Time and Date Operations:

• Time of Day in Advanced Ladder

• Days of Week in Advanced Ladder

• Days of Month in Advanced Ladder

• Months of Year in Advanced Ladder

• Start and End Year in Advanced Ladder

• Set OCS Time/Date in Advanced Ladder

 

Time and Date Operations take either fixed or Register Type and Offset (address) as input. The fixed or register values are compared with the current RTC time in the OCS. When the current RTC time/day/date/month/year of OCS is between the input given, power is passed through the element to its output, which can be used to set or clear an indicator coil.

 

For example:

Element	Inputs Given	Power Flow
Time of Day	Start time: 11:45 End time: 16:45	The power will be passed when the RTC time in the OCS is between 11:45 and 16:45 every day.
Days of Week	Monday, Wednesday, and Friday	The power will be passed on Mondays, Wednesdays and Fridays of every week.
Days of Month	5, 15 and 25	The power will be passed on 5th, 15th and 25th of every month.
Months of Year	January, July	The power will be passed from 1st to 31st January and 1st to 31st July of every year.
Start and End Year	Start Year: 2017 End Year: 2019	The power will be passed from year 2017 to 2019.
