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.
*2: There are CPU modules that will not result in an operation error if -0 is specified.
For details, refer to Page 88, Section 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.
[Ladder Mode]
[List Mode]
[Operations involved when the values at D20 and D21 are 1.435792]
: Radian angle to be converted to degrees or head number of the devices where the radian angle is stored (real number)
: Head number of the devices where the value converted in degrees will be stored (real number)
