Operator: EXPT The IEC operator raises a number to a higher power and returns the power of the base raised to the exponent: power = base exponent . The input values (parameters) are the base and the e

Operator: SIN The IEC operator yields the sine 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 outpu

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: __POSITION The operator is an extension of the IEC 61131-1 standard. At runtime, the operator yields the position of a variable in the declaration part or in the implementation part of a POU

Variable: VAR_INST The VAR_INST instance variables are allowed only in methods. This kind of variable can be accessed only within the method. You can monitor the variable values of instance variables

Variable: VAR_CONFIG Configuration variables assign the full address to variables which are declared in function blocks with incomplete address information and that should be mapped to device I/Os. Th
