Schneider Electric Processor Adapter manual Time bits. The CPU must be running

Configuring an M1 CPU with Concept

Setting the Time

Overview	Once you have reserved a block of registers for the time-of-day clock, you have to
	set the correct time. With Concept, you must go online and set the register bits
	individually, using the following guidelines for setting the status bits and setting the
	time bits. The CPU must be running.
	Note: The time-of-day clock complies with guidelines for the year 2000.
Setting the
	The control register (4x) uses its four most significant bits to report status:
Status Bits
	Control Register
	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16
				1 = error
			1 = All clock values have been set
		1 = Clock values are being read
	1 = Clock values are being set

Note: The time-of-day clock sets itself to zero when it resets while it is running.

Setting the Time	The following table shows how the registers handle time-of-day clock data, where
Bits	register 4x is the first register in the block reserved for the clock:
	Register	Data Content
	4x	The control register
	4x + 1	Day of the week (Sunday = 1, Monday = 2, etc.)
	4x + 2	Month of the year (Jan = 1, Feb = 2, etc.)
	4x + 3	Day of the month (1...31)
	4x + 4	Year (00...99)
	4x + 5	Hour in military time (0...23)
	4x + 6	Minute (0...59)
	4x + 7	Second (0...59)
