The machine timeline displays all messages that relate to the machine or its elements (parts, specifications, documents, sensors, KPIs). The messages are shown in chronological order.
Note: This means that messages that belong to same conversation can be shown separate from messages belonging to other conversations. If you want to see all messages grouped by conversation you need to go to the relevant subject and open the message list from there.
Events on the timeline can be color-coded to indicate their severity (normal, cautionary, or emergency).
