Description

ABB PM866K01 CPU control module

Hardware parameters:
Dimensions: Width 119 mm (measured along the DIN rail, CEX bus contacts protrude an additional 4 mm when not installed), depth 135 mm, height 186 mm (measured vertically, including locking devices).
Weight: Approximately 1.2kg (Package includes TP830 and bus terminal).
Power supply: 24V DC (voltage range 19.2-30V DC), typical power consumption 5.1W, maximum power consumption 8.6W, redundant power supply status input is yes, built-in 3.6V spare lithium battery.

Processor and Memory
Processor: Model MPC866, clock frequency 133MHz, it only takes 0.09 milliseconds to process 1000 Boolean operations.
Memory: Total memory 64MB, available memory for applications 51.389MB, and 4MB of flash memory for firmware storage.

Communication interface:
Ethernet port: The base plate is equipped with two RJ45 Ethernet ports (CN1, CN2), and the Ethernet interface is Ethernet (IEEE 802.3), with a speed of 10Mbit/s and an RJ-45 female connector (8 poles).
Serial ports: Two RJ45 serial ports (COM3, COM4), among which COM3 is an RS-232C port with a modem control signal, and COM4 is isolated and used for connecting configuration tools.

Functional parameters:
Redundancy function: Supports CPU redundancy, implemented through CEX-Bus, communication interfaces and S800 I/O, which can improve system availability.
Real-time clock: Equipped with real-time clock function.
LED indicator light: It is equipped with an LED indicator light to display the status of the module.
INIT button: There is an INIT button, which is used for related initialization operations.
CompactFlash Interface: It features a CompactFlash interface and can be used for expanding storage, etc.
Communication protocol: Hardware based on the best communication connection standard, supporting communication protocols such as Ethernet and PROFIBUS DP.
Performance indicators: The number of applications per controller is 32, the number of programs per application is 64, the number of charts per application is 128, the number of tasks per controller is 32, the number of different cycle times is 32, and the cycle time per application is as low as 1 millisecond. Through the CNCP protocol, the clock synchronization between AC 800M controllers is 1ms. The event queue in each OPC client controller has a maximum of 3000 events. The transmission speed from AC 800M to the OPC server is 36-86 events per second and 113-143 data information per second.
Module bus: The maximum power supply current on the CEX bus is 2.4A. The maximum I/O capacity on the module bus is 96 (single PM866) or 84 (redundant PM866) I/O modules. The scanning rate of the module bus is 0-100ms (the actual time depends on the number of I/O modules).
