It supports high-speed data transfer up to 187.5 Kbps and operates reliably in extreme industrial conditions (-20°C to +75°C). Compatible with STEP7 V5.2+ and Micro/Win 4.0+, it enables hassle-free, long-distance communication up to 1000 meters, making it the essential tool for professional automation engineers seeking stable, interference-free programming. ## Description Parameter: Model: 0CB20 compatible (6ES7 972-0CB20-0XA0) Length: about 4.5m Interface: USB-9 pin male System: Perfect support for XP WIN7 VISTA Complete set: packing box + adapter + standard wiring Purpose: Support PPI/MP and DP multi-master communication, used for Siemens S7200/300/400 and Siemens department touch (TP170/177/270, OP25/35/77, MP177/270/277B, etc.) Isolation advantages: full-signal photoelectric isolation, strong stability, can monitor S7-300 online, data transmission block, generally used in the field, because there are usually inverters, modules and other equipment on the field, interference will occur during start and stop, which will affect data Transmission, the isolation type must be selected at this time. About the driver: When your Siemens 300 programming software is V5.5, no driver is required, no serial port generation is required, and USB is directly selected. Whether it is communicating with S7-200/300/400 PLC, please be sure to install Siemens 300 programming first. ## Features - PC adapter USB is the optoelectronic isolated adapter for industrial design. There is anti-surging& anti-lightning protection for the USB and RS485 interface. It support hot plug. Its suitable for S7-300/400/200 series PLC. In particular, it applies to the strong interfere industrial scene and the safeguard in the circuit guarantees the safely running of the system. - 7972-0CB20-OXAO is optical isolation for industrial design in USB port and RS485 ports are equipped with surge protection and lightning protection circuitry for Siemens S7-300 / 400 and S7-200 series PLC full range PLC. Particularly suitable for interferences fragile industrial field communication port, the circuit in a variety of protective measures to ensure the safe operation of the system. - Photoelectric isolator: The device is also called a photocoupler, or optocoupler for short. Optical couplers use light as a medium to transmit electrical signals. It has a good isolation effect on input and output electrical signals.The main advantages of optocouplers are: signal transmission in one direction, electrical isolation at the input end and output end, the output signal has no effect on the input end, strong anti-interference ability, and stable operation. - Features and technical indicators: software version STEP7 V5.2 and above, STEP7 Micro /Win 4.0 and above. MPI baud rate 19.2Kbps, 187.5 Kbps. PPI baud rate 9.6Kbps, 19.2Kbps, 187.5Kbps. The MPI port automatically adapts to the communication rate of 19.2Kbps and 187.5Kbps, 500Kbps, 1.5M Kbps DP master communication. - Working temperature: -20-+75°C, long-distance communication, communication distance 1000m (RS485 end, when the baud rate is 187.5Kbps) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B82MPLB7 | | Best Sellers Rank | #36,436 in Computers ( See Top 100 in Computers ) #2,556 in USB Cables | | Brand Name | DCYNXC | | Cable Type | USB | | Color | Black | | Compatible Devices | S7-200/300/400 PLC | | Compatible Phone Models | No Compatible Phone Models | | Connectivity Technology | USB | | Connector Gender | Male-to-Male | | Connector Type | Optical, USB, USB Type C | | Customer Package Type | rigid box | | Customer Reviews | 4.5 4.5 out of 5 stars (6) | | Data Transfer Rate | 187.5 Megabits Per Second | | Frequency | 187.5 KHz | | Indoor Outdoor Usage | Outdoor | | Item Length | 4.5 Meters | | Item Shape | Round | | Item Weight | 0.36 Kilograms | | Manufacturer | DCYNXC | | Model | 0CB20 | | Model Name | S7-200/300/400 | | Number of Items | 1 | | Number of Pins | 9 | | Other Special Features of the Product | Long Range | | Outer Material | Braided | | Recommended Uses For Product | Industrial automation programming and system maintenance | | Unit Count | 14.7634 Feet | ## Product Details - **Brand:** DCYNXC - **Cable type:** USB - **Compatible devices:** S7-200/300/400 PLC - **Connector type:** Optical, USB, USB Type C - **Special features:** Long Range ## Images ![Compatible with Siemens PLC Programming Cable S7-200/300/400 Data Download Line 6ES7972-0CB20-0XA0,USB/MPI PC Adapter USB Cable for Siemen S7-200/300/400 PLC MPI/DP/PPI Programming Cable 16ft - Image 1](https://m.media-amazon.com/images/I/61VsNrj0e5L.jpg) ## Frequently Bought Together - DCYNXC Compatible with Siemens PLC Programming Cable S7-200/300/400 Data Download Line 6ES7972-0CB20-0XA0,USB/MPI PC Adapter USB Cable for Siemen S7-200/300/400 PLC MPI/DP/PPI Programming Cable 16ft - Avanexpress PLC Micrologix Cable USB Interface Compatible PLC Micrologix 1000, 1200, 1400 Series with USB-1761-CBL-PM02 8 Pin Round Aapater --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/506720066-compatible-with-siemens-plc-programming-cable-s7-200-300-400](https://www.desertcart.at/products/506720066-compatible-with-siemens-plc-programming-cable-s7-200-300-400) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-11*
