- Program Download (RS232 and PC Communication)
- Pin connections: 2-3, 4-6, 7-8; Pin 5 is left floating, Pins 1 and 9 are open.
- Connection to the S7-200
One method uses an MPI cable with 6 connectors of model 6ES7922-0BA12-DXA0, connected via a PROFIBUS cable in the middle. This setup offers strong anti-interference performance and is highly recommended.
The alternative option involves direct wiring: pins 2, 3, 5, and 8 are directly connected. It's important to ensure that the communication protocol, address settings, and baud rate are all aligned using the appropriate software.
