set with 32-bit floating decimal point type
real number at D20 and D21 to angles, and stores the result as a BCD value at Y40 to Y4F.
