Get From Device

Select the device/PLC used for clock information.

Update Trigger

Select the timing for updating the clock from [Frequency], [Bit ON], or [Bit OFF].

Specifies the frequency from 1 to 1440 minutes. Updates the clock at the specified frequency.

Updates the clock when the bit address turns ON or OFF.

  • When using [Frequency], there is a maximum error of 1 second when updating the clock from the LS area.

  • When using [Frequency], the clock is updated on the following conditions, in addition to the defined frequency.
    Until the clock update is complete, parts on the display unit will not operate.

Customize

You can use this setting to get clock data stored in the specified address and data format.

Time Area Start Address

Specify the start address where clock data will be stored.

Read Area Size

Specify the number of words for storing clock data from 1 to 6.

Format

Define whether clock data is stored in single word units, or words are separated into High/Low units.

In single word units, stores the year, month, day, hours, minutes, and seconds.

In words divided into High/Low units, stores the year, month, day, hours, minutes, and seconds.

Data Type

Choose the data format of the stored clock data from [16 bit Dec], [16 Bit BCD], [32 bit Dec] or [32 Bit BCD].

  • When using [16 bit Dec] or [16 bit BCD] and the address specified in the [Time Area Start Address] field is 32 bits, no data is stored in the top 16 bits.

  • When using [32 bit Dec] or [16 bit BCD] and the address specified in the [Time Area Start Address] field is 16 bits, 2 words are used for each clock data.

Number of Words to Use

Displays the number of words used for clock updates, as defined in the [Read Area Size].

Word

Displays the addresses as defined in the [Time Area Start Address] and [Read Area Size] fields.

For each address, specify what is stored in the word, [Year], [Month], [Day], [Hours], [Minutes], or [Seconds]. Select [None] to store no data in the address.

  • When there is an error in getting data for the seconds, and data for the year, month, day, hours, and minutes is okay, the seconds is reset to zero. An error message displays if there is an error in getting the year, month, day, hours, or minutes.

  • When there is an invalid value for the year, month, day, hours, or minutes, the value is not stored and an error message dislays. After the error message displays, if the next clock update produces a valid value the error message will clear.
    Valid values are as follows.
    Year: 0 to 99
    Month: 1 to 12
    Day: 1 to 31 (Top limit depends on the number of days in the month)
    Hours: 0 to 23
    Minutes: 0 to 59
    Seconds: 0 to 59

  • Although the day of the week (stored in LS2054) is not updated using this feature, the value in the day of the week storage area (LS9310) is calculated when the date is updated.
