Add a new discrete tag - j5 - 30 - Help - Hexagon

To add a new discrete tag to the Tag Watch List:

1. Click Add . The Adding window opens.

   

2. Enter the tag's details (the fields with orange labels are required):

   • Tag - Enter a name for the tag. This name needs to be unique in the j5 Event Manager application. The name can remain unchanged even if the underlying data source or process tag name changes. We recommend that the tag name doesn't contain any spaces.

   • Variable Type - Select Discrete from the list.

   • Datasource - Select the tag's data source from the list.

   • Datasource Tag - Select the tag from the list.

   • Data Type - Select Integer or Text from the list.

   • UOM - Enter the appropriate unit of measurement for the tag’s data.

   • Description - Enter a description for the tag.

   • Site, Section, Area, Unit - Select the operational area information for where the tag is positioned.

   • Monitoring Strategy - Choose how the data is retrieved.

     • Poll: This option retrieves a single value at each polling interval.

     • Query for Updates: This option retrieves all of the values since the last retrieval occurred.

     • Subscribe for Updated: This option receives values pushed to it by the data source and does not poll. This option may result in a high network usage, as the number of push events is determined by the data source. The number of entries with this option should be carefully considered and tested.

   • Target Polling Frequency - If you select Poll or Query for Updates, choose how frequently the data is retrieved.

   • Tag Excursion Delay - An event is only triggered when the tag's trigger state exceeds this time period. Refer to Tag excursion delay for more information.

   • Disable Events? - Choose when you want the events from this tag to be disabled.

     • Never - This is default selection. The events from this tag aren't disabled.

     • Always - All of the events from this tag are disabled.

     • Tag - The events from this tag are disabled when the Controlling Tag value is in the configured state.

   • Controlling Tag - This field appears when the Tag option from the Disable Events? list is selected. Enter the name of the controlling tag (the tag name in its Tag box) and the state that should disable the events for this tag separated by a period (for example, VacuumPump.OFF).

     

     • The controlling tag must be a discrete tag.

     • The controlling tag must be actively monitored.

   • General Distribution List(s) For Raised Events - An email is sent to the distribution list/s members when an event is triggered. Refer to Create a new j5 Distribution list for information on how to configure distribution lists.

     

     • When no Target Form is selected, an email is sent to the selected distribution lists for every state.

     • When a Target Form is selected, only one email is sent per state (for example, if the tag values go from Hot to Boiling, and then back to Hot, an email is sent for the first Hot and Boiling, but not when it goes back to Hot).

3. If aggregate event information is required in another application, select the relevant application from the Target Form list.

4. If a Target Form is selected, enter the Aggregate Period (minutes). This determines how long the events will be grouped together (one entry) in the target form. If there is another event after the aggregate period has expired, a new entry is created in the target form and the aggregate period is started again.

5. Click Save

When you have configured and saved a discrete tag, a Discrete States tab appears. This tab is used to define the discrete states for the tag.

To add a discrete state:

1. Select the Discrete States tab.

2. Click Add . Enter a label for the state in the State Label box. This is displayed in the j5 Event Manager for that state.

3. Enter a tag value in the Value box. This value must match the tag value options.

4. Give the operator instructions in the Description and Correct Actions boxes for when an alarm is raised.

5. In the Record State Change? column, select Yes if you would like events recorded when the tag is in this state.

6. In the Is Alarm State? column, select Yes to flag this state as an alarm condition.

7. Click Save

Continue until all of the possible states for the tag are defined on the Detail tab.

When you have configured a discrete tag and its states, monitoring should be enabled. To enable monitoring:

1. Select the Detail tab.

2. Click Edit

3. In the Monitoring Enabled? list, select Enabled.

4. Click Save
