Description
GE 8521-LC-MT is a powerful logic controller.Here is a detailed introduction about it:
I.Product Features
Distributed or centralized design:
The logic controller can be designed as distributed or centralized,and the main control and auxiliary control can coexist on the same network while maintaining functional independence.
Coexistence of main and auxiliary control:
The main controller can listen to safety inputs without interference,reducing the need to replicate field instruments.
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.
High reliability:
The controller contains the main CPU and redundant Ethernet drivers for communicating with network I/O,as well as additional Ethernet drivers for controlling the network.
Multiple I/O modules:
The I/O module consists of three basic components:a wiring board,a wiring board,and an I/O package.The barrier or box wiring board is placed on the wiring board,and the wiring board is installed in the control cabinet on a DIN rail or base.
High network security:
The system has two high-speed Ethernet ports to provide communication security.Each port can be connected to an independent LAN,whose integrity is continuously monitored.If the main port detects a network failure,traffic is immediately switched to another LAN to maintain full communication.
Executable control program:
The control program is saved in non-volatile memory,enabling it to automatically restore the state of the controller after a power cycle.
