Write method + FileInterface delete one .txt

Pioneer

I have a production line composed of 30 SingProcess and 29 buffers alternated. The cycle times in each SingProcess are firstly recorded to a table and then (endsim method) written into a .txt file using the FileInterface object. I all the situations I used worked correctly, whereas now, in this model, it works for all the stations, except for station 11, where instead of writing on the .txt it deletes it. I really can't figure out why it is doing that. Attached there is my model, however I have an Educational Licence and thus I do not know if others can open it. If it is the case I will post the code.

The  data is not written to TS11.txt  file, because

 

there is no data logged in the corresponding TS11 table.

 

If you look to the corresponding m111 entry method,

 

you (accidentally) set the TS10 table instead of TS11.

 

With following code it will work

 

 

 

-- lookup
if eventcontroller.simtime < eventcontroller.startstat 
	return
end

var str :string


str:=?.name +"_" + to_str(@)

	--TS10.writeRow(0,TS10.ydim+1,str)
	--TS10.writeRow(1,TS10.ydim+1,to_str(eventcontroller.absSimtime))

        TS11.writeRow(0,TS11.ydim+1,str)
	TS11.writeRow(1,TS11.ydim+1,to_str(eventcontroller.absSimtime))

 

 

@ model structure

 

I guess you have spent quiete a  long time creating and renaming  30 X (MSx1 + MSx2 +TSx + writex + FileInterfacex) = 150 objects, which all contain the same code.

 

Object orientated  modeling will reduce the 150  objects  to 5 !

 

Therefore I strongly recommend  to simplify and reduce the objects (with same code) in  the model.

 

Tomorrow I'll send you an example on how, which you should follow.

I imagined the problem was something so easy, but I couldn't really find.

I also didn't know about this object orientated modeling in Plant Simulation, seems cool. Thanks again!!

As posted yesterday, I have tuned the model structure (parameters have not been set!)

 

The dedicated methods and tables have been placed into a station class object

 

The stations in the models.frame are all inherited from this class object

 

with  the following improvements:

 

1. objects reduced from 279 to 139  

 

The methods were optimized with :

 

code lines in init method reduced from 62 to 6

 

code lines in reset method reduced from 31 to 1

 

code lines in endSim method reduced from 67 to 29

 

For future simulations with models likes yours, you should

 

use a similiar structure as shown in the attached model.

Yes,with that a lot of time is saved. I think I understood it. Thanks!!

Hi simulator, I just wanted to tell you that I created another model following your indications and it works finely. Thank you very much
