Chapter 2 Devices 2-67 CPU5×0-RS2 CPU5×0-EN CPU5×1-RS2 CPU5×1-EN Attribute Default OFF STOP RUN SR Function ON RUN STOP clock (RTC): 01~12 SR393 Value of the day in the real-time clock (RTC): 1~31 ○ ○ ○ ○ – – – R 1 SR394 Value of the hour in the real-time clock (RTC): 00~23 ○ ○ ○ ○ – – – R 0 SR395 Value of the minute in the real-time clock (RTC): 00~59 ○ ○ ○ ○ – – – R 0 SR396 Value of the second in the real-time clock (RTC): 00~59 ○ ○ ○ ○ – – – R 0 SR397 Value of the week in the real-time clock (RTC): 1~7 ○ ○ ○ ○ – – – R 1 SR407 When the PLC runs, the value in SR407 increases by one every second. SR407 counts from 0 to 32767, and then from -32768 to 0.
○ ○ ○ ○ 0 0 – R/W 0 SR408 When the PLC runs, the value in SR408 increases by one every scan cycle. SR408 counts from 0 to 32767, and then from -32768 to 0. ○ ○ ○ ○ 0 0 – R/W 0 *SR409 The pulse is ON for n seconds and is OFF for n seconds during the 2n second clock pulse. The interval n is stored in SR409, and the setting range is 1~32767. ○ ○ ○ ○ – – – R/W 30 *SR410 The pulse is ON for n milliseconds and is OFF for n milliseconds during the 2n millisecond clock pulse. The interval n is stored in SR410. ○ ○ ○ ○ – – – R/W 30 SR411 The current scan time is stored in SR411 and SR412, and the unit of measurement is 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 300 is stored in SR412 when the current scan time is 12.3 milliseconds. ○ ○ ○ ○ 0 – – R 0 SR412 ○ ○ ○ ○ 0 – – R 0 SR413 The maximum scan time is stored in SR413 and SR414, and the unit of measurement is 100 microseconds. The value of the millisecond is stored in SR413. ○ ○ ○ ○ 0 – – R 0 SR414 ○ ○ ○ ○ 0 – – R 0 SR415 The maximum scan time is stored in SR415 and SR416, and the unit of measurement is 100 microseconds. The value of the millisecond is stored ○ ○ ○ ○ 0 – – R 0
