The Siemens 6ES7 340-1AH02-0AE0 is a CP 340 communications processor for serial point-to-point links in the SIMATIC S7-300 automation system. Its isolated RS-232C interface connects the controller to communication partners such as PCs, barcode scanners, printers or devices using simple serial protocols. Connection is via a 9-pole Sub-D plug. The supplied drivers support ASCII, 3964(R) and printers. With the 3964(R) procedure, the processor reaches transmission rates up to 19.2 kBaud; ASCII and printer drivers operate at up to 9.6 kBaud. Siemens specifies a maximum cable length of 15 metres for the RS-232C connection. The transmitted signals include TXD, RXD, RTS, CTS, DTR, DSR, RI, DCD and GND. Status LEDs indicate transmitting, receiving and group faults directly on the module. The CP 340 is supplied with 5 V through the S7-300 backplane bus and draws a maximum of 165 mA. Its typical power dissipation is 0.85 watts. The permissible operating temperature ranges from 0 to +60 °C, while the storage range is −40 to +70 °C. With dimensions of 40 × 125 × 120 millimetres, the module occupies one standard slot. According to Siemens, the net weight of this order variant is approximately 0.357 kilograms. 3964(R) telegrams can be up to 1024 bytes long; character frames can be parameterised with 10 or 11 bits. Per program cycle, the standard blocks transfer 14 bytes when transmitting and 13 bytes when receiving. This gives typical serial automation tasks clearly defined data handling. The unambiguous order number supports exact matching with existing hardware configurations, cables and engineering versions, as well as targeted spare-part procurement for installed S7-300 systems.

Up to 19.2 kBaud is possible with 3964(R). The ASCII and printer drivers support up to 9.6 kBaud; the maximum RS-232C cable length is 15 m.
Yes, we provide a 14-day functional guarantee for used items. This means the component must be operational when received.
Please note that the guarantee only applies when the warranty seal is undamaged.
If a defect occurs within 14 calendar days, please contact us in writing. Subject to availability, we will provide a replacement or refund the full purchase price after return.
Further details are provided in the terms and conditions supplied with your quotation.
We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.
Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.
We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.
Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.
As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.
Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.
Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.
For larger order quantities or several items of one type, we can offer individual discounts.
Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.
Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.
The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
