The IC660PRD021 is a redundant Profibus DP communication module within GE Fanuc's (now Emerson Automation) VersaMax I/O platform. It enables VersaMax I/O systems to communicate with Profibus DP networks, allowing them to integrate seamlessly with Profibus-based control systems and devices. In addition, it provides redundant communication capabilities to ensure high availability and fault tolerance in critical applications.

The main features of the redundant IC660PRD021 Profibus DP communication module are:

Profibus DP Slave device: The IC660PRD021 operates as a Profibus DP slave device and is capable of receiving and responding to Profibus DP messages from the Profibus DP master device.

Redundant communication channels: It has two redundant Profibus DP communication channels that provide backup in case one channel fails.

Automatic failover: If the main channel fails, the module automatically switches to the standby channel, ensuring uninterrupted communication with the Profibus DP network.

GSD file support: It comes with a GSD (Device Description) file that provides detailed information about module configuration and parameters and can be easily integrated with the Profibus DP master device.

Up to 127 slave stations per network: This module supports up to 127 slave devices on a single Profibus DP network, allowing a large number of devices to be connected.

Baud rate selection: The baud rate can be selected between 9600 bps and 12 Mbit/s to suit various network requirements.

Diagnostic leds: Status leds (INT PWR LED, OK LED, TX/RX LED, and ERR LED) indicate the presence of input power, normal module operation, Profibus DP network communication status, and communication errors, respectively.

Application of IC660PRD021 Profibus DP communication module with redundancy function:

Critical control systems: The IC660PRD021 is commonly used in critical control systems that require uninterrupted communication, such as manufacturing, power generation, and transportation applications.

Process control systems: It can be used in process control systems where redundancy is critical to maintaining process integrity and preventing downtime.

Security system: This module is suitable for security systems where communication failures may cause serious consequences, ensuring the safety of personnel and equipment.

Infrastructure control systems: It can be used in infrastructure control systems, such as building automation systems and traffic control systems, where redundancy is important to maintain system uptime and reliability.

Precautions for using IC660PRD021:

Redundancy requirements: Evaluate the redundancy requirements of the application to determine if the dual Profibus DP communication channel of the IC660PRD021 is required.

Network topology: Consider network topology and cable length to ensure reliable communication and minimize signal reflection.

Terminating and grounding: Implement appropriate terminating and grounding techniques to minimize noise and interference on the Profibus DP network.

Expert Support: For specialized configuration, installation, or troubleshooting tasks, seek help from a qualified GE Fanuc (now Emerson Automation) personnel or authorized resellers.
