Schneider Electric 170MCI00100 CANopen Communication Module – Momentum I/O

Schneider Electric 170MCI00100 – CANopen Communication Adapter for Momentum Distributed I/O Architecture

The 170MCI00100 is a dedicated CANopen fieldbus communication adapter engineered for the Schneider Electric Momentum I/O platform. Within a distributed control architecture, this module occupies the communication adapter slot on any Momentum 170-series I/O base and acts as the sole protocol translation layer between the CANopen master controller and the I/O base’s internal backplane bus. Its function is not peripheral — it defines the determinism, cycle accuracy, and diagnostic transparency of every I/O node it serves on the CANopen segment.

Unlike generic gateway devices, the 170MCI00100 is factory-integrated into the Momentum mechanical and electrical ecosystem. The module draws its operating power directly from the I/O base’s 5 VDC internal bus, eliminating external power supply requirements and reducing panel wiring complexity. Hardware-based node addressing via dual rotary switches (range: 1–127) removes the risk of software misconfiguration during commissioning — a critical advantage in multi-node networks where address conflicts cause silent data corruption.

Technical Parameters

Hardware Logical Analysis

The 170MCI00100 implements a two-domain architecture: the CANopen physical layer domain (ISO 11898-2 high-speed CAN transceiver, differential signaling at up to 1 Mbps) and the Momentum backplane domain (proprietary parallel bus connecting the adapter slot to the I/O base’s channel logic). The module’s onboard microcontroller manages the full CANopen NMT (Network Management) state machine — Pre-Operational, Operational, and Stopped states — independently of the master’s scan cycle, which means NMT transitions do not stall the master’s process image update.

PDO Mapping and Cycle Determinism: The module supports both synchronous and asynchronous PDO (Process Data Object) transmission modes. In synchronous mode, I/O data is latched and transmitted precisely on receipt of the CANopen SYNC object, achieving cycle jitter below 1 ms at 1 Mbps baud rate. This is the operating mode required for coordinated multi-axis motion and press-line synchronization. Asynchronous event-driven PDOs are available for alarm and status change reporting without consuming synchronous bandwidth.

EMC Design: The Sub-D9 connector shell is directly bonded to the module’s chassis ground plane, providing a low-impedance return path for common-mode noise induced on the CAN bus cable shield. The CAN transceiver incorporates integrated bus termination detection — the module can be configured as a bus-end node (120 Ω termination active) or mid-segment node (termination disabled) via internal jumper, eliminating the need for external termination resistors at the I/O node. This reduces installation error in field wiring.

SDO and Object Dictionary: The module exposes a full CiA DS-401 object dictionary for digital and analog I/O mapping. SDO (Service Data Object) access allows the CANopen master to read and write configuration parameters — including PDO mapping, transmission type, inhibit time, and event timer — at runtime without interrupting the I/O scan. This enables online reconfiguration of I/O behavior without powering down the node.

LSS (Layer Setting Services): For large network deployments, the 170MCI00100 supports CiA DS-305 LSS protocol, allowing node address and baud rate assignment over the CANopen bus without physical access to the rotary switches. This is operationally significant in panel-mounted or enclosed installations where physical access is restricted after commissioning.

System Integration Benefits

• Zero-wiring adapter installation: The module snaps mechanically and electrically onto the Momentum I/O base adapter slot — no inter-module wiring, no terminal blocks, no additional connectors between the fieldbus interface and the I/O channels.
• Deterministic I/O update cycles: Synchronous PDO mode locks I/O data exchange to the CANopen SYNC period, delivering sub-millisecond cycle jitter for time-critical control loops including servo coordination and press-line sequencing.
• Multi-master interoperability: Full CiA DS-301 compliance means the 170MCI00100 operates as a standard CANopen slave under any certified master — Schneider Electric, Beckhoff TwinCAT, B&R Automation Studio, Lenze, Bosch Rexroth — without vendor-specific configuration tools.
• Online diagnostic transparency: The module continuously reports node health via CANopen Heartbeat and Node Guarding protocols. The master receives real-time node status without polling overhead, enabling the PLC program to react to node failures within one network cycle.
• Scalable network topology: Supports up to 127 nodes per CANopen segment. Multiple 170MCI00100 nodes can be distributed across a single CANopen trunk with standard drop cables, supporting both star and line topologies per CiA 303-1.
• Runtime SDO reconfiguration: I/O mapping, PDO transmission type, inhibit time, and event timers are all writable via SDO at runtime, allowing engineers to tune network behavior under live production conditions without a maintenance window.
• Reduced panel footprint: By integrating the fieldbus interface directly into the I/O base form factor, the 170MCI00100 eliminates the need for a separate DIN-rail-mounted CANopen gateway module, reducing panel space by approximately one module width per I/O node.
• Long-term parts availability: The Momentum 170-series platform has maintained backward mechanical and electrical compatibility across product generations. The 170MCI00100 is compatible with both legacy and current Momentum I/O bases, protecting the capital investment in existing panel infrastructure.
• Commissioning speed: Hardware rotary switch node addressing and auto-detect baud rate capability reduce per-node commissioning time. In networks with LSS support, address assignment can be performed remotely from the master engineering station.
