I have a problem with a cnc machine using step 5 siemens plc, the problem is that the machine doesnot recognise the plc, so i need to know the software to be installed on the pc inorder to be able to connect to the plc, i mean it`s name, a link to download if possible, i ask also the schematic configuration of the communication cable between the pc and the plc, is it A must to use a pg or i can use a normal laptop with usb to serial converter.
thanks at all..
