Notification: Message Delivery Tab

On this tab, you specify how you want PCo to deliver notification messages.

On the Plant Connectivity Management Console screen, select a notification and click on the Message Delivery tab.

In the Reliability screen area, enter the required data for reliable message delivery using the following table:

Field	Description
Maximum Number of Retries	Maximum number of send attempts before message delivery is considered to have failed. The default value is `3`. Note If you specify the value `0`, there are no retries. End of the note.
Retry Interval (Seconds)	Number of seconds before the next attempt to send the message. The default value is `30 seconds`.

In the Failed Message Persistence screen area, specify how you want failed notification messages to be stored. The failed messages are displayed in the agent instance on the Message Failures tab. You can choose from the following options:
- KeepAll
  Saves all failed messages.
- KeepFirst
  Saves the first failed message and ignores subsequent messages.
- KeepLast
  Saves the most recent failed message and removes previous messages.
- KeepSpecified
  You use this setting to specify that all failed messages that are older than the time you entered in the Deletion of Failed Messages After ...min field are to be deleted. For example, if you entered 60 min and a new failed message comes along, all stored failed messages that are older than 60 minutes are deleted.
In the Lifetime screen area, specify how long you want messages to be kept in the queue.
If the notification message cannot be delivered after the specified duration has elapsed, this message is displayed in the agent instance on the Expired Messages tab.
In the Message Bundling screen area, you can activate the message bundling function by selecting at least one of the checkboxes:
- Fixed Number of Messages
- Maximum Accumulation Time
Message bundling is a procedure in which notification messages can no longer be sent individually; instead, they are bundled in one large notification message and sent together to the connected destination system.
