Strange reaction to newly created symbol.

[testsubject]

After I insert this symbol, it takes forever to do an edit or retag on the symbol. And when I say forever, I meant 3 minutes.

After this is over, I check the text window and see these lines which I never noticed before:

Command:  _.ZOOM
Specify corner of window, enter a scale factor (nX or nXP), or
[All/Center/Dynamic/Extents/Previous/Scale/Window/Object] <real time>: 1X
Command: _.ZOOM
Specify corner of window, enter a scale factor (nX or nXP), or
[All/Center/Dynamic/Extents/Previous/Scale/Window/Object] <real time>: _PREV
Command:
 Searching for PLC address. . ._.ZOOM
Specify corner of window, enter a scale factor (nX or nXP), or
[All/Center/Dynamic/Extents/Previous/Scale/Window/Object] <real time>: 1.0X
Command: _.ZOOM
Specify corner of window, enter a scale factor (nX or nXP), or
[All/Center/Dynamic/Extents/Previous/Scale/Window/Object] <real time>: _PREV
Command:

The one that gets me is the "Searching for PLC Address" line. This is not  PLC part. It is going to be a component that represents a slipring assembly. If I check a different component, the edit dialog box pops up like normal. The only real difference from my other components is that I am using WD_JUMPERS to tie the terminals together left to right.

I did delete and rebuild the project's scratch database so that is not it.

Any clues??

Bob, I tested your symbol and it seems to work just fine.  I checked the WD_JUMPERS attribute value and all looks in order.  In fact I tested that the wire numbers carried through from left to right.  There is no delay when I insert or edit and I see no reference to searching for PLC address.  The program expects a symbol name to begin with PLCIO if it is to be treated as a PLC.

Just a thought.  Have you purged all previous occurrences of the symbol from your drawings, or used Update Block, just to be sure there are no leftover problems from a previous insertion. I know that when I create symbols this large, it sometimes takes a but of tweaking until they are perfect.  I have very similar symbols I use for Flex I/O.  I also use the WD_JUMPERS attribute to internally jumper the DC+ and DC common.

I am using ACE 2012 with Windows 7 64-bit.

Thanks for trying Doug.

I did try all the things you suggested before I posted. It is really strange. The funny thing is that I have other symbols that are very similar to this one and I have no problems with them.  I was hoping that I just overlooking something. That whole "Searching..." thing is making me wonder what is going on. I will try again on Monday and see if there is something I am missing. Sometimes a couple of days distance causes things to become clearer...

Hi Bob.

It got it to use more than 30 seconds to insert your component, when this checkbox was checked (Not exactly 3 minutes, but it might be your problem. Many connection points, many wires to check for an I/O):

THL,

That was it! This was a very subtle problem.

Sometimes it is good to throw it up for everone to see. It can be hard to notice something like this if you are too close to the problem.
