Featuring robust hardware, multiple communication options, and user-friendly installation, this unit is built to support ABB’s 800xA Distributed Control System (DCS), ensuring enhanced operational efficiency and uptime. Let’s dive into the key features and benefits of the PM866AK02 processor unit. Advanced Hardware Design and Functionality The CPU board of the PM866AK02 includes a powerful microprocessor paired with a sizable RAM memory for seamless data processing. It also houses a real-time clock, various LED indicators for operational monitoring, an INIT push button, and a CompactFlash interface for data storage and retrieval. These components work in synergy to maintain optimal system performance and help prevent system disruptions. The base plate is equipped with two RJ45 Ethernet ports (labeled CN1 and CN2) for Control Network connectivity, and two RJ45 serial ports (COM3 and COM4) for additional serial communication. COM3 is an RS-232C port designed for modem control, while COM4 is an isolated port for configuration tool connectivity. With the ability to support CPU redundancy, the PM866AK02 offers enhanced availability across multiple functions such as the CEX-Bus, communication interfaces, and S800 I/O. Simplified Installation and Hardware Identity One of the standout features of the PM866AK02 is its simple installation process. Designed with a slide-and-lock mechanism, this unit can be easily attached and detached from DIN rails, making it ideal for rapid deployment in industrial environments. Each base plate comes with a unique Ethernet address, giving every CPU a hardware identity that’s essential for precise network configuration. This unique identifier is visible on the Ethernet address label attached to the TP830 base plate, providing a streamlined setup for operators. Package Components and Redundancy Features The PM866AK02 comes with a comprehensive package that includes: 2 PM866A CPUs for redundancy 2 TP830 Baseplates with a width of 115mm each 2 TB807 ModuleBus terminators for secure bus connection 1 TK850 CEX-bus expansion cable to expand system capacity 1 TK851 RCU-Link cable for additional r...
