Description This document outlines issues that are present in native APPID application. These issues are carried over to OPPID during the conversion. OPPID tries to handle these issues in a manner which will not disrupt appearance and content. This being said some of these issues will persist. Tie Ins Equipment Trim Valves Control Valves Pressure Safety Valves Function Indicators Reducers Spec Breaks Nozzles on Vessel Heads Linked Page Connectors Instrument Loop Tie Ins APPID Ties-Ins were structured after Instrument bubbles, but the APPID native xdata stored in a Tie-In is incomplete. The leader line xdata is not present and the OPPID conversion compensates for this. When placing a Tie-In in APPID, the first point should be on a pipe run. After placing a Tie-In in APPID, the drag bubble does not work. If a drag bubble is performed, the old leader line is left in drawing and a new one is placed: potential issue with garbage data in APPID The Tie-In database information is not formatted and populated like other components. The Number and type are not populated (TIETYPE). There is no column for populating the Number value. For instance the INSTR table columns get populated with the tag parts (INUM,ITYP,INUM). The Tie-In only populates the Tag number. The conversion mapping explicitly does not map the Tag parts (number and type). Equipment Trim The conversion on APPID parametric equipment and trim conforms all the children into the main graphics. The Trim (insulation, Internals, packed, stacking…) do not have any intelligence, so that are grouped with the parametric equipment. When APPID equipment trim is added to parametric equipment, the xdata trim children are not added to the main xdata point. It is orphaned, that is, the xdata handle knows its parent, but the parent does not know about the child. This is why I do the scanning of drawing on conversion initialization. So this example shows the child handles that are on the main element. These do not contain all the elements that make up the parametric equipment and trim. As seen below, the orphaned child element is not part of the main parent collection of children. The Child element handles are the only elements that will be grouped with the conformed component. The fix gathers orphaned xdata which then can be applied to the conformed component. So in the list there will be a key with 792 and have a collection of handles, which will contain the element id 926. Orphaned Child element To determine a Equipment Parametric, the APPID type must be defined in EQUIPMENT_PARAMETRICS_LIST in AutoPLANT_PID_Conversion.01.07.ecschema.xml Schema list that indicates which Equipment keys are to be used as parametric containers. Key value is stored in EQUIP.EINT1 Valves In DIN mode, placing a float valve actually places a float control valve. Control Valves In APPID every possible valve body could become a CV. That is actually incorrect. The ones that shouldn’t be allowed to be CVs are the ones we convert to generic CV. Conversion will cloud these, see APPID Cloud Warning.docx Non-symmetric angle CVs do not have intelligence on them, indicating flow. Therefore they are converted with the APPID placement orientation. Pressure Safety Valves In APPID Pressure Safety Valves are treated like regular valves. They are in a single pipe run. In OPPID Pressure Safety Valves are treated like data change components. They split a pipe run into two pipe runs. Because of this inherent difference, they are converted to OPPID Control Valves, which go into a single pipe run and can have bubble style annotations Function Indicators These Function Indicators have unintelligent text and will only be conformed. So if an instrument bubble is moved these indicators will have to be moved manually. Boost S.P. Proportional Convert Derivative d/dt Inv Derivative I/D Reducers Reducers in multiline pipelines do not convert correctly. Spec Breaks Spec Breaks placed with leader line doesn’t convert Nozzles on Vessel Heads When a nozzle is placed on equipment in APPID and AutoNozzle is on, two blocks are inserted: the Nozzle symbol and a Run Terminator symbol. The Nozzle symbol only has a grouping link to the equipment. The Run Terminator symbol has the intelligent link to the database and is considered a Nozzle. If the nozzle is placed on a vessel head, the Pipe Run line and the Run Terminator symbol do not intersect. This causes issues in the conversion due to the fact that the conversion uses intersection scanning to determine relationships and connections. OPPID requires this. Incorrect nozzle connection Correct nozzle connection To correct this in OPPID the Pipe run must be dragged off the nozzle and then back on to the nozzle. Linked Page Connectors The first of 2 linked dwgs to be converted would display an error, since the other drawing has yet to be converted. Once both drawings are converted, the problem goes away automatically; the page connectors are linked Instrument Loops If an instrument is associated with a loop, there is the possibility that key associated fields might not match. This could happen for the (I)AREA and SERVICE columns in the INSTR and LOOP tables. Below is a case of the SERVICE values not matching. When the conversion is run all the instruments are converted and the SERVICE associated item is related to the instruments. In this view you can see the instruments have a SERVICE of WC INSTR KEYTAG TAG_TYPE TAG_NO SERVICE 0000000367 AT_INST_ 50-FT-021 WC 0000000370 AT_INST_ 50-FC-021 WC 0000000371 AT_INST_ 50-FY-021 WC The loop relationship is added to individual instruments. The loop now dictates the SERVICE relationship, since the loop is now the parent. In this view the SERVICE is empty, so now there is a conflict. The instrument has a relationship to a known SERVICE, but the parent loop overriding that relationship with an empty SERVICE LOOP KEYTAG TAG_TYPE TAG_NO SERVICE 0000000533 AT_LOOP 50-F-020 0000000534 AT_LOOP 50-F-032 0000000535 AT_LOOP 50-F-010 There are several ways to correct this. Update the LOOP.SERVICE to match INSTR.SERVICE (or vis versa) Once the Conversion is complete select LOOP or Instruments and update Associated items
