Schneider 171CCC96020 Overview
The Schneider 171CCC96020 is a processor adapter module from the Modicon Momentum series. It serves as the central processing unit for distributed automation applications. This module integrates Ethernet communication and I/O handling in a compact design. Engineers rely on it for reliable data processing in industrial environments.
This module operates on a 50 MHz clock frequency, ensuring rapid execution of control logic. It supports both flash memory and RAM, providing 512 KB and 544 KB of storage respectively. With a 16-bit word length, it handles data efficiently. The scan time of 0.3 ms per kilobyte enables fast response to process changes.
Key Technical Specifications
The 171CCC96020 features one Ethernet port and one I/O bus port. This dual-port architecture allows for seamless integration with existing networks. The Ethernet port supports Modbus TCP messaging and I/O scanning. The I/O bus port connects directly to Momentum I/O bases, simplifying wiring.
For I/O capacity, the processor handles up to 8,192 bits of discrete I/O. Register I/O capacity reaches 26,048 words. This makes it suitable for medium-sized control systems. The module also supports up to 128 I/O words per drop (using Concept software), or 80 words with ProWORX.
Memory and Processing
The module includes 18 KB of program memory for LL984 logic and 24 KB for data storage. This allocation supports complex control routines. The processor uses an x86-based architecture, ensuring broad compatibility with legacy and modern programming tools. Supported software includes Concept V2.6, Modsoft V2.5 and later, ProWORX NxT V2.0, and ProWORX 32.
Environmental and Physical Specifications
The 171CCC96020 operates in ambient temperatures from 0 to 60°C. It withstands storage temperatures from -40 to 85°C. The module tolerates relative humidity of 5 to 96% without condensation. It also resists shocks up to 15 gn peak and vibrations of 1 gn. These ratings make it suitable for harsh industrial settings.
Weighing only 0.42 kg, the module is lightweight and easy to mount. It draws power from the Momentum I/O base via a 5.0 V DC supply. The Lexan housing provides durability and protection. Certifications include CE, UL, cUL, and FM Class 1 Division 2, ensuring compliance with international standards.
Best Practices for Implementation
When deploying the 171CCC96020, verify that your I/O configuration does not exceed the processor limits. Plan your network topology to take advantage of the dual-port design. Use the Ethernet port for HMI or SCADA connectivity, and the I/O bus for local expansion. Regularly monitor the module's temperature and humidity to maintain optimal performance.
For programming, select the appropriate software suite based on your existing infrastructure. Concept and ProWORX offer robust features for configuring and diagnosing the module. Ensure your firmware is up to date to access the latest features and fixes.
In summary, the Schneider 171CCC96020 is a versatile processor adapter module that balances performance and reliability. Its Ethernet capabilities and ample memory make it a solid choice for modern automation projects. By understanding its specifications, you can integrate it effectively into your control systems.
