TRICONEX 3008

Brand:TRICONEX

Model: 3008

Status: New/Used

The Triconex 3008 is the "golden bell" in the field of industrial safety control - a triple redundant (TMR) main processor module launched by Triconex (now part of Schneider Electric). It is not a regular PLC, but a "last line of defense" specifically designed for Safety Instrumented Systems (SIS). In the event of dangerous situations such as overpressure, overheating, or combustible gas leakage during the production process, it must ensure 100% reliable and safe shutdown of the equipment.

TRICONEX 3008

TRICONEX3008 has the characteristics of high precision, high stability, and wide frequency range. It has three independent control channels, each of which can independently process input signals and output control signals. This design can increase the reliability and stability of the system, ensuring the normal operation of industrial control systems. TRICONEX3008 is widely used in various industrial control systems, such as petrochemicals, electricity, pharmaceuticals, etc. It can convert various sensor signals on site into digital signals, enabling remote monitoring and control. Meanwhile, it can also be used for data communication and linkage control with other devices.

COM RX receives data from COMM bus.
I0C TX_ - transmits data through the I/O bus.
IOC RX - receives data from the I/O bus.
③ The experience/status port is used to read diagnostic information

physical description
Each main processor operates independently, without sharing a common clock, voltage regulator, or circuit. A Motorola, 32-bit, 50MHz MPC860 is used as the main processor, while another MPC860 manages the I/O and communication subsystems.
Each main processor has a high-speed dedicated bus system called TriBus that performs the following functions:
Communication between processors
Hardware majority voting for all digital input data
Comparison of Variables in a Control Program
TriBus utilizes a completely isolated serial communication channel for communication, with a rate of 25M baud. A direct access storage controller manages synchronization, transmission, voting, and data correction, working independently of the user's application or software execution.
#The 3008 main processor has 16MDRAM (without backup battery) and 32KSRAM, which are used to store user written control programs, SOE1 data, I/O data, diagnostics, and communication buffers. When the external power supply fails, SRAM can store user programs and persistent memory contacts intact for at least six months. TriBus hardware voting circuit periodically verifies the effectiveness of memory.

Sequence of Events Capability (SOE)
The main processor (# 3008 model) and communication module work together to provide SOE capability to the Tricon system. In each scan, the main processor checks for changes in the state of specified discrete variables called events. When an event occurs, the main processor stores the current state and timestamp of the variable in a storage area called a buffer, which is part of the SOE block. You can configure the SOE block using TRISTATION1131 and obtain event data using the SOE event recorder.

外貌描述
每个主处理器独立运行,不共享公共时钟、电压调节器或电路。摩托罗拉32位50MHz MPC860用作主处理器,而另一个MPC860管理I/O和通信子系统。
每个主处理器都有一个名为TriBus的高速专用总线系统,执行以下功能:
一处理器之间的通信
一对所有数字输入数据进行硬件多数投票
一控制程序中变量的比较
TriBus采用完全隔离的串行通信信道进行通信,波特率为25M。直接存取存储控制器管理同步、传输、投票和数据校正,独立于用户的应用程序或软件执行。
#3008主处理器具有16MDRAM(无备用电池)和32KSRAM,用于存储用户编写的控制程序、SOE1数据、I/O数据、诊断和通信缓冲区。当外部电源发生故障时,SRAM可以完整地存储用户程序和持久存储器触点至少六个月。TriBus硬件表决电路定期验证存储器的有效性。
事件顺序能力(SOE)
主处理器(#3008型号)和通信模块协同工作,为Tricon系统提供SOE功能。在每次扫描中,主处理器检查称为事件的指定离散变量的状态变化。当事件发生时,主处理器将变量的当前状态和时间戳存储在称为缓冲区的存储区域中,缓冲区是SOE块的一部分。您可以使用TRISTATION1131配置SOE块,并使用SOE事件记录器获取事件数据。
