Troubleshoot faults that occur during motor starts using the Motor Start Data logger.
Motor Health Report (E Option) "See" how the motor is operating with comprehensive graphs and tables
Front Panel RS232 port for programming and troubleshooting
Optional embedded Ethernet port
Optional Profibus DP/DPV1 or DeviceNet via dedicated port
Multiple Protocols - Modbus RTU, Modbus TCP/IP
A front RS232 port is provided for downloading setpoints and interrogating the relay using the EnerVista™ 369.
Three independent rear RS485 ports offer the customer flexibility and performance for their communication network. The 369 can communicate at baud rates up to 19,200 bps using the industry standard Modbus® RTU protocol. Fiber optic (option F) Profibus interface (option P), DeviceNet (option D), and Ethernet (option E) ports are also available. The optional direct connect RJ45 Ethernet port can be used to connect the 369 to 10 Mbps Ethernet networks. The communication system of the 369 is designed to allow simultaneous communication via all ports.
Using Ethernet as the physical media to integrate the 369 to Local or Wide Area Networks replaces a multidrop-wired
network (e.g., serial Modbus®), and eliminates expensive leased or dial-up connections, reducing operating costs.
The EnerVista™ Suite is an industry leading set of software programs that will simplify every aspect of using the 369 relay. Tools to monitor the status of the motor, maintain the relay, and integrate information measured by the 369 into HMI or SCADA monitoring systems are available. Also provided are the utilities to analyze the cause of faults and system disturbances using the powerful waveform and Sequence of Event viewers that come with the EnerVista™ 369 Setup Software that is included with each relay.

Access Control
Multilin devices and relays are designed with simple but powerful security to enable reliability and compliance for virtually any project or implementation. With support for multi-level permissions and multi-factor supervisory controls, Multilin devices can help you manage the integrity of your system during commissioning, testing, implementation, and beyond. The SR Family provides separate authentication for settings and commands to the system. In addition, as discrete authentications for local and remote access, it also provides a supervisory control factor that can lock or unlock a device for configuration changes and other modifications.
Intrusion Detection
Multilin’s family of protection and control products can also help enable your security perimeter and intrusion detection programs. By providing essential alarming and logging of critical events, Multilin devices can help you detect potential breaches within your system and allow you to respond quickly and effectively. Specifically, unsuccessful access attempts are logged, alarmed, and lead to potential attackers being locked out. This ensures the reliability of your system during questionable activity.control factor that can lock or unlock a device for configuration changes and other modifications.
Motor Settings Auto-Configurator
Automatically generate a complete settings file, eliminating the need to manually program hundreds of individual protection settings
Auditing and Reporting
With the Security Audit Trail reporting feature and support for Event logging of key activities such
as configuration changes, Multilin devices can help ensure device and protection system integrity,
and perform forensic auditing of activities and changes for compliance.
