Product Description

The 171CCC96020 (171-CCC-960-20) is an integrated CPU and communication adapter for the Schneider Electric Modicon Momentum family. It converts a standard Momentum I/O base into a fully functional distributed controller or standalone PLC node, providing compute logic and networking capabilities for decentralized automation architectures.

Equipped with Modbus TCP/IP over Ethernet and a secondary Modbus serial port (RS-232/RS-485), the 171CCC96020 enables high-speed peer-to-peer communication and integration with SCADA or HMI systems. It features 512 KB flash memory for program storage, battery-backed RAM for data retention, and supports small-to-medium control applications with a compact footprint.

Connectivity and Networking

  • Supports up to 16 simultaneous Ethernet connections, enabling the module to act as a data concentrator for other I/O devices.

  • Bridges legacy RS-485 sensors into modern Ethernet infrastructures with dual Modbus protocol support (TCP/IP and Serial).

  • Compact design reduces footprint while maintaining full networking flexibility for modern plant floors.

Engineering FAQ

Does the 171CCC96020 require a separate power supply module?
No. It draws power through the Momentum I/O base connector. The base itself requires a 24V DC input to power the module and field devices.

Can I perform online program changes with this processor?
Yes. Using compatible software like Concept or Unity Pro, online edits are supported, allowing logic modifications without stopping the process, which is ideal for continuous manufacturing.
