Reading Tags

Realtime (Live) Values

Realtime (live) tag data functionality is supported by the connector, allowing for the reading of tag values in realtime. This functionality may be enabled connector-wide, per Ewon Flexy, or per tag.

Connector-Wide

To enable realtime (live) tag data functionality connector-wide, set the Read all values in realtime field to true in the connector configuration.

1. From the Ignition Gateway webpage, navigate to the Config section.
2. Select the Ewon Connector option from the left-hand menu.
3. Enable the Read all values in realtime option.
4. Click the Save Changes button, then restart Ignition.

Per Ewon Flexy

To enable realtime (live) tag data functionality per Ewon Flexy, set the _STATUS/ForceRealtimeData tag to true in each Ewon Flexy's tag folder.

1. From the Ignition Designer, navigate to the Tag Browser tool.
2. Expand the All Providers directory.
3. Expand the Ewon directory (associated with the Ewon Connector).
4. Expand the Ewon Flexy's directory.
5. Expand the _STATUS tag folder.
6. Set the _STATUS/ForceRealtimeData tag to true.

note

If you are not in read/write mode, you will need to switch to read/write mode to set the tag value.

Per Tag

To enable realtime (live) tag data functionality per tag, set the ForceRealtimeData property to true in the tag's properties.

1. From the Ignition Designer, navigate to the Tag Browser tool.
2. Expand the All Providers directory.
3. Expand the Ewon directory (associated with the Ewon Connector).
4. Expand the Ewon Flexy's directory.
5. Select the tag and expand it to view its properties.
6. Set the ForceRealtimeData property to true.

note

If you are not in read/write mode, you will need to switch to read/write mode to set the tag value.

Where to Access Tags

The tags created by the connector are native Ignition tags and are updated cyclically by the connector based on the polling rates set during configuration of the module.

The Tag Browser tool in Ignition Designer can be used to read and write tag values.
