Practical projects often combine axes: a control engineer may view the plant by functional axis (control loops), maintenance by product axis (equipment), and operations by location axis (areas/units).
Engineering students often have free database access via IEEE Xplore or similar academic networks. iec 61346-1 pdf
The principles from IEC 61346 and, more importantly, its successor IEC 81346 are not just theoretical. They are the backbone of effective technical documentation across numerous industries. Practical projects often combine axes: a control engineer
