PUTBIT (FUN) ¶ FUNCTION PUTBIT : DWORD Sets a bit of a DWORD value Example in ST: var1 := 38 ; (* binär 100110 *) var2 := PUTBIT ( A , 4 , TRUE ); (* Result: 54 = 2#110110 *) var3 := PUTBIT ( A , 1 , FALSE ); (* Result: 36 = 2#100100 *) InOut: Scope Name Type Comment Return PUTBIT DWORD Value with the changed bit Input X DWORD Value to be manipulated N BYTE Position of the bit to be changed, starting with 0 B BOOL Value of specified bit

SETBIT (FUN) ¶ FUNCTION SETBIT : BOOL Sets the value of bit at position N of variable X to B InOut: Scope Name Type Comment Return SETBIT BOOL Input X __SYSTEM.AnyType Variable to be modified N BYTE Bitnummer 0…(to size of datatype) B BOOL Desired value of the bit

BCD Conversions ¶ A BYTE in the BCD format contains integers between 0 and 99. Four BITs are used for each decimal place. The ten decimal place is stored in the BITs 4-7. Thus the BCD format is similar to the hexadecimal presentation, with the simple difference that only values between 0 and 99 can be stored in a BCD BYTE, whereas a hexadecimal BYTE reaches from 0 to FF. Example: The integer 51 should be converted to BCD format: 5 in binary code is 0101, 1 in binary code is 0001, which makes the BYTE 01010001 in BCD code, which corresponds to the value $51=81.
