Is there any specification stating that signals indicating the status of electric pumps that are not involved in cascade control cannot use 485 communication?

Are there any specifications stating that status signals for electrical pumps that are not involved in cascade control cannot use 485 communication, or are there such qualitative descriptions indicating that they can use 485 communication?
Currently, there are no regulations specifying that status signals from electrical pumps that are not part of a chain control system cannot use 485 communication, or that they can use it. However, in practical applications, it is necessary to determine whether 485 communication can be used based on specific circumstances. If the use of 485 communication affects the safety and reliability of the system, then its use should be prohibited ； If using 485 communication does not affect the safety and reliability of the system, then it can be considered for use. It is best to conduct evaluations and make decisions during the design phase by taking into account actual application scenarios. -
Relatively speaking, the reliability of 485 communication is slightly lower compared to direct connection using IO signals; chain signals are generally not transmitted via 485 communication.
