1.2
Data Specification Method
The following table lists the types of data that can be used for instructions in CPU modules.
Device data
*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.
Data type
Description
Specifiable device/constant
Bit
Bit data can be handled.
• Bit device
