Product details

The Siemens 6ES7972-0CA11-0XA0 is a spare-part HMI Adapter V5 for connecting third-party HMI devices to SIMATIC S7-300 or S7-400 via RS-232 or RS-485. Lifecycle stage is mature. This is the exact part for a legacy panel refresh.

RS-232 side connects to the HMI; RS-485 side connects to the S7-300/400 MPI port. The adapter handles the electrical-level translation and protocol framing so a standard serial HMI can read/write data blocks over the Siemens bus.

Frequently asked questions

Will the 6ES7972-0CA11-0XA0 work with a 6ES7522-5FF00-0AB0?

No. The 6ES7522-5FF00-0AB0 is a digital output module for the S7-1500 series, which uses a different backplane bus and connector. The HMI Adapter V5 is designed only for S7-300/400 CPUs.
