Instruction Format

(3)Source (S)

The source contains the data to be used for operation. The data changes depending on the specified device.

Constant

Specify the numerical value to be used for

 

 

operation. Since this value is set at the time of

 

 

program creation, it is fixed and cannot be

 

 

changed during program execution.

Bit device

Specify the device that stores the data to be

 

Word device

used for operation. Therefore, the data must

 

 

have been stored into the specified device until

 

 

operation is executed. By changing the data

 

 

stored into the specified device during program

 

 

execution, the data used for that instruction can

 

 

be changed.

(4)Destination (D)

The destination stores the data resulting from operation. Note that if the format

consists of

,

the data to be used for operation must have been stored into the destination before operation.

At the destination, always specify the device for storing data.
