What type of messages takes precedence over all others except for an E-Stop?

The type of messages that takes precedence over all others, except for an emergency stop (E-Stop), is related to the critical nature of operational safety and functionality within a system. Editing and operation messages are essential because they often pertain to the real-time management and control of machinery. These messages may include commands or alerts that directly influence the operational status of equipment and its interaction with safety protocols.

In an industrial context, editing and operation messages can dictate immediate actions required to maintain safety and efficiency within an engineering system. Since these messages can involve adjustments to operational parameters or responses to safety conditions, they must be prioritized to ensure the correct functioning of the equipment and prevent hazardous situations. This priority ensures that operators are immediately aware of any critical operation changes they need to make.

Other message types, while important, do not bear the same level of urgency in immediate operational contexts. For instance, user manual instructions, safety warnings, and diagnostic logs serve significant roles but typically do not require the immediate attention that editing and operation messages do. They can be referenced or acted upon as situations allow, rather than needing instant recognition like an operational command in progress.
