Conversion Operations for IEC

Convert to Boolean Boolean- [Data Type BOOL] - A single bit, binary value, or register/variable. Boolean points have only two possible values, 'TRUE' or 'FALSE'.

Any to Bool

Operator - Converts the input into Boolean value.

Inputs

IN : ANY Input value

Outputs

Q : BOOL Value converted to Boolean

Remarks - For DINT Double Integer - [Data Type DINT] - A 32-bit signed value. Double Integers are used where the value of the data is expected to be in the range of -2,147,483,648 to +2,147,483,647., REAL These numbers use IEEE 754-1985 format to store numbers in following ranges. 32-bit single-precision floating point (REAL) – -3.40282E+38 to +3.40282E+38 64-bit double-precision floating point (LREAL) – -1.79769E+308 to +1.7976E+308 Floating Point refers to both REAL and LREAL data types. and TIME TIME: Time of day - Time constant expressions represent durations that must be less than 24 hours. Expressions must be prefixed by either "TIME#" or "T#". They are expressed as a number of hours followed by "h", a number of minutes followed by "m", a number of seconds followed by "s", and a number of milliseconds followed by "ms". The order of units (hour, minutes, seconds, milliseconds) must be respected. The user cannot insert blank characters in the time expression. There must be at least one valid unit letter in the expression. input data types, the result is FALSE if the input is 0. The result is TRUE in all other cases. For STRING inputs, the output is TRUE if the input string is not empty, and FALSE if the string is empty. In LD language, the conversion is executed only if the input rung (EN) is TRUE. The output rung is the result of the conversion. In IL Language, the ANY_TO_BOOL function converts the current result.

ST Language

Q := ANY_TO_BOOL (IN) ;

LD Language

(* The conversion is executed only if EN is TRUE *)

Convert to REAL

Any To REAL REAL: Single precision floating point value - Real constant expressions must be valid number, and must include a dot ("."). If the user needs to enter a real expression having an integer value, add ".0" at the end of the number. The user can use "F" or "E" separators for specifying the exponent in case of a scientist representation. REAL is the default precision for floating points: such expressions do not need any prefix.

Operator - Converts the input into real value

They are expressed as a number of hours followed by "h", a number of minutes followed by "m", a number of seconds followed by "s", and a number of milliseconds followed by "ms". The order of units (hour, minutes, seconds, milliseconds) must be respected. The user cannot insert blank characters in the time expression. There must be at least one valid unit letter in the expression.
