3. Instructions

• When CPS(114)/CPSL(115) is executed, the result is reflected in the Arithmetic Flags. Control the

desired output or right-hand instruction with a branch from the same input condition that controls

CPS(114)/CPSL(115), as shown in the following diagram.

• Do not program another instruction between CPS(114)/CPSL(115) and the instruction controlled by

the Arithmetic Flag because the other instruction might change the status of the Arithmetic Flag.

• The immediate-refreshing variation (!CPS(114)/!CPSL(115)) can be used with words allocated to

external inputs specified in S

will be performed for the external input word specified in S

compared. (Immediate refreshing cannot be performed on inputs allocated to Group-2 High-density

I/O Units or Units mounted to Slave Racks.)

Example Programming

When CIO 0.00 is ON in the following example, the eight-digit signed binary data in D2 and D1 is

compared to the eight-digit signed binary data in D6 and D5 and the result is output to the Arithmetic

• If the content of D2 and D1 is greater than that of D6 and D5, the Greater Than Flag will be turned

ON, causing CIO 20.00 to be turned ON.

• If the content of D2 and D1 is equal to that of D6 and D5, the Equals Flag will be turned ON, causing

CIO 20.01 to be turned ON.

• If the content of D2 and D1 is less than that of D6 and D5, the Less Than Flag will be turned ON,

causing CIO 20.02 to be turned ON.

Arithmetic Flag

(Example: Equal Flag)

In this case, the Equals Flag and output A will be turned

Arithmetic Flag

(Example: Equal Flag)

In this case, the results of instruction B might

change the results of CPS(114)/CPSL(115).
