2.Product Features

Distributed or centralized design:

The GE 8521-LC-MT logic controller supports distributed or centralized design methods,allowing the main control and auxiliary control to coexist on the same network while maintaining their respective functional independence.

Coexistence of main and auxiliary control:

The main controller can monitor safety inputs without interference,thereby reducing the need to replicate field instruments and improving system efficiency and reliability.

Powerful data processing capabilities:

The main processor and I/O modules use a real-time multitasking operating system,and the control software is provided in non-volatile memory and written in a flexible control block language,ensuring efficient data processing capabilities.

High reliability:The controller contains a main CPU and redundant Ethernet drivers for communicating with network I/O,as well as additional Ethernet drivers for controlling the network,which improves the stability and reliability of the system.

Multiple I/O modules:Supports a variety of input/output modules to connect sensors and actuators to monitor and control various devices in the system.The I/O module consists of three basic components:a terminal block,a terminal block,and an I/O package,which is convenient for users to select and configure according to actual needs.

High network security:The system has two high-speed Ethernet ports to provide communication security.Each port can be connected to an independent LAN and its integrity is continuously monitored.If the main port detects a network failure,the traffic will immediately switch to another LAN to maintain full communication.

Programmability and flexibility:Supports flexible programming methods,allowing engineers to define control logic using different programming languages​​(such as ladder diagrams,structured text,function block diagrams,etc.).At the same time,the control program is saved in non-volatile memory,which can automatically restore the state of the controller after a power cycle.

Fault detection and alarm:With fault detection and alarm functions,it can monitor the abnormality of the system status in real time and remind operators to take corresponding measures.

Online monitoring and diagnosis:

With online monitoring and diagnosis functions,it supports maintenance and troubleshooting,reducing system downtime and maintenance costs.
