How to create an instrument loop through OPPID
From the TASKS menu, use the Instrument Loop button, in the Instruments section
You should then see the Instrument loop Creation dialog,
Go to the Loops tab and create a loop tag. Remember that actual loops are not shown on a P&ID.
Instruments belonging to a loop are shown on a P&ID.
Then, select the Instruments tab and all you should have to populate is the device type code. This will build the first instrument in the loop.
After the first instrument is built, use the ADD button on the lower left corner to add any other instruments you may require.
You will see a component Type Selection dialog. From there you can select your instrument component type. I selected Instrument Discrete. Then select OK
Once you are back in the Instrument Loop Creation dialog, please make sure you are back on the instruments tab. From there you can pick a new device type code, just as you did above
Then, you can use the ADD button again to repeat the instrument selection process.
At this point, I have three instruments belonging to this loop as shown below
When you select OK, you are then brought to the P&ID drafting interface, with an instrument in placemen t mode. As soon as you place that instrument and connect it to a pipe run , you are immediately given a second instrument to place. Place that instrument and run its leader like to the first instrument you placed. When that is complete you will see a third instrument to place. Again, place it and run its leader line to the second instrument you placed. You should end up with a configuration similar to that shown below,.
Once, the loop is placed on the P&ID, if you right click on the first instrument, you can select Element Information at the bottom of the fly out for data pertaining to the one instrument OR you can select the second option in the fly out, which is Select Instrument Loop. If you Select Instrument Loop, all three instruments should be highlighted. Right Click again and go to Element Information and you should see all three instruments organized in a logical group.
