What do GOA and GOS mean in the PID process flow diagram?

You can take a look at the code explanation before the PID diagram
Any PID diagram produced by a design firm should come with legends, and the firm’s own legends shall prevail.
The image was uploaded; it wasn’t possible to do so yesterday. Unfortunately, this image doesn’t have any legend explaining the Austrian equipment
That won’t happen. This situation might occur with first-class design institutes, but their diagrams can be found on Baidu; if they cannot be found, one can call the design institute for inquiries.
Generally speaking, GOS: GO refers to the position status of the valve – whether it is open or closed – as indicated in the control room. S refers to the fact that this valve is interlocked with others. The same goes for GOA; A stands for alarm, and in this case it’s on, but I’m not sure about the setting for turning the alarm off.
Could the original poster tell us what industry this belongs to? What device is connected to the PID? With a reference point, it’s possible to make some guesses. The speculation upstairs is fairly reasonable; it would be better if you could provide more information.
