IC695CMU310

Description

Product Overview

The IC695CMU310 is a high-performance communication module belonging to Emerson’s RX3i PLC series, designed to serve as a versatile connectivity hub for industrial automation systems. As a key component of the RX3i platform, IC695CMU310 bridges the gap between the PLC CPU (such as the IC695CPU315-AA) and various industrial devices, enabling seamless data exchange across diverse networks.

This module is engineered to support multiple communication protocols, making it ideal for environments where interoperability between different automation components is critical—from legacy serial devices to modern Ethernet-based systems. IC695CMU310 combines rugged industrial design with flexible configuration options, ensuring reliable operation in harsh conditions while adapting to evolving network requirements. Its ability to integrate with both new and existing infrastructure solidifies its role as a cost-effective solution for enhancing connectivity in mid-to-large-scale automation projects.

Technical Specifications

Main Features and Advantages

Multi-protocol support: IC695CMU310 stands out for its ability to handle Modbus RTU, Modbus TCP/IP, Ethernet/IP, and PROFINET protocols simultaneously, eliminating the need for separate communication modules. This versatility allows it to connect the RX3i PLC to a wide range of devices—from legacy sensors using RS-485 to modern HMI panels and third-party PLCs via Ethernet—simplifying system architecture and reducing hardware costs.

Dual Ethernet and RS-485 ports: Equipped with 2 Ethernet ports and 2 isolated RS-485 ports, IC695CMU310 enables redundant communication paths, critical for minimizing downtime in mission-critical applications. For example, one Ethernet port can connect to a SCADA system while the other links to a local HMI, ensuring data flow continues even if one network fails. The isolated RS-485 ports prevent ground loops, a common issue in industrial environments with long cable runs.

Easy configuration and integration: IC695CMU310 is fully compatible with Emerson Automation Studio, allowing engineers to configure protocols, set baud rates, and map data points through a user-friendly interface. This reduces setup time compared to manual programming, while pre-built driver libraries for common industrial devices streamline integration with equipment from brands like Siemens, Allen-Bradley, and Mitsubishi.

Rugged industrial design: With an operating temperature range of -40°C to +70°C and 2.5 kV AC isolation between ports, IC695CMU310 thrives in harsh environments—from freezing cold warehouses to high-temperature chemical plants. Its robust construction resists vibration, EMI, and voltage spikes, ensuring consistent performance in conditions that would disrupt less durable communication modules.

Application Field

The IC695CMU310 is a versatile solution for industries requiring seamless communication between diverse automation components. In manufacturing, it connects RX3i PLCs to robotic arms (via PROFINET), conveyor systems (via Modbus RTU), and MES servers (via Ethernet/IP), enabling real-time production monitoring and process optimization. A U.S.-based automotive parts plant, for instance, uses IC695CMU310 to synchronize 15 robotic welders with a central SCADA system, reducing data latency by 30% and improving weld quality consistency.

In water and wastewater treatment, IC695CMU310 links PLCs to distributed sensors (measuring pH, flow, and pressure via Modbus RTU) and remote control valves (via Ethernet/IP), ensuring efficient management of treatment processes. A municipal plant in Europe leverages the module’s redundant ports to maintain communication with pump stations during network outages, preventing overflow incidents and reducing maintenance costs by 25%.

Energy sector applications benefit from IC695CMU310’s ability to integrate with both legacy and modern equipment. A solar power farm uses the module to connect RX3i controllers to inverter systems (via Modbus TCP/IP) and weather stations (via RS-485), optimizing energy output by adjusting panel angles based on real-time weather data. Its rugged design withstands outdoor conditions, ensuring reliable operation even in extreme temperatures.

Installation and Maintenance

Pre-installation preparation: Ensure the RX3i rack (e.g., IC695RACK203) has an available slot and that the CPU firmware is compatible with IC695CMU310 (version ≥v4.0). Verify that the installation environment meets the module’s temperature and humidity requirements (-40°C to +70°C, 5%-95% non-condensing). Power off the rack before installation, then align IC695CMU310 with the slot guides, slide it in until fully seated, and secure with front-panel screws (torque to 8 N·m). Connect Ethernet and RS-485 cables to the appropriate ports, ensuring shielded cables are grounded to the rack to prevent interference.

Maintenance recommendations: Conduct daily visual checks of IC695CMU310’s status LEDs—ensure power (green) and communication activity (flashing green) indicators are active, with no red fault LEDs. Weekly, use Emerson Automation Studio to monitor protocol error rates (target <0.1%) and network latency. Every 3 months, inspect cable connections for tightness and corrosion, especially in humid environments, and clean port connectors with compressed air. Update the module’s firmware annually using Automation Studio, following Emerson’s compatibility guidelines. In case of communication failures, use the software’s diagnostic tools to isolate issues (e.g., port errors, protocol mismatches) before replacing components.
