Cause: The receiving device did not get data before its internal timer expired.
In the world of Computer Numerical Control (CNC) manufacturing, data transfer reliability is not just a convenience—it is a necessity. For decades, Siemens has been a titan in the industrial automation space, producing the SINUMERIK line of CNC controllers. While modern machines now feature USB ports, Ethernet, and cloud connectivity, a vast installed base of legacy machines (Series 810, 820, 840D, 802D, and 880) still rely on a robust, simple protocol: .
Usually set to "Even" for Siemens systems, though "None" is used in specific binary transfers. Stop Bits: Standard configuration is 1 or 2 stop bits.
Usually set to 7 (if parity is Even) or 8 (if parity is None). Stop Bits: Standard setting is 1 or 2 . Siemens Winpcin
Click on Receive File in the software interface. Select or create the destination folder and define the file name (e.g., NC_BACKUP.ARC ). Click OK or Start . WinPCIN will enter a waiting state.
What is the (e.g., 810G, 840D PL, 828D)?
: Essential for taking machine backups to prevent data loss from battery failure or hardware replacement. Cause: The receiving device did not get data
While modern Sinumerik controls (like the 840D sl and One) rely on Ethernet networks, USB interfaces, and advanced software like Access MyMachine, WinPCIN remains indispensable for legacy and classic hardware. It is the primary tool used for: Sinumerik 802D / 802C / 802S Sinumerik 810T / 810M / 820 (Older GA1 and GA2 variants) Sinumerik 3T / 3M legacy systems Core Functionalities and Key Features
: With Siemens WinPCin, data management and analysis become significantly more accessible. The software enables the collection and processing of data from various sources within the industrial environment. This capability supports advanced analytics, facilitating better decision-making and optimization of industrial processes.
Connect a null-modem RS-232 cable to the of the PC. While modern machines now feature USB ports, Ethernet,
Frequently caused by improper cable wiring (incorrect RXD/TXD connection) or mismatched baud rates.
Ensure the machine is in the correct mode (e.g., stopping the program execution) before initializing the backup.
Set to RTS/CTS (Hardware) or XON/XOFF (Software). Siemens systems generally prefer hardware handshaking for archive files to prevent data overflow. How to Perform a Data Backup (CNC to PC) To pull data out of the machine for an archive backup:
Click on and set the COM port, Baud Rate (e.g., 38400), 8 Data Bits, Even Parity, and 1 Stop Bit. Save the configuration. Step 2: Preparing WinPCIN for Reception Click the Receive button (or Save File option) in WinPCIN.
Match the baud rate, parity, and data bits to your CNC machine's settings. : Navigate to the Services menu on your SINUMERIK controller. Select Data In to put the machine in a receiving state. Send the File : In WinPCIN, select Send Data and choose your program file.
