Is it necessary to consult the design institute for any changes to the interlocks in a DCS system?

Could risk discussions be held within the company to identify the risks associated with changes, and then decide on whether a change is necessary or not?
Sure, as long as you can take on the responsibility. In fact, the workshop often makes adjustments to certain interlocks that interfere with operation.
The DCS interlock can be changed whenever you want: lol

Sure. It is also possible to entrust a design institute to participate as well
No matter how reasonable the interlock changes may be, the design institute generally will not approve your modifications. There is no benefit to him at all; instead, he faces the risk of having to take responsibility. So, generally it’s discussed within the company, and then **the junior manager signs off before proceeding with it.
Interlock changes are mainly due to process-related reasons. After the facility is built and put into operation, such changes are decided through discussions among the company’s internal production operations, process, and instrumentation teams; they have little to do with the design institute
Unless the process package is a process designed that way
Not necessarily, but the reasons for the change must have thorough analysis and supporting evidence
Internal discussions lead to the creation of an interlock change order, which is then forwarded for archiving
It’s sufficient to keep proper change records and conduct analyses within one’s own company; there is no need to consult a design institute.
