Industry Applications
The Siemens 6ES7340-1AH01-0AE0 is ideal for upgrading legacy S7-300 systems that require serial communication with printers or remote devices. For example, it can drive HP-Laserjet printers using the ASCII protocol at 9.6 kbit/s. Similarly, in point-to-point data exchange scenarios with 3964 (R) protocol, it achieves up to 19.2 kbit/s, ensuring timely transfer of telegrams up to 1,024 bytes.
Compatibility & Integration
This communication processor integrates seamlessly with the SIMATIC S7-300 series via the backplane bus. It supports 3964 (R) and ASCII protocols, as well as printer drivers for common models. The included configuration CD streamlines parameter setup, while the isolated RS232C interface minimizes interference in industrial environments. Cable runs up to 15 meters are supported, making it suitable for local connections.
Selection Guide & Purchasing Advice
When selecting the Siemens 6ES7340-1AH01-0AE0, verify that your backplane bus can supply 5 V DC with a maximum current of 165 mA. Ensure the RS232C interface matches your peripheral's requirements.
