I am currently working with a Weintek FXHD-820 HMI, and I need assistance in setting up daily and monthly data logging. I am reading data from a Modbus float register, and I would like the HMI to store and display this data in historical form (daily and monthly records) using EasyBuilder Pro.
Could you please share step-by-step instructions or documentation on the following:
How to configure data sampling to store values daily and monthly.
How to save Modbus float values into history logs.
How to display the historical records on the HMI (daily / monthly trend or table).
Within our data sampling object we can set it up to have a time based trigger, or trigger by a bit. Did you want to collect data once a day/month, or different times throughout the day?
Furthermore, what device are you using to connect to the Weintek HMI?
Lastly, below is a video that should help you get started as it goes through our Data Sampling object and Trend Display. Data Sampling and Trend Display Video.
I have use air flow meter via RS-485 communication and I am now using Modbus register 4x1268 to calculate the daily flow. The system is also accumulating this reading to determine how much air is consumed on a daily and monthly basis.
Now, I need your support on how to properly set and store the daily and monthly data in the HMI so that the reports can be viewed accurately.
Your continued assistance and technical support will be highly appreciated.
Our recommendation is to record data in the Data Sampling object at intervals of 1 second or longer to generate daily reports, and then use a Trend Display to show these values.
For monthly reports, please use a longer sampling interval, such as 10 minutes or 1 hour. To reliably review the data, back up the samples as a CSV file using the Backup object, then use a third party application like Excel to generate graphs.
You can also try setting the Trend Display’s distance between data samples to 1 pixel and see if the display accurately captures the sampled data, but the Excel graph will likely be more precise.
For a table-style display of the data sampling object, we recommend using the History Data Display and configuring the daily and monthly channels with the sampling intervals discussed in our previous response.
Please let us know if you have any other questions.
