10. The initial clock pulse

 SM404~SM410, and SR409~SR410

The PLC provides seven types of clock pulses. When the PLC is supplied with power, the

seven types of clock pulses act automatically. Users can set the interval of the clock pulse in

SM409 and SM410.

10 millisecond clock pulse during which the pulse is ON for 5 milliseconds and is

OFF for 5 milliseconds

100 millisecond clock pulse during which the pulse is ON for 50 milliseconds

and is OFF for 50 milliseconds

200 millisecond clock pulse during which the pulse is ON for 100 milliseconds

and is OFF for 100 milliseconds

One second clock pulse during which the pulse is ON for 500 milliseconds and

is OFF for 500 milliseconds

Two second clock pulse during which the pulse is ON for one second and is

OFF for one second

2n second clock pulse during which the pulse is ON for n seconds and is OFF

for n seconds

The interval n is specified by SR409.

2n millisecond clock pulse during which the pulse is ON for n milliseconds and is

OFF for n milliseconds

The interval n is specified by SR410.

The clock pulses are illustrated as follows.

SM404 (10 ms)

SM405 (100 ms)

SM406 (200 ms)

SM407 (1 sec)
