Ewon Technical Forum

Hi,
    I have some querry about Ewon flexy as below,

1.Flexy is logging data in the internal memory (1,000,000 timestamp points) and we can download using EBD. If i connect Ewon with esync database server, Is it possible to view more than [font=Calibri Regular]1,000,000 timestamp pointts  datalog  by picking the date and time in the ewon table or is it possible to download esync datebase in the CSV Format[/font] using EWON EBD ?

2.We have 2 Profibus DP Slave equipment (Not PLC) AND 5 Modbus RTU Slave equipment in the same location. Which flexy model is suitable  aquire data from these equipments ?

3.we have 3 Flexy units in the three differant buildings connected to LAN and these 3 flexy loaded with indivisual viewon pages (monitor and control ).Flexy 1 have main viewon page we should enter log in credentials to enter the 1st viewon page then to go the remaining (2,3) flexy viewon pages i have set a button with URL in the  flexy 1 Main viewon page. But again we have to log in flexy 2,3 to view the viewon pages. Flexy 1 viewon login is ok and remaining 2,3 flexy should not ask login.Flexy 1,2,3 all have read write tags.how to resolve this ?

Hi

Please find below replies as per our understanding.

1) Esync is basically based on MySql Platform. Ewon Can push the data to Esync Server PC with time synchronization. As Esync is based on MySql database it can save morethan 1,000,000 timestamp points. To query the data from Esync Database, you can use applications like Workbench which can download your conditional query data.

2) Profibus DP of Siemens PLC can be directly connected to Ewon. if the device is not Siemens PLC, then the recommendation would to be to use a converter in between to convert Profibus DP to Modbus TCP / OPC (Anybus AB7634 / AB7558) which can be connected to Ewon to read data. 5 Modbus RTU (RS485) Can be multi-dropped (Daisy Chain Topology) and connected to Single Ewon.

3) For reading Flexy 2 & 3 using Flexy 1, Anonymous option will be helpful. For writing authentication is required as per our understanding. Link
