Some hints : 1st Don't use CNC program name starting with digit such as '11, 22.' Use at least 3 letters. if you have MMC103 or PCU50, there is HD to store the program. How long ? the memory is full or not full, check HMI display. I don't know why you can only transfer 6 CNC programs.

One thing I am sure-You cannot use MPI port, don't try it. off cause you can use any other sw to transfer. Normally Siemens suggest use PC or Laptop with RS232 port or USB convert to RS232, By CAD/CAM and post process ? and what device you use to transfer what software you use Such as you have 810D (not 810M or T old CNC), what kind of HMI you have -MMC103 or MMC100.2 PCU50 or PCU20.Īnd how can you get CNC programs. Hi, Sir, if you need better help, you should let me know you m/c in detail. I thought, maybe i must use MPI port (please see attached picture)for sending NC program to machine but one of my friend told me it may hurt your PLC ,

Note : the header of the these program that machine accept it is very special, it is not Gcode, it is like binary code that only CNC machine know it and when i copy and past it in new program, this machine doesn't accept

Yes, and i use port 24.v now but the main problem is that i can only send 6 program to this machine and if i want to send a new program i have two problem :ġ- this machine only accept 6 program with specified name like 11, 55, 77, 44and if i want to send a new program to it i need to replace the new G code to one of these files and then send it againĢ- these files are used only for specified program capacity, i think because if the line of my new program be more that 70 lines it must be replaced in the for example file with name 55 and if the new NC program be more than 120 lines it must be write in for example program with number 11
