Product introduction：

The ABB PM866 is a high-performance controller module that is part of the AC 800M controller family and offers the following features and functions:
Processor and memory: Includes microprocessor, RAM memory, real-time clock, LED indicator, initialization button, and CompactFlash interface.
Communication interface: The substrate of the PM866 controller has two RJ45 Ethernet ports for connecting to the control network,

and two RJ45 serial ports, one of which is an RS-232C port with the modem control signal, and the other is isolated for connecting to the configuration tool.
CPU redundancy: Support for CPU redundancy for increased availability, including CPU, CEX-Bus, communication interfaces, and S800 I/O.
Installation mechanism: With a unique slider and locking mechanism, the installation and removal process is simplified.
Hardware Identity: All substrates are equipped with a unique Ethernet address that provides a hardware identity for each CPU, which can be found on the Ethernet address label that comes with the TP830 substrate.
Modularity and scalability: Allows for progressive scaling, has IP20 level protection, requires no shell, and can be configured with an 800xA control builder.
Safety certification: With ISA Secure certification and various standards, including EMC certification, some models are also IEC 61508 SIL3 certified.
Performance: The PM866 has high processing power for complex automated Control and monitoring tasks and supports a variety of programming

languages and development environments, such as the IEC 61131-3 standard programming language, as well as ABB’s own Control Builder M and AC 800M
Environmental adaptability: Can operate at operating temperatures from -40°C to +70°C, storage temperature range from -40°C to +85°C, relative humidity from 5% to 95%, no condensation

PM866

The ABB PM866 is a high-performance controller module commonly used in industrial automation systems. Here are some common questions about PM866 and solutions:
​Redundant configuration problems:
​Problems: You may encounter problems when configuring a redundant system for the PM866, such as redundancy units failing to synchronize or standby units failing to take over if the primary unit fails.
Solution: Ensure that both processor units are configured identically and that redundancy parameters are set correctly. When the main processor unit fails, the standby unit should automatically take over, and the switchover time should be less than 10ms. If the backup unit is faulty, it can be replaced during system operation without affecting the running of the primary unit.
Programming and configuration issues:
​Problems: Programming and configuring the PM866 module using ABB’s programming software may be difficult.
Solution: Use ABB recommended programming environments such as Control Builder M and AC 800M, which support multiple programming languages such as ladder diagram, function block diagram, structured text, and more.
Communication interface problems:
​Problem: There may be a communication problem with the Ethernet or serial port of the PM866 controller.
Solution: Check that the network configuration and connection are correct, ensure that isolated ports are used for configuration connections, and verify that the communication protocols supported by the ports are compatible with the system.
Hardware failure problem:
​The CPU board or other hardware components may be faulty.
Solution: Hardware replacement with a simple DIN rail mounting/removal procedure and unique sliding locking mechanism. Ensure that all hardware components, including CPU boards, baseboards, module bus terminators, etc., comply with the required standards and certifications.
Safety feature issues:
​Problems: You may encounter problems implementing security monitoring and protection measures.
The solution: Leverage 800xA’s object-oriented engineering environment and SIL adaptive library to ensure effective support for the entire system safety lifecycle. Use the IEC61131-3 programming language and ensure that engineered systems block downloads if SIL requirements are not met.
Controller upgrade and maintenance issues:
​Issues: Compatibility or scalability issues may occur when upgrading or maintaining the PM866 controller.
The solution: Regularly inspect and update redundant systems and perform necessary maintenance tasks to ensure that the system is always in top condition. At the same time, ensure that all updates and maintenance operations are well documented and that appropriate training is provided to relevant personnel
