Siemens 6DD1682-0CH0 is a subrack belonging to the UR6021 series of the SIMATIC TDC system. Designed as a modular mounting and connection platform to meet high-end industrial automation control requirements, it serves as the core hardware carrier of the SIMATIC TDC multi-processor automation system. Equipped with 21 slots and a VME bus architecture, it integrates replaceable fans and is compatible with GDM 5-row plug connectors. This subrack provides stable installation, high-speed data exchange and reliable heat dissipation support for CPUs, I/O modules, communication modules and other components. It is widely suitable for industrial scenarios with stringent requirements for processing performance and real-time performance, such as metallurgy, energy and large-scale drive control. The product entered the phase-out stage on October 1, 2023, with its PLM status designated as PM400.
Core Parameters
Basic Specifications
The product belongs to the UR6021 subrack product family and features 21 standard slots, including 8 slots with P0 extended backplane bus dedicated to high-speed point-to-point communication between CPU555 modules. The backplane adopts a high-performance 64-bit VMEBUS, which ensures high-speed data exchange between modules. It is compatible with GDM 5-row plug connectors to meet the requirements for stable connection of system signals and power supply.
Heat Dissipation & Power Supply
It is equipped with replaceable fans with monitoring function, which can feed back the operating status of the heat dissipation system in a timely manner and reduce the risk of system failures caused by overheating. The integrated system power interface provides stable power supply for the subrack and all installed modules. In addition, a backup battery slot (compatible with 1 AA lithium battery) is available for power-off retention of critical data.
Physical & Environmental Specifications
With a net weight of 20.5 kg, the product has dimensions suitable for installation in industry-standard cabinets (typical dimensions: approx. 354.9mm × 482.6mm × 343mm). It adopts a closed EMC shielded enclosure, which can effectively resist electromagnetic interference and adapt to the complex electromagnetic environment of industrial sites.
Lifecycle
The Product Lifecycle Management (PLM) status is PM400, which means the product has been announced as discontinued. The discontinuation took effect on October 1, 2023, and most of the products currently circulating in the market are inventory or spare parts.
Functional Features
High-reliability Hardware Design
The enclosed EMC shielded enclosure reduces the impact of external electromagnetic interference on system operation, ensuring stability of data transmission and module performance. Equipped with 4 status LED indicators, it intuitively displays subrack status including power supply, operation and fault. 3 floating fault signal relays can output fault alarm signals in a timely manner, facilitating quick troubleshooting for operation and maintenance personnel. A configurable runtime counter (requires D7-SYS V8.1 or later) supports flexible configuration of parameters such as system operating time.
High-efficiency Data Exchange Capability
The 64-bit backplane bus architecture enables high-speed data exchange between modules, meeting the requirements of SIMATIC TDC system for processing massive real-time data and being particularly suitable for short-cycle control tasks. The extended backplane bus design of 8 P0 slots provides dedicated channels for high-speed communication between CPU modules, improving the overall control response speed of the system.
Convenient Operation, Maintenance & Installation
Configured with auxiliary tools for module installation and removal, it simplifies module replacement and maintenance procedures, reducing O&M difficulty and time costs. The replaceable fan design allows fan maintenance under non-stop or quick-stop conditions, ensuring continuous and stable system operation.
Compatibility & Applications
Module Compatibility
It is compatible with the full range of SIMATIC TDC system modules, including processor modules such as CPU555, various digital/analog I/O modules, and communication modules. The 21 slots allow flexible combination and configuration, meeting the needs of building automation control systems of different scales and functions.
Application Scenarios
It is mainly used in scenarios such as rolling mill control in the metallurgical industry, power dispatching and power generation equipment control in the energy sector, and high-precision drive control of large-scale transmission systems. It provides a stable and reliable hardware operation platform for these complex tasks requiring high data throughput and short control cycles. Meanwhile, its high-reliability design also suits automation control needs in harsh industrial environments such as chemical engineering and building materials.
