4. Program description

 After the Right Rotation button is pressed, X0 will be turned ON, and the instruction ZRST

will be executed. When ZRST is executed, Y0~Y17 and M10~M11 are reset to OFF. When

the instruction SET is executed, Y0 and M10 are set to ON. When M10 is ON, the

instruction TMR is executed. After 200 milliseconds, T0 will be turned ON, and the

instruction ROL will be executed. When ROL is excuted, Y1 is ON. After ROL is executed,

the instruction RST will be executed. When RST is executed, T0 is reset.

 In the next scan cycle, T0 starts counting again. After 200 milliseconds, ROL will be

executed again, and Y2 will be ON. Y0~Y17 are turned ON for 200 milliseconds in order.

 The use of the Left Rotation button is similar to the use of the Right Rotation button.

However, the Left Rotation button uses the instruction ROR to turn ON the neon lamps in

the order Y17~Y10 and Y7~Y0.

 After the Reset button is pressed, X2 will be turned ON, Y0~Y17 and M10~M11 will be reset,

and all the neons will be turned OFF. ZRST put after the rising edge-triggered contact

ensures that the neon lamps are turned ON from Y0 or Y17.
