Product description

The permissible operating temperature ranges from 0 to +60 °C, while the storage range is −40 to +70 °C. Documented identifiers and values: 6ES7; 340-1AH02-0AE0; 340; SIMATIC-S7-300; RS-232C; 3964; 3964; 19; RS-232C; 15 m; S7-300; 5 V; 165; 0.85 W; 60; 40; 125; 120 mm; 0.357 kg. The CP 340 is supplied with 5 V through the S7-300 backplane bus and draws a maximum of 165 mA. 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. 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. Its typical power dissipation is 0.85 watts. 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. 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. Buyers can compare these product details with the designation and technical requirements in their own application documents. The information covers device classification, configuration details, electrical data, interfaces and mechanical attributes where listed.

Which protocols does the Siemens 6ES7 340-1AH02-0AE0 support?

The product data lists the documented identification and technical characteristics for this component. Documented identifiers and values: 340; 3964; RS-232C.

What maximum transmission rate does the CP 340 reach?

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.

What applies if an item develops a defect within 14 days?

For the condition categories “Used, removed from an installation” and “New, old stock”, the contractual 14-day right of return in the event of a defect applies. The defect must occur within 14 calendar days after delivery and be reported in text form within the same period.

In particular, the REHA tamper-evident seal must remain fully intact and our RMA approval is required before return. In an accepted case, we decide between replacement and refund. Details in Section 11 of the Terms.

Which shipping methods and delivery times are available?

The shipping method, shipping cost and estimated delivery time are confirmed for the specific order. Depending on the item, destination and urgency, we can check parcel, express or freight shipping as well as collection.

A delivery date is binding only if we expressly confirm it as binding.

Which payment terms apply?

The payment terms stated in the checkout or order confirmation apply. Depending on the order and customer, payment is made in advance or against invoice.

International deliveries and deliveries to new customers are generally made against advance payment unless we expressly confirm another payment arrangement.

Can I return an item ordered incorrectly or found incompatible?

No. There is no general B2B right of return, exchange, cancellation or withdrawal. Incorrect or duplicate orders and a lack of suitability or compatibility with the customer’s installation are not covered by the contractual 14-day right of return in the event of a defect. Details in Section 12 of the Terms.

Can I request individual pricing for several items?

You may request an individual quotation for several items or larger quantities. We then check availability and pricing for the specific requirement; there is no entitlement to a quantity discount. Open the quick enquiry.

Do you also purchase industrial spare parts?

Yes. You can offer us automation and drive components for purchase. Please provide complete type numbers, quantities, condition details and photographs where possible.

After review, we will tell you whether a purchase is possible and on which terms. Learn more about selling industrial stock.
