Function Explanation

DegToRad is used to convert the input parameter In to a radian and the result is output to Out. That
is, Out =( In/180)* π.

The units of In and Out are degree (°) and radian respectively.

Users can choose different data types for the input parameter in this instruction. But the data type of
the output parameter is restricted to LREAL. An error will occur during the compiling of the software
if the data type of the output parameter is not LREAL.

Precautions for Correct Use

The input variables are not allowed to omit. An error will occur during the compiling of the software if
the input variable is omitted. But the output variables are allowed to omit.

Programming Example

The data types of DegToRad _In and Out1 are INT and LREAL respectively. The value of Out1 is
0.174532925199433 if the value of DegToRad _In is 10 when DegToRad _EN changes to TRUE.
The value of Out1 is -0.174532925199433 as DegToRad _In is -10.
