SR
When the PLC runs, the value in SR408
increases by one every scan cycle. SR408
SR408
counts from 0 to 32767, and then from
-32768 to 0.
The pulse is ON for n seconds and is OFF
for n seconds during the 2n second clock
*SR409
pulse. The interval n is stored in SR409,
and the setting range is 1~32767.
The pulse is ON for n milliseconds and is
OFF for n milliseconds during the 2n
*SR410
millisecond clock pulse. The interval n is
stored in SR410.
The current scan time is stored in SR411
and SR412, and the unit of measurement is
SR411
100 microseconds. The value of the
millisecond is stored in SR411. (The range
is 0~65535.) The value of the microsecond
is stored in SR421. (The range is 0~900.).
For example, 12 is stored in SR411 and
SR412
300 is stored in SR412 when the current
scan time is 12.3 milliseconds.
The maximum scan time is stored in SR413
SR413
and SR414, and the unit of measurement is
100 microseconds. The value of the
SR414
millisecond is stored in SR413.
The maximum scan time is stored in SR415
SR415
and SR416, and the unit of measurement is
100 microseconds. The value of the
SR416
millisecond is stored in SR415.
