Write scripts quickly for data ingestion and machine monitoring.
Because fwlib32.dll is usually 32-bit, you must use a . This is the most common pitfall.
# Create a FOCAS API object focas_api = focas.FocasAPI()
FANUC FOCAS is a set of dynamic link libraries (DLLs) provided by FANUC. It allows external software to interact with the CNC controller via Ethernet (TCP/IP) or HSSB (High-Speed Serial Bus). Default FOCAS port is 8193
# Define a basic structure for machine status (mirroring ODBST) (ctypes.Structure): = [ ( , ctypes.c_short * ), ( , ctypes.c_short), # Selected automatic mode , ctypes.c_short), # Running status , ctypes.c_short), # Motion status , ctypes.c_short), # M, S, T, B status , ctypes.c_short), # Emergency stop status , ctypes.c_short), # Alarm status , ctypes.c_short), # Edit status Use code with caution. Copied to clipboard Step 2: Establish a Connection cnc_all_clibhndl3 for Ethernet connections to obtain a handle. = ctypes.c_ushort() ip_address 192.168.1.100 # Connect and get handle
The handle h is a short (integer). If you get -8 or -16 errors, check:
: Use a 32-bit or 64-bit Python installation that matches your DLL version to avoid architecture mismatch errors. 2. Implementation with
