One of sps in our firm is built by a good company called avi gmbh. They do their job well and everything went well except their Software.
They built siemens program by their own product named TeCAD, which is very, very, very expensive, even much more expensive than Siemens step7.
Comparing with Step7, TeCAD is much better. But without their TeCAD, we did not do maintenance work well, even though they gave us a step7 project for reference with no symbol table (the symbol is written in stl comments) ,Data block is always no symbol.
So is there some good guy upload the TeCAD software? We just use for maintenance reason and check for some logic.
Great thanks!
