Siemens alarm 33: Different programs same no. RS232C (V.24)
SINUMERIK 810/820 legacy alarm · Siemens 810/820
What it means
During read-in over the V.24 port, the received program carries the number of an already stored program but its content differs. With block transfer the received number is also compared against the program number entered in the Automatic basic display. The control refuses storage to prevent overwriting a proven part program.
Likely causes
- Program number reused for different content
- Transmission corruption altering received data
- Wrong file/number selected at the external device
