Hi, I wonder if the incompatibility of IOs modules from previous versions of LOGO with CPU LOGO! 8 is only the question of dowel pins between the bases and there is also a hardware incompatibility. If I break the plastic pin fitting 6ED1055-1CB00-0BA0 module and connect it to the bus LOGO! 8 will be compatible? Or have even acquire 6ED1055-1CB00-0BA2 module? Thank you very much!
