Sourcing and Integrating the ABB 1MRK002311-AAR02: A Practical Guide

Procuring and integrating a specialized component like the ​ABB 1MRK002311-AAR02​ communication module requires careful planning. Whether you are upgrading an existing relay or specifying a new system, this guide provides a practical, step-by-step approach to sourcing the right module, ensuring compatibility, and successfully integrating it into your protection and control system.

Step 1: Verification and Compatibility Check

The first and most critical step is to ensure the module is compatible with your specific relay.

​1. Identify Your Relay Model​

The 1MRK002311-AAR02 is designed for the ​RELion​ product line. You must know the exact model of your relay (e.g., RET 613, REF 615, REJ 603). This information is found on the nameplate of the device.

​2. Check Hardware Compatibility​

Not all communication modules are compatible with all relay versions or hardware versions (HWV). Consult the official ​ABB product manual​ for your specific relay model. The manual will have a list of compatible plug-in modules. You can also contact ABB technical support or a certified ABB distributor with your relay's model and serial number for confirmation.

​3. Verify Firmware and Software Requirements​

The functionality of the communication module is tied to the relay's firmware and the engineering software used to configure it. Ensure that:

• Your relay's ​firmware version​ is compatible with the advanced functions of the communication module. An upgrade might be necessary.
• Your engineering team has access to the correct version of ​ABB's PCM600​ engineering software with the appropriate IED Packages (Device Description files) for your relay and the communication module.

Step 2: Sourcing and Procurement

​1. Source from Authorized Distributors​

To avoid counterfeit or obsolete components, always purchase the ​1MRK002311-AAR02​ from an ​authorized ABB distributor or directly from ABB. Counterfeit modules can fail unpredictably and pose a serious risk to system reliability and safety.

​2. Understand Lead Times​

This is a specialized industrial component. Check with the supplier regarding lead times to ensure it aligns with your project schedule.

​3. Consider Lifecycle Status​

Check the product's lifecycle status on the ABB website. While the 1MRK002311-AAR02 is a widely used module, understanding its status (Active, Classic, etc.) helps in planning for future spares and long-term support.

Step 3: Physical Installation and Configuration

​Warning:​​ Installation and configuration should only be performed by qualified personnel trained in electrical safety and protection systems.

​1. Safe Installation Procedure​

1. ​De-energize the Relay:​​ Completely isolate the relay from all AC/DC power sources.
2. ​Install the Module:​​ Carefully insert the communication module into the designated slot on the relay. It is designed as a plug-in unit and should fit securely without forcing it.
3. ​Re-energize:​​ Restore power to the relay.

​2. Software Configuration with PCM600​

The physical installation is only half the job. The communication capabilities must be enabled and configured in software.

1. ​Connect to the Relay:​​ Connect your engineering laptop running PCM600 to the relay's service port or via the new Ethernet network.
2. ​Read the Relay Configuration:​​ Upload the current configuration from the relay.
3. ​Configure Communication Parameters:​​ In the PCM600 tool, navigate to the communication settings. Here, you will need to configure:
   • ​IP Address, Subnet Mask, Gateway:​​ For the Ethernet interface.
   • ​IEC 61850 Parameters:​​ Setting the Logical Device (LD) name and configuring the data set and reporting controls.
   • ​GOOSE Publishing/Subscribing:​​ Defining which signals are sent (published) and which are received (subscribed) for the protection schemes.
   • ​DNP3 or IEC 60870-5-103 Settings:​​ If these protocols are used, the points list and communication layers need to be mapped.
4. ​Download and Test:​​ Download the new configuration to the relay. Thoroughly test the communication by pinging the device, checking data points in the SCADA system, and simulating GOOSE messages.

Conclusion

Integrating the ​ABB 1MRK002311-AAR02​ module is a straightforward process when following a methodical approach. Success hinges on upfront verification of compatibility, sourcing from authorized channels, and precise configuration using the correct engineering tools. By following this guide, you can effectively enhance your protection relays with advanced communication capabilities, ensuring they meet the demands of a modern automated power system.
