Overview:
After defining how the data is sampled, by sampling time, address, or data length, the sampled data can be saved to the designated location, such as HMI memory, SD card, or USB disk. Trend Display and History Data Display objects can be used to display sampling records.

Data Sampling Management
Create a new Data Sampling object first by the following steps: 1. From the menu select [Objects] and click (Data Sampling). 2. Click [New] to finish relevant settings.

Creating a New Data Sampling
The following introduces how to set a new Data Sampling. eMT, iE, XE, mTV Series
Sampling mode High priority Data sampling processes with this feature enabled will be prioritized. Please note that too many priorities can slow down update rate of other objects. Time-based Samples data in a fixed frequency. The (Sampling time interval) can be set from “0.1 second(s) to 120 mins”. Trigger-based Triggers data sampling by the status of a designated bit address. Mode Conditions to trigger Data Sampling: (OFF - ON) Triggers sampling when the status of the address changes from OFF to ON. (ON - OFF) Triggers sampling when the status of the address changes from ON to OFF. (OFF - ON) Triggers sampling when the status of the address changes. Set ON/OFF after triggered If selected, after triggering Data Sampling, the system will set the designated bit address back to ON/OFF state.
Data Record (Real-time)
In Real-time Mode, when [Auto. stop] is not selected, the max. number of data records can be saved on HMI is 86400. When the number of records exceeds 86400, the earliest data will be deleted. Data Format Data of different formats in consecutive registers can be sampled. For example, setting: LW-0 (16-bit Unsigned), LW-1 (32-bit Float), and LW-3 (16-bit Unsigned).
