Mitsubishi MELSEC-Q/L

522
DEG, DEGP
Program Example
(1) The following program converts the angle set by the 4 BCD digits at X20 to X2F to radians, and stores results as 64-bit
floating decimal point type real number at D20 to D23.
[Ladder Mode]
[List Mode]
[Operations involved when X20 to X2F designate a value of 120]
: 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)
*1: Applicable for the Universal model QCPU, LCPU.
Function
(1) Converts units of angle size from radian units designated by to angles, and stores result at device number designated
by .
(2) The conversion from radians to angles is performed according to the following equation:
7.12.15 DEG, DEGP Conversion from floating-point radian to angle
(Single precisio n)
7.12.15 DEG, DEGP
• Basic model QCPU: The serial number (first five digits) is
"04122" or later.
