Tc2_Utilities¶

Compatibility library for Beckhoff’s TwinCAT 3 Tc2_Utilities PLC library: utility and formatting functions. Activated by a project reference or --library Tc2_Utilities.

Functions¶

Name	Signature	Description
`LREAL_TO_FMTSTR`	`LREAL_TO_FMTSTR(in : LREAL, iPrecision : INT, bRound : BOOL) : STRING`	Formats in as a fixed-point decimal string with iPrecision digits after the decimal point (clamped to 0..15). When bRound is `TRUE` the last place is rounded (half away from zero); when `FALSE` it is truncated toward zero. Values that cannot be rendered (NaN, infinities, magnitudes of 2⁶³ or more) return an empty string.

The formal parameter names (in, iPrecision, bRound) match the vendor’s documented names.

Example¶

text := LREAL_TO_FMTSTR(in := 3.14159, iPrecision := 2, bRound := TRUE);
(* text = '3.14' *)

Independence¶

IronPLC is an independent open-source project and is not affiliated with, endorsed by, or sponsored by the vendors whose library interfaces the compatibility libraries reproduce. Each compatibility library is authored independently from the vendor’s public documentation and contains no vendor code. See Trademarks.
