Operator: COS The IEC operator yields the cosine value of a number. Permitted data types for input variables that measure the angle in radians: any numeric basic data type Permitted data types for out

Operator: TAN The IEC operator yields the tangent value of a number. Permitted data types for input variables that measure the angle in radians: any numeric basic data type Permitted data types for ou

Operator: ASIN The IEC operator yields the arcsine value of a number. Permitted data types for input variables: any numeric basic data type Permitted data types for output variables: REAL and LREAL Ex

Operator: ACOS The IEC operator yields the arccosine value of a number. The value is computed in radians. Permitted data types for input variables that measure the angle in radians: any numeric basic

Operator: ATAN The IEC operator yields the arctangent value of a number. The value is computed in radians. Permitted data types for input variables that measure the angle in radians: any numeric basic

Operator: __DELETE The operator is an extension of the IEC 61131-3 standard. Important For compatibility, the compiler version must be >= 3.3.2.0. The operator releases the memory of instances that th

Operator: __ISVALIDREF The operator is an extension of the IEC 61131-3 standard. The operator is used for checking whether a reference refers to a valid value. For a description of use and an example,

Operator: __NEW The operator is an extension of the IEC 61131-3 standard. The __NEW operator reserves dynamic memory to instantiate function blocks, user-defined data types, or arrays of standard type
