FANUC FOCAS (Fanuc Open CNC API Specifications) is a specialized communication protocol and a set of library files ( DLLcap D cap L cap L
To get started, you don't need to write low-level protocol code from scratch. Several community-driven libraries simplify the connection: fanuc focas python
cnc_handle = ctypes.c_ushort
Example Snippet:
handle = connect_fanuc(CNC_IP)
if handle:
while True:
status = get_status(handle)
print(f"Machine Status: status")
time.sleep(1)
# Define the ODBPOS structure (used for reading positions)
class ODBPOS(ctypes.Structure):
_fields_ = [
("dummy", ctypes.c_short * 2),
("abs", ctypes.c_long), # Absolute position
("mach", ctypes.c_long), # Machine position
("rel", ctypes.c_long), # Relative position
("dist", ctypes.c_long), # Distance to go

Always ensure your IT department whitelists the Fanuc ports (default 8193) and be cautious when reading/writing parameters, as improper use can affect machine behavior. # Define the ODBPOS structure (used for reading
