AC800PEC series PPD517A3011 3BHE041576R3011 丨ABB

Key benefits

The AC 800PEC is a modular high-speed control system. The modules are arranged according to the required I/O config uration and the process. CEX Bus Ethernet TCP/IP (Com 1/Com 2) The AC 800PEC I/O modules are connected via optional high-speed point-to-point connections. The AC 800PEC supports up to 36 bi-directional fiber-optic PowerLinks.

Performance

The AC 800PEC excels with a very high processing speed. It provides Fieldbus (AnyBus-S) RS-232/RS-422 (Com 3) Optical ModuleBus Optical links PowerLink the Control Builder M programming tool and to the PECView service tool 

 •RS-232 / RS-422 serial ports for a local process panel and/or service terminal 

 •Very fast analog and digital process I/Os with a typical cycle time of 25 µs 

 •Fast closed-loop control and regular process logic implemented in one controller 

 •Low-speed I/Os with a typical cycle time of 10 ms 

 •Very fast analog/digital conversion and nominal/actual value comparison, directly on the peripheral I/O module. Connectivity The AC 800PEC features outstanding ability to communicate with other control devices: 

 •Two Ethernet ports for connection to a plant control network, other processor modules, 4 

 •Up to two on-board AnyIO ports for ABB Communications Expansion bus (CEX) and AnyBus®-S modules for all common fieldbus types 

 •Up to 36 terminals for optical PowerLinks and ABB S800 optical ModuleBus for cost effective, noise-immune connections to I/O systems and power converters. Modular configuration The modular-design AC 800PEC comes with: 

 •Units mounted onto a DIN rail or equipped for direct wall mounting 

•Hardware and communication modules according to process needs 

•Any combination of fast and slow I/Os, large and small topologies, installed locally and remotely

High performance real-time control

Processor architecture: PowerPC or ARM multi-core processor is adopted to support high-precision real-time control.

Computational power: suitable for complex control algorithms (such as PID and model predictive control)

Task cycle: The typical scanning cycle is as low as 10ms, which is suitable for quick response scenarios.

Redundancy and high reliability

Redundancy support: it can be configured as 1:1 hot standby redundancy (CPU, power supply and communication module can be redundant).

Failover time: < 100ms to ensure uninterrupted operation of the system.

Industrial design: conforming to IEC 61131-2 standard, supporting wide temperature operation from-40 C to+70 C.
