Instrument mapping in SAP
Hi Experts, I want to know how instruments and control is mapped and testing is done in manufacturing and process plants. I usually represent field instruments, junction box, PLCs, MCCs and control panels as equipments. But I am facing problem for mapping loop because controllers in PLC and Junction boxes are common for multiple loops.
Controller I am mapping as sub-equipment under PLC . But loop number mapping in function location is becoming difficult. Kindly give best way you guys have mapped from experience point of view and domain point of view.
