Hi friends...
I have a siemens grinding machine of TGT. Siemens control is 810D, converted to 840 with PCU windows XP having HMI advance software.
Now i am facing a problem where spindle gets off automatically anywhere, i thought its due to some interlock, the PCU HMI advance doesnt have step 7 installed to check the ladder logic of machine.
So I want help how to install and run step 7 in the machine. Machine has USB port and CD ROM.
