1 OVERVIEW
1.2 Data Specification Method
16-bit data (word data)
Data size and data range
16-bit data includes signed and unsigned 16-bit data.
In signed 16-bit data, a negative number is represented in two's complement.
Handling 16-bit data with bit devices
A bit device can be handled as 16-bit data by performing digit specification.
A bit device used in safety programs executed by the Safety CPU can be handled as 16-bit data by performing digit
specification.
Handling 16-bit data with bit type array labels
A bit type array label can be handled as 16-bit data by performing digit specification.
The following table shows the notation for handling a bit type array label as 16-bit data by digit specification.
Data name
Data size
Value range
Decimal notation
Hexadecimal notation
Signed 16-bit data
16 bits (1 word)
-32768 to 32767
0000H to FFFFH
Unsigned 16-bit data
0 to 65535
