Summary

eWON communication driver implements communication with eWON’s historical data cloud. It synchronizes the configured tags to the matching address in the cloud. Besides keeping the last value up-to-date, it also downloads all historical data for that tag if any is available in the DataMailbox.

Settings

In order to the tag be able to download the historical data from eWON’s DataMailbox, the tag setup in the points must have historian enabled on it. Otherwise, the driver will not try to download the historical data.

NOTE

To avoid conflicts when saving historical values, it is recommended to disable the "save on change" and "save trigger" in the historical table configuration. Otherwise, it will store the values downloaded from the driver and the values generated by the value change and trigger.



Nodes Configuration

Station Configuration

No IP (station) setting is necessary because it always communicates with the cloud service that has a static address.

  • Account: The name of the account registered at eWON’s DataMailbox.
  • Username: The name of the user associated with the account.
  • Password: User’s password to access the data.
  • DeveloperId: UID code for registered developers on eWON’s site.
  • eWON_Name: In eWON’s DataMailbox, tags are grouped in eWON’s and for each “device node”, there must be an associated eWON.


Point Configuration

The syntax for the eWON communication points is: <Tagname>

Where:

  • <Tagname>: is the name of the tag setup in the DataMailbox for the node’s eWON.
