Product Introduction
The Siemens 6ES7340-1AH02-0AE0 is a dedicated CP 340 communication processor for SIMATIC S7-300 systems. It provides a reliable RS232C (V.24) interface to connect printers, barcode scanners, and other serial devices. With power supplied via the backplane bus at 5 V DC, this module simplifies wiring and reduces installation costs—an excellent choice for long-term ROI in industrial automation.
Technical Specifications Breakdown
This module draws a maximum input current of 165 mA from the backplane bus. Its power loss is typically 0.6 W and up to 0.85 W, ensuring minimal heat dissipation. The RS232C interface supports transmission rates from 2.4 kbit/s up to 19.2 kbit/s, with a maximum cable length of 15 m. It integrates protocol drivers for 3964(R) and ASCII, and supports HP-Deskjet, HP-Laserjet, IBM-Proprinter, and user-defined printer models. Telegram length is up to 1,024 bytes for both 3964(R) and ASCII protocols. Operating temperature range is 0 °C to 60 °C, and dimensions are 40 mm (W) x 125 mm (H) x 120 mm (D), weighing approximately 300 g.
Industry Applications
The Siemens 6ES7340-1AH02-0AE0 excels in applications requiring reliable point-to-point serial communication. Common uses include:
- Connecting industrial printers for real-time batch reporting in manufacturing.
- Linking legacy RS232 instruments such as weigh scales and barcode scanners for data acquisition.
- Implementing 3964(R) protocol links between S7-300 CPUs and remote terminal units (RTUs) in process control.
By replacing older, less reliable communication modules, this CP 340 reduces unplanned downtime and lowers total cost of ownership—key factors in ROI-driven upgrade projects.
Compatibility & Integration
The Siemens 6ES7340-1AH02-0AE0 integrates seamlessly into SIMATIC S7-300 racks. It supports 3964(R) and ASCII protocols, making it compatible with a wide range of third-party serial devices. The module connects via a standard 9-pin sub-D connector and communicates over the S7-300 backplane bus. No external power supply is needed; all power comes from the 5 V DC backplane. Configuration is performed using the included software package on CD, simplifying setup.
Selection Guide & Purchasing Advice
Before purchasing, verify that your S7-300 CPU supports the CP 340 communication processor and that the slot assignment is correct. Ensure your serial device uses RS232C (V.24) and that the baud rate (up to 19.2 kbit/s) matches your application.
