Operands:

S: Start device for key input (occupies 4 consecutive devices)

D1: Device storing the value to be

displayed in 7-segment display D2: Output device for 7-segment display

n: Configuration

setting of output signal (n = 0~3). Please refer to explanations of SEGL instruction for the n usage.

Explanations:

1.ARWS instruction displays the value set in device D1 on a set of 4-digit 7 segment display. PLC automatically converts the decimal value in D1 to BCD format for displaying on the 7 segment display. Each digit of the display can be modified by changing the value in D1 through the operation of the arrow switch.

2.Number of D2 only can be specified as a multiple of 10, e.g. Y0, Y10, Y20…etc.

3.Output points designated by this instruction should be transistor output.

4.When using this instruction, please fix the scan time, or place this instruction in the timer interruption subroutine (I610/I699, I710/I799).

5.There is no limitation on the times of using this instruction in the program, but only one instruction is allowed to be executed at a time.

Program Example:

1.When the instruction is executed, X20 is defined as the Minus key, X21 is defined as the Add key, X22 is defined as the Right key and X23 is defined as the Left key. The keys are used to modify the set values (range: 0 ~ 9,999) stored in D20..

2.When X0 = ON, digit 103 will be the valid digit for setup. When Left key is pressed, the valid digit will shift as the following sequence: 103→100→101→102→103→100.

3.When Right key is pressed, the valid digit will shift as the following sequence: 103→102→101 →100→103→102. Besides, the digit indicators (LED, Y24 to Y27) will be ON for indicating the

position of the valid digit during shift operation.

4. When Add key is pressed, the content in the valid digit will change as 0 → 1 → 2 … → 8 →

9→ 0 →1. When Minus key is pressed, the content in the valid digit will change as 0 → 9 → 8 … → 1 → 0 → 9. The changed value will also be displayed in the 7-segment display.
