Dint to bool
WebJan 13, 2024 · The bit pattern corresponding to 65535 (16 1s in a row) will be interpreted as "-1" if the PLC is expecting a signed integer instead of unsigned. Unsigned: 1111 1111 1111 1111 = 65535. Signed: 1111 1111 1111 1111 = -1. A DINT is 32 bits, so a signed DINT can range from -2147483648 to 2147483647. WebApr 8, 2024 · The conversion of a 16-bit value to 16 individual bits uses the AND logical operator in a script. In WinCC (TIA Portal) you would need to use a script that takes the int value and mask each bit with a logical AND to 1, which would give you the status of one particular bit, the lowest (first). You must then repeat the same int AND 2 to examine ...
