Data Specification Method

The following table lists the types of data that can be used for instructions.
Data
Bit data
16-bit data (word data)
32-bit data (double word data)
Real number data (floating-point data)
Character string data
Device data
The following table lists devices and constants that can be used to specify the setting data of instructions.
Data type Description
Bit Bit data can be handled.
Word Word data can be handled.
16-bit signed binary 16-bit data can be handled.
The value range varies depending on whether the value is signed or unsigned.
16-bit unsigned binary
Double word Double-word data can be handled.
32-bit signed binary Two consecutive sets of 32-bit data or 16-bit data can be handled.
The value range varies depending on whether the value is signed or unsigned.
32-bit unsigned binary
Single-precision real Single-precision real number data (single-precision floating-point data) can be
number handled.
Double-precision real Double-precision real number data (double-precision floating-point data) can
number be handled.
Character string ASCII code and Shift JIS code character string data can be handled.
Character string [Unicode] Unicode character string data can be handled.
Device name A device can be specified directly.
*1 A constant can be used in the data specified for the source (s) or numerical data (n) by an instruction.
*2 For the specification method, refer to the detail page of each data type.
