Sir,

I want to inquire in SPI ver. 7 if I can copy the JB to the other copy unit using the wiring module?

Because I already created the 1st typical unit so I want to know if I can copy the JB and wiring to the other copy unit?

Hi hans1108,

Probably I am too late to share my experience but nonetheless it worth to read on.

Based on my experience on "Copy Unit" option, you have to be very careful in defining them especially when you have many units in the target plant. My worst nightmare was everytime a copy unit is executed my database grew because it multiplied. I would advise you create a dummy/test domain and do the "copy unit" option where you must have 2-3 other units already created to simulate your project database. Practice and record your steps all the way until you get it right.
