# Convert PanelBuilder32 alarms

When a PanelBuilder32 application is converted to a Machine Edition application:

- The tag assigned to the PanelBuilder Message to Remote Device Data Tag connection is assigned to the ME Message connection.
- The tag assigned to the PanelBuilder Message to Remote Device Notification Tag connection is assigned to the ME Message Notification connection.
- The tag assigned to the PanelBuilder Message to Remote Device Handshake Tag connection is assigned to the ME Message Handshake connection.

## Differences between PanelBuilder32 alarm message functionality and Machine Edition alarm message functionality

Both Machine Edition and the PanelView terminal, follow this procedure:

1. Send the alarm message to the Data Tag connection.
2. Set the Notification Tag connection to 1.
3. Reset the Notification Tag connection to 0 when the Handshake tag changes to a new non-zero value.

The PanelView terminal performs the following additional steps that Machine Edition does not require:

1. Send Null (00) to Data Tag connection, overwriting the alarm message.
2. Set the Notification Tag connection to 1.
3. Reset the Notification Tag connection to 0 when the Handshake tag changes to a new non-zero value.

The Data Tag is now ready to accept a new alarm message.

Tip: | The maximum string length supported by FactoryTalk Machine Edition at runtime is 82 characters. Because some PanelBuilder32 protocols permit longer strings, some PanelBuilder32 alarm messages may be truncated after conversion.
