Product Description

The SST-ESR2-CPX-P is an in-chassis module that integrates seamlessly into the CompactLogix backplane. It provides robust and reliable communication, enabling the exchange of data between CompactLogix controllers and various Modbus-compatible devices. This module is particularly useful in industrial automation settings where different communication protocols need to interact.

It comes with built-in LED status lights (OK, STATE, LINK, SPEED, SD, and FAULT) for easy diagnostics. Configuration is handled via a user-friendly console and stored on an included MicroSD card.

Product Parameters

Product Advantages

• Seamless Integration: Fully integrated into Rockwell’s Integrated Architecture, providing an Add-On-Profile (AOP) for easier configuration within RSLogix 5000, significantly reducing commissioning time.
• No Ladder Logic Required: Eliminates the need to write ladder logic for data transfer between the module and the CompactLogix processor, saving significant programming time.
• Versatile Communication: Simultaneously supports both Modbus TCP (Ethernet) and Modbus Serial (RS232/RS485/RS422) protocols, allowing a single module to handle diverse communication needs.
• High Performance: Features a 32,000-word database and supports up to 256 Modbus commands per port, enabling efficient data exchange for large-scale applications.
• Robust and Reliable: Designed for harsh industrial environments, with 2,500V galvanic isolation on all ports to prevent noise transfer and ensure reliable operation. Its high MTBF (181 years) indicates long-term dependability.
• Simplified Configuration & Diagnostics: Comes with a user-friendly configuration console and advanced visual diagnostic tools, making setup and troubleshooting easier.
• Cost and Space Saving: By supporting multiple protocols and a large number of commands on a single module, it can reduce the number of modules required, saving backplane space and lowering overall system costs.
• Fast Data Refresh: I/O data is refreshed every PLC cycle, supporting up to 255 Read/Write cyclic accesses per channel, ensuring fast system response.

Precautions

• Qualified Personnel: Installation, adjustments, maintenance, and all related activities must be carried out by suitably trained personnel in accordance with applicable safety codes and practices.
• Intended Use: Using the equipment in a manner not specified by the manufacturer may impair the protection provided by the equipment.
• Electrical Hazards: Be aware of potential shock, burn, and arc flash hazards. Always follow proper safety procedures, wear appropriate Personal Protective Equipment (PPE), and adhere to all regulatory requirements for safe work practices.
• Limitations:
  • The module does not support integrated motion on EtherNet/IP networks.
  • It does not support ControlLogix redundancy systems.
  • It does not support SIL 2 applications.
  • It does not have email capabilities or EtherNet/IP socket interface.
• Firmware Compatibility: Ensure the module’s firmware is compatible with your CompactLogix controller’s firmware revision.
• Warranty: Be aware of warranty terms, especially when purchasing used or surplus equipment, as manufacturer warranties may not apply.

Product Applications

The SST-ESR2-CPX-P module is ideal for applications requiring robust and versatile communication between Allen-Bradley CompactLogix PLCs and Modbus networks. Common applications include:

• Industrial Automation: Connecting CompactLogix controllers to a wide range of Modbus-compatible devices like sensors, actuators, motor drives, and other intelligent field devices.
• Process Control: Facilitating data exchange in process industries such as oil and gas, water and wastewater treatment plants, chemical processing, and power generation.
• Machine Building (OEMs): Integrating various Modbus devices into complex machinery controlled by CompactLogix PLCs.
• Building Automation: Connecting HVAC systems, lighting controls, and other building management systems that use Modbus protocols to a central CompactLogix controller.
• Concentrator or Gateway Applications: Acting as a data concentrator or protocol gateway to allow devices on different Modbus networks (TCP and Serial) to communicate with a CompactLogix system.
• SCADA Applications: Providing reliable data acquisition from Modbus devices for Supervisory Control and Data Acquisition (SCADA) systems.
