2CSS203998R0036 ABB COMM Third-Party Modbus RTU Network Connector

Why Choose the ABB COMM Third-Party Network Connector?

The ABB COMM is a compact third-party Modbus RTU network connector designed for connecting compatible ABB motor operating and automatic-reclosing communication equipment to an external network. Supplied under ABB order code 2CSS203998R0036, it provides the physical connection required when compatible ABB eMOD/AR Modbus equipment is integrated with a third-party Modbus RTU system.

ABB identifies the COMM accessory as a third-party network connector for applications where compatible motor operating devices and autoreclosers communicate through the eMOD/AR Modbus interface. This enables supported ABB devices to be connected either to the ABB InSite architecture or, using this connector, to an appropriate third-party Modbus RTU network.

With a compact 25.5 mm connector format and a unit weight of approximately 0.005 kg, the COMM provides a purpose-designed connection accessory without adding unnecessary bulk to the installation. It is particularly useful where ABB protection-device automation needs to exchange operating information with an external building, energy or supervisory control platform.

Reliable Third-Party Modbus RTU Connectivity

The ABB COMM connector supports installations where compatible motor operating devices and automatic-reclosing equipment need to communicate outside the ABB InSite network. When used with the appropriate eMOD/AR Modbus interface, it provides the connection path required for integration with a third-party Modbus RTU network.

This architecture gives system designers flexibility when incorporating ABB protection-device automation into broader control and monitoring installations. Compatible MOD and AR equipment can therefore participate in external automation or supervisory systems while retaining the dedicated ABB communication interface and connection accessories designed for the application.

Typical Applications

• Third-party Modbus RTU network integration.
• Compatible ABB motor operating device communication.
• Compatible ABB automatic-reclosing device communication.
• Building and energy-management systems.
• Industrial supervisory and automation networks.
• Electrical distribution systems requiring external device communication.
