5/13/23, 6:18 PM *** Strings *** strings S_MOVE The S_MOVE function copies the character string at the IN input ("Set_1") to the tag at the OUT output ("Set_2"). S_CONV Google search on MEINE-SCHALTUNG.de: NE555 NE555 – A microchip is born and has a global career. The S_CONV function is used to convert a string of numbers into a number or a number into a string of numbers. Off delay The secret of the extended signal. CTRL_VAL Impulse switch One impulse - two functions Switch-on delay Why fast when you can do it slowly. Zener diode Zener diode - a diode that is out of line. Frequency converter Reach your goal gently and gently. The STRG_VAL function converts a string of numbers into the corresponding number. The conversion begins at Overview the point entered at input P (4). The result is output at the output OUT ("Result"). With FORMAT (data type Word) you can set the display and decimal point format (bit 1 or 0). circuits overview VAL_STRG The VAL_STRG function converts a number into the corresponding character string. The value at input SIZE (6) determines the number of characters to be written to OUT ("Record_2"). The value at input PREC (2) refers to the decimal places. The replacement of the characters in the character string OUT begins at the position that is entered at input P (7). The result is output at the output OUT. With FORMAT (data type Word) you can set the sign, representation and decimal point format (bit 2, 1 or 0). https://www.meine-schaltung.de/themen/sps/zeichenketten/ 1/5 5/13/23, 6:18 PM *** Strings *** Ctrl_TO_Chars perpetual calendar The Strg_TO_Chars function copies the character string specified at the Strg ("Satz_1") input into an array of characters. Target array is specified at IN/OUT terminal Chars ("Var.CharacterArray"). The function overwrites the characters from the position entered at the pChars (1) input. The number of characters copied is output at the output Cnt ("Cnt"). Var.CharArray (Array [0..24 of Char] before conversion: [x][x][x][x][x][x][x][x][x][x][x][x][x][x][x][x][x ][x][x][x][x][x][x][x][x] After conversion: [x][M][e][i][n][ ][e][ r][s][t][e][r][ ][S][a][t][z][x][x][x][x][x][x][x][ x] Chars_TO_Ctrl The Chars_TO_Strg function copies elements of an array of characters into a character string. The array of characters is declared at the Chars input ("VAR.CharacterArray"). The number of characters to be copied is entered at input Cnt (16). Start character is declared at input pChars (1). The previously declared character string is entered at the Ctrl ("Record_2") output. Var.CharacterArray = [x][M][e][i][n][ ][e][r][s][t][e][r][ ][S][a][t] [z][x][x][x][x][x][x][x][x] Set_2 before conversion: ' ' Set_2 after conversion: 'My first set' MAX_LEN The MAX_LEN function determines the maximum length of the character string specified at input IN ("Record_1"). The result is output at the output OUT ("Result"). https://www.meine-schaltung.de/themen/sps/zeichenketten/ 2/5 5/13/23, 6:18 PM *** Strings *** LEN The LEN function determines the current length of a character string that was entered at input IN ("Record_1"). The result is output at the output OUT ("Result"). CONCAT The CONCAT function combines two character strings. LEFT The LEFT function forms a partial character string from the character string entered at input IN ("Record_1") and outputs it at output OUT ("Record"). The substring consists of the first L (4) characters of the original string. RIGHT The RIGHT function forms a partial character string from the character string entered at input IN ("Sentence_1") and outputs it at output OUT ("Sentence"). The substring consists of the last L (3) characters of the original string. MID The MID function forms a partial character string from the character string entered at input IN ("Record_1") and outputs it at output OUT ("Record"). The substring consists of L(3) characters of the original string and starts at the character position input at input P(2). DELETE https://www.meine-schaltung.de/themen/sps/zeichenketten/ 3/5 5/13/23, 6:18 PM *** Strings *** The DELETE (delete) function deletes L (4) characters from character position P (1) from the character string that is input at input IN ("block_1"). The result is output at the output OUT ("block"). INSERT The INSERT function inserts the character string entered at input IN1 ("block_2") into the character string entered at input IN2 ("block_3"). Insertion begins after character position P(4). The result is output at the output OUT ("block"). REPLACE The REPLACE function replaces L (9) characters in the character string entered at input IN1 ("Record_1") with the character string entered at input IN2 ("Record_2"). The replacement starts at character position P(1). The result is output at the output OUT ("block"). FIND The FIND (find) function returns the position of the character string entered at input IN2 ("block_2") in the character string entered at input IN1 ("block_1"). The result is output at the output OUT ("Result").
