Ewon Configuration

When setting up an Ewon, follow all standard Ewon Flexy documentation and installation guides. Documentation, installation guides, and more for the Ewon Flexy can be found at https://websupport.ewon.biz/support.

In addition to the standard Ewon Flexy documentation, follow these additional steps to prepare the Ewon for use with the Ignition Ewon® Connector.

I. Link Ewon to Talk2M

Step 1

Open the Ewon web page.

Step 2

Navigate to the VPN Wizard page by clicking Wizards at the top right of the page, and select VPN.

Step 3

Select the Configure Talk2M connectivity option.

Step 4

Follow the prompts to connect the Ewon to Talk2M.

Step 5

Once the VPN Wizard is complete, you may proceed to the next section.

II. Setup Historical Logging for Tags

Step 1

Open the Ewon web page.

Step 2

Navigate to the Values page (On the left-hand menu, click Tags > Values).

Step 3

Change the MODE to Setup.

Step 4

For each tag that requires logged data, double-click the tag to open the Tag configuration menu.

Step 4a

Scroll down to the Historical Logging section and check the Historical Logging Enabled checkbox.

Step 4b

In the same Historical Logging section, enable either deadband or interval logging.

Deadband Logging

The Logging Deadband field triggers logging when the tag's value changes by a particular amount. For example, a logging deadband of 2 means that a tag will be logged when the value changes by 2 or more. A negative value in the logging deadband field disables logging on value change.

Interval Logging

The Logging Interval field triggers time-based logging. For example, a logging interval of 60 means that the tag will be logged every 60 seconds. A logging interval of zero (0) disables time-based logging.

Step 4c

Once configured, click Update Tag on the bottom right of the page.

Step 5

Once all tags have been configured, you may proceed to the next section.

tip

You may change the MODE back to View to see the tag values once you are done configuring the tags.

III. Enable Historical Data In DataMailbox

Step 1

Open the Ewon web page.

Step 2

Navigate to the Data Management page (On the left-hand menu, click Setup > System > Main > Data Management).

Step 3

Check the Historical Data checkbox.

Step 4

Set the DataMailbox upload interval to a reasonable number for your application.

info

The DataMailbox upload interval sets how often the Flexy will send batches of historical data to DataMailbox and does not affect the frequency at which tag values are logged.

Step 5

Click Update at the bottom of the page to save the changes.

Step 6

Once the changes have been saved, you may proceed to the next section.

Connector Configuration

Step 1

Open the Ignition Gateway web page.

Step 2

Navigate to the Config page (On the left-hand menu, click Config).

Step 3

Under the Tags section, click Ewon Connector.

General
- Enabled - Option to enable or disable the module.
  info
  When this option is disabled, the module will not run, but can remain installed and configured.
  This option is useful for temporarily disabling the module without losing the configuration, or for maintenance purposes.
- Poll Rate in Minutes - Option to configure the poll rate for historical data via DataMailbox
  info
  This option allows for the configuration of how often the module polls for historical data via DataMailbox.
  The default value is 1 minute, but this can be increased (in minute intervals) to reduce DataMailbox usage.
- Realtime Poll Rate in Seconds - Option to configure the poll rate for realtime data via M2Web (where applicable)
  info
  This option allows for the configuration of how often the module polls for realtime data from an Ewon via M2Web.
  The default value is 10 seconds, but this can be increased or decreased (in second intervals) to reduce Ewon and M2Web usage.
- Metadata Update Rate in Minutes - Option to configure the poll rate for Ewon/tag metadata updates
  info
  This option allows for the configuration of how often the module polls for Ewon/tag metadata. This includes new Ewon devices, new tags, and updated tag metadata such as descriptions and data types.
  The default value is 30 minutes, but this can be increased or decreased (in minute intervals) to reduce Ewon and M2Web usage.
  Regardless of the value configured, the module will perform an initial metadata update upon startup. Until this initial metadata update is complete, the module will not poll for tag data.
Talk2M Account Information
- Account - Option to configure the Talk2M account to use for the module
  info
  This option allows for the configuration of the Talk2M account name which will be used for the module.
- Username - Option to configure the Talk2M username to use for the module
  info
  This option allows for the configuration of the Talk2M username which will be used for the module.
- Change Password? - Option to enable the password field for the Talk2M account
  info
  This option enables the password field for the Talk2M account. This field is disabled by default to prevent unexpected or accidental password changes.
- Password - Option to configure the Talk2M password to use for the module
  info
  This option allows for the configuration of the Talk2M password which will be used for the module. This field is disabled by default to prevent unexpected or accidental password changes, and must be enabled by selecting the Change Password? option above.
- Talk2M Token - Option to configure the Talk2M token to use for the module
  info
  This option allows for the configuration of the Talk2M token which will be used for the module.
  Talk2M tokens can be generated using eCatcher. To learn more about Talk2M tokens and how to generate them, please refer to Section 4.6 of the DMWeb API reference guide found at: DMWeb API Reference Guide
- Talk2M Developer ID - Option to configure the Talk2M developer ID to use for the module
  info
  This option allows for the configuration of the Talk2M developer ID which will be used for the module.
  Talk2M developer IDs must be requested from HMS. If you do not have a Talk2M Developer ID, you may request one here: https://developer.ewon.biz/registration.
Ewon Device Information
- Ewon Username - Option to configure the Ewon device username to use for the module
  info
  This option allows for the configuration of the Ewon device username which will be used for the module. This username must be identical for all linked Ewons.
  All linked Ewons must have at least one common user account to enable realtime and write functionality via M2Web. The username and password can be any valid combination, but must be consistent across all linked Ewons.
- Change Password? - Option to enable the password field for the Ewon device
  info
  This option enables the password field for the Ewon device. This field is disabled by default to prevent unexpected or accidental password changes.
- Ewon Password - Option to configure the Ewon device password to use for the module

This password must be identical for all linked Ewons.
  All linked Ewons must have at least one common user account to enable realtime and write functionality via M2Web. The username and password can be any valid combination, but must be consistent across all linked Ewons.

History
- History Enabled - Option to enable DataMailbox historical data logging to a history provider.
  info
  When this option is enabled, the connector will log historical data to the history provider specified in the Target History Provider field.
  When this option is disabled, the connector will only log historical data to the tag provider.
- Target History Provider - Option to select the history provider to log historical data to.
  info
  When the History Enabled option is enabled, the connector will log historical data to the history provider specified in this field.
Advanced
- Debug Enabled - Option to enable debug logging.
  info
  When this option is enabled, the connector will log additional information to the Ignition console. This option is useful for troubleshooting, and includes information such as:
  - HTTP request IDs and status updates (i.e., HTTP request started, HTTP request finished)
  - Consistent warning logs (i.e., offline Ewon warnings not suppressed after the first warning)
  - General connector state information (i.e., start and finish of polling cycles)
  Unless you are troubleshooting, it is recommended to leave this option disabled. Debug logging may impact performance.
- Combine Live Data: Option to combine live data with historical data.
  info
  When this option is enabled, tags that are read in realtime will be combined with historical data, if available. This option has no effect when the Read all values in realtime option is enabled.
  The connector will only combine historical data with realtime data if the historical data was already read from DataMailbox. For example, when some tags (not all) are configured to be read in realtime, a DataMailbox transaction will be performed to read the historical data for the tags that are not configured to be read in realtime. If historical data is also included for the tags that are read in realtime, the connector will combine that historical data with the realtime data (instead of omitting the historical data).
- Read all values in realtime - Option to always read all tag values in realtime.
  info
  When this option is enabled, all tags will be read in realtime.
  This option disables DataMailbox reads. Historical values logged on the Ewon will not be logged in Ignition.
- Tag Write Buffer Length (ms) - Option to configure tag write buffering (and the associated buffer length).
  info
  When this option is configured to -1 or any value below the minimum of 100, tag write buffering is not enabled, and tag writes are sent to the Ewon immediately. When this option is configured to a value above the minimum of 100, tag writes will be buffered for the specified length of time before sending them to the Ewon.
  Each time a tag is written, it is added to a buffer. If it is the first tag in the buffer, a timer is started. Otherwise, it is added to the existing buffer. When the buffer length timer has elapsed, all buffered tag writes are sent to each Ewon in a single request.
- Sort Tags by Group - Option to enable tag sorting by group.
  info
  When this option is enabled, tags are sorted into folders for each Ewon, based on their tag groups.
  For each Ewon, a folder is created for each tag group combination and tags are placed in their respective group folder. If a tag is not in a group, it is placed in the root Ewon tag folder. If a tag is in multiple groups, it is placed in the folder with a name that is the concatenation of all groups. For example, if a tag is in the groups A and C, it will be placed in the folder AC.
- Disable Tag Name Checking - Option to disable tag name checking.
  info
  When this option is enabled, tag names are not checked for invalid characters.
  By default, tag names are checked for invalid characters. If a tag name contains an invalid character, it is replaced with an underscore (_).
