Functions Not Present in Control Expert

DFB Wrapper

Functions from Concept that are not present in Control Expert get a DFB wrapper if they are called in ST sections (e.g., WORD_AS_UDINT). For example:

WAUD(* UDINT *) := WORD_AS_UDINT (LOW := WAUL, (* WORD *) HIGH := WAUH(* WORD *));

. . . looks like this after conversion:

WAUD(* UDINT *) := FBI_ST1_75_33 (LOW := WAUL, (* WORD *)HIGH := WAUH(* WORD *));

Manual Correction

FBI_ST1_75_33 is the instance name of the provided DFB wrapper. However, the call is still invalid for the analyzer because the converter cannot yet do multi-object syntax corrections in ST. (Will be present in V2.0).

You must correct this manually to:

FBI_ST1_75_33 (LOW := WAUL, (* WORD *) HIGH := WAUH(* WORD *), OUT => WAUD);
