Hi Anthony,

I wasn’t able to see a difference on my side, did having it start as a historical graph make any difference with your configuration?

Hi Tim,

Hi Tim,

The trend has already been updated, now it is shown in historical history, the same thing continues to happen, I am informed that we are in the same time zone, will something happen with the configuration of my Flexy?

If it is necessary to establish a connection by Teamviewer confirm me, I will still be available.

Did you start logging historical data before you set the timezone of the device? I’ve seen an issue like this in the past when somebody had done this

Hi Tim,

Thank you for your support, we have already managed to solve the problem we had with the historical trend in viewON.

Together with my project team, we have a query, how you could read real-type floating point data (32 bits) in the ewon flexy, correctly, because to monitor current and flow variables, we need to be given decimal data .

We tried configuring the data, but it shows us a number that is not correct, or maybe the problem is the lader program of the plc.

We will be attentive to your response.


Hi Tim

Please I need to solve the problem of the trend history that viewON shows me, it is 5 hours ahead, as it takes the London time zone (GMT),
Please, is urgent.

I look forward to your support.

Hi Anthony

Reading floats with Modbus on the Flexy can be done this way. When creating the tag you will need to add a modifier after the register number to specify the data type. This will tell the Flexy to read two addresses and combine them as specified.

Hi Tim,

Along with greeting you, I tell you that I am using the tia portal v14 software to configure the variables in a s7 300 plc and there are Dword and real variables, as I could read from the ewon, when I try to get erroneous data.

In the same way I take the opportunity to ask you if you could support me to carry out a program in the ewon to store the data in a MYSQL database automatically.

We are already days of presenting the project, we are grateful for its technical support and in the same way I would like to be clear that Ewon Flexy recommends me, 201 or 202 or 205, I would like to know its differences, and what happens with my internal storage in the ewon flexy 201 when I add a 1 GB memory, how many date and jora record points would it increase.

Ewon is very promising.

I will be attentive to your answer.

Hi Anthony,

What kind of errors are you getting when you try and read the Dwords and real variables from the S7-300 plc?

We also have this page that has PDFs that talk about how our M2Web API and Talk2M SDK could work for setting up MYSQL

Hi Tim,

Together with greeting you, I inform you that so far the tests are going well, we have already been able to read data in floating plots of our plc, we are close to presenting the project, before that we wanted to clarify some doubts.

Is it possible to send the ewon Flexy data to a platform not associated with you like the Amazon cloud and how would this be possible?

How can I export the ewon data to a computer automatically every 1 hour, to a database in MySQL or SQL.

The ewon Flexy team can work in places where there are teams that work with high frequencies, what alterations would it have with respect to the data?

How could I send sms messages as alerts?

If I buy an external 1G memory to expand the storage of the ewon Flexy, how many timestamp points would I expand?

I hope to clarify these doubts, I will be attentive to your response.


Hi Atte,

We do have examples on sending data to servers such as Microsoft Azure

To get data off of the eWon you have a few options. The API eSync , and the datamailbox .

This page should give you a good idea on how to calculate how much info you’d be able to store on a 1G expansion card
