Description
21901
With RTC_SET, a new time, date and day of the week of the real-time clock (RTC) can be set.
The function block creates a matrix from the input parameters consisting of the following data:
calendar day, month, year, hour, minute and day of the week
The controller sends this matrix along with the identifier (0x300 + Node-ID) to the real-time clock.
The real-time clock responds to this with the identifier (0x280 + node ID).
At the same time, the real-time clock sets the seconds counter internally to zero.
The output parameter RESULT informs about the current operating status of the POU.
