How do you convert degrees into radians and vice versa in STEP 7 Basic V10.5?
Instructions For processing the trigonometric functions sine, cosine and tangent with STEP 7 Basic V10.5, you must specify the angle in radians (0 to 2π) as floating point number. The angle must be available in ACCU 1 as a floating point number. The result is stored again in ACCU 1. The angles are usually given in degrees (0 to 360 degrees). In order to be able to process these values with STEP 7, you must convert these degree values into radian values. Both values are proportional to each other; the value 180 degrees corresponds to the number π (3.141593…). • Radian value = degree value * π / 180 • Degree value = radian value * 180 / π Fig. 01 The STEP 7 Basic project includes the “Angle” function (FC1) that you can use to convert from degrees to radians and vice versa. • Conversion of the angle from degrees to radians • Input parameter: “E_Angular” with the data type: REAL • Output parameter: “A_Radian” with the data type: REAL Conversion of the angle from radians to degrees • Inpu
