REPLACE (FUN) ¶ FUNCTION REPLACE : STRING(255) Replaces a specific number of characters of a string by another string REPLACE(STR1, STR2, L, P) means: Replace L characters from STR1 by STR2 , beginning with the character in the P position. POS = 0 or POS = 1 , are both addressing the first character. Note The current implementation is unfortunately not correct for the case P=0 . The implementation cannot be changed for compatibility reasons. If P=0 is used, the parameter L is internally reduced by one! It is generally recommended to use values in the range specified by IEC 61131-3. The smallest value for P is specified there as 1 . (* Example declaration *) VarSTRING1 : STRING ; (* Example in ST , result is 'SKYSI' *) VarSTRING1 := REPLACE ( 'SUXYSI' , 'K' , 2 , 2 ); InOut: Scope Name Type Comment Return REPLACE STRING(255) Resulting string Input STR1 STRING(255) String of which a part is replaced STR2 STRING(255) String which replaces a part of STR1 L INT Number of characters, counting from left P INT Start position of the characters to be replaced. P = 1 or P = 0 are both addressing the first character
RIGHT (FUN) ¶ FUNCTION RIGHT : STRING(255) Returns a specific number of characters of a string, starting from right RIGHT (STR, SIZE) means: Return the first SIZE characters from the right in string STR (* Example declaration *) VarSTRING1 : STRING ; (* Example in ST , result is 'USI' *) VarSTRING1 := RIGHT ( 'SUSI' , 3 ); InOut: Scope Name Type Comment Return RIGHT STRING(255) Resulting string Input STR STRING(255) String to be analyzed SIZE INT Number of characters
Timer ¶ TOF (FunctionBlock) TON (FunctionBlock) TP (FunctionBlock)
TOF (FB) ¶ FUNCTION_BLOCK TOF Implements a timer with a turn-off delay (* Example declaration *) TOFInst : TOF ; (* Example in ST *) TOFInst ( IN := VarBOOL1 , PT := T#5s ); VarBOOL2 := TOFInst.Q ; InOut: Scope Name Type Comment Input IN BOOL Falling edge: starts delay counter Rising edge: resets delay counter PT TIME Time for the delay counter [ms] Output Q BOOL TRUE if IN is TRUE FALSE if IN is FALSE and delay time PT elapsed ET TIME Elapsed time since falling edge at IN
TON (FB) ¶ FUNCTION_BLOCK TON Implements a timer with a turn-on delay (* Example declaration *) TONInst : TON ; (* Example in ST *) TONInst ( IN := VarBOOL1 , PT := T#5s ); VarBOOL2 := TONInst.Q ; InOut: Scope Name Type Comment Input IN BOOL Rising edge: starts delay counter Falling edge: resets delay counter PT TIME Time for the delay counter [ms] Output Q BOOL FALSE if IN is FALSE TRUE if IN is TRUE and delay time PT elapsed ET TIME Elapsed time since rising edge at IN
TP (FB) ¶ FUNCTION_BLOCK TP Implements a pulse timer (* Example declaration *) TPInst : TP ; (* Example in ST *) TPInst ( IN := VarBOOL1 , PT := T#5s ); VarBOOL2 := TPInst.Q ; InOut: Scope Name Type Comment Input IN BOOL Rising edge starts the pulse timer and sets Q to TRUE PT TIME Length of the pulse (high-signal) Output Q BOOL Pulse signal, set to TRUE for PT milliseconds if EN has a rising edge ET TIME Elapsed time since pulse timer started. It will then remain constant after PT is reached.
