Mitsubishi Electric MELSEC iQ-R Series - 16-Bit Data (Word Data)

42
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
