Important Compatibility Note: For certain legacy devices such as S7-200 PLCs, the adapter may require specific PC/PG interface settings in the programming software. Some users have reported connection difficulties with Microwin and S7-200; verify software configuration before use . For OS updates on HMI panels (e.g., MP277), a different cable (RS232/PPI multi-master) is required—this adapter is not suitable for that purpose .
