25.14.3.2 Data Storage Methods

Sampled data is stored in sampling group units in the display unit.

Data sampled from the designated Cycles is stored with one of the following two methods.

  1. Overwrite old data and store the latest data.

  2. Do not overwrite data and store as a separate block.

The above storage methods are set by the [Overwrite old data after finishing the specified cycles] check box in the [Mode] tab's Extended area.

When the execution condition is [Constant Cycle], [Constant Cycle when Bit is ON], or [Bit Change], only method 1. is possible.

When the execution condition is [Set Time] or [Bit ON], you can select method 1. or 2.

When [Overwrite old data after finishing the specified cycles] is selected

Even after data has been sampled the designated Cycles, because old data stored in the display unit is overwritten with new data, sampling automatically continues.

When [Overwrite old data after finishing the specified cycles] is selected

After data has been sampled the designated Cycles, the next data is stored as a separate block. (A block is the sampling data collected from the designated Cycles.) Data from the designated Cycles x Blocks is stored. After that, data is not sampled.

When you store data into multiple, separate blocks, you can display and print each block. For example, if you want to sample data 10 times per day from Monday to Friday, store Monday's data in "block 0", Tuesday's data in "block 1", and so on. You can now print data for each day's information.
