9765-210 模拟输入端子板TRICONEX 9765-210广泛的诊断功能可验证每个主处理器以及每个/0模块的运行状况和沟通渠道。暂时性故障由硬件记录和屏蔽多数投票电路。诊断持续故障，热更换错误模块TRICONEX 9765-210或以容错方式运行，直到热更换完成。
主处理器诊断包括以下功能:
●验证固定程序存储器
●验证内存的静态部分
●测试所有基本的处理器指令和操作模式
●测试所有基本的浮点处理器指令
●验证与/0处理器的共享内存接口
●验证每个I/0处理器、通信处理器、本地内存、共享内存
TRICONEX 9765-210接入和RS-485收发器的环回
●验证三时钟接口
●验证三总线接口
每个MP底部的标准25针公头D型连接器(RS-232) 的工作频率为9600位每秒，可由Triconex代表用于诊断分析。RS-232 端口完全隔离(大500VDC)，以提供接地故障保护。
The extensive diagnostic functions of TRICONEX 9765-210 can verify the operational status and communication channels of each main processor and each/0 module. Temporary faults are recorded and blocked by hardware in the majority voting circuit. Diagnose continuous faults, hot replace the error module TRICONEX 9765-210 or run in a fault-tolerant manner until the hot replacement is completed.
The main processor diagnosis includes the following functions:
● Verify fixed program memory
● Verify the static part of memory
● Test all basic processor instructions and operating modes
● Test all basic floating-point processor instructions
● Verify shared memory interface with/0 processor
● Verify each I/O processor, communication processor, local memory, shared memory
TRICONEX 9765-210 Access and RS-485 Transceiver Loopback
● Verify the three clock interface
● Verify the three bus interface
The standard 25-pin male D-type connector (RS-232) at the bottom of each MP operates at a frequency of 9600 bits per second, which can be represented by Triconex for diagnostic analysis. The RS-232 port is fully isolated (up to 500VDC) to provide ground fault protection.
