32-bit data (double word data)
Data size and data range
32-bit data includes signed and unsigned 32-bit data.
In signed 32-bit data, a negative number is represented in two's complement.
Handling 32-bit data with bit devices
A bit device can be handled as 32-bit data by performing digit specification.
A bit device used in safety programs executed by the Safety CPU can be handled as 32-bit data by performing digit
specification.
Handling 32-bit data with bit type array labels
A bit type array label can be handled as 32-bit data by performing digit specification.
The following table shows the notation for handling a bit type array label as 32-bit data by digit specification.
