The main modules all adopt large-scale or very large scale integrated circuit,a large number of switching actions are completed by contactless electronic memory,I/O system is designed with perfect channel protection and signal conditioning circuit.
Shielding-USE conductive and magnetically conductive materials to shield major components such as power transformers,cpus and programmers to prevent external interference.
Filtering-The power supply system and input lines are filtered in various forms,such as LC orπ-type filtering network,to eliminate or suppress high-frequency interference,and also to weaken the interaction between various modules.
Power supply Adjustment and protection--The+5V power supply required by the core component of the microprocessor is filtered by multiple stages and adjusted with an integrated voltage regulator to adapt to the fluctuations of the AC grid and the influence of overvoltage and undervoltage.
Isolation--between the microprocessor and I/O circuit,photoelectric isolation measures are used to effectively isolate the electrical connection between the I/O interface and the CPU to reduce faults and misoperations;Each I/O port is also isolated from each other.
Use a modular structure-this structure facilitates short-term repair in case of failure.Once a module is found to be faulty,it can be quickly replaced to restore the system to normal work;It also helps to find the cause of the fault faster.
·Software measures:3500/53 133388-01
Has a strong self-inspection and protection function.
Fault DETECTION-The software regularly detects the external environment,such as power failure,undervoltage,low voltage of lithium batteries and strong interference signals.In order to timely processing.
Information PROTECTION and recovery-does not destroy the PLC internal information when the occasional fault condition occurs.Once the fault condition disappears,it can return to normal and continue the original program work.Therefore,PLC in the detection of fault conditions,immediately put the current state into the memory,the software with the memory closed,prohibit any operation on the memory,in order to prevent the storage information is washed away.3500/53 of the 133388-01
Set the alert clock WDT(watchdog)--if the execution time of the program per cycle exceeds the time specified by WDT,it indicates that the program has entered the dead cycle,and immediately alarm.
Strengthen the inspection and verification of the program-once the program is wrong,immediately alarm,and stop the execution.
Battery BACKUP for program and dynamic data-After a power outage,the status and information will not be lost by using the backup battery.
PLC factory test project,there is an anti-interference test.It is required to withstand interference pulses with amplitude of 1000V,rise time of 1nS and pulse width of 1μS.In general,the average time between failures can reach hundreds of thousands to millions of hours;The system can also reach 40,000 to 50,000 hours or even longer.
硬件措施：3500/53 133388-01
主要模块均采用大规模或超大规模集成电路，大量开关动作由无触点的电子存储器完成，I/O系统设计有完善的通道保护和信号调理电路。
屏蔽——对电源变压器、CPU、编程器等主要部件，采用导电、导磁良好的材料进行屏蔽，以防外界干扰。
滤波——对供电系统及输入线路采用多种形式的滤波，如LC或π型滤波网络，以消除或抑制高频干扰，也削弱了各种模块之间的相互影响。
电源调整与保护——对微处理器这个核心部件所需的+5V电源，采用多级滤波，并用集成电压调整器进行调整，以适应交流电网的波动和过电压、欠电压的影响。
隔离——在微处理器与I/O电路之间，采用光电隔离措施，有效地隔离I/O接口与CPU之间电的联系，减少故障和误动作；各I/O口之间亦彼此隔离。
采用模块式结构——这种结构有助于在故障情况下短时修复。一旦查出某一模块出现故障，能迅速更换，使系统恢复正常工作；同时也有助于加快查找故障原因。
·软件措施：3500/53 133388-01
有极强的自检及保护功能。
故障检测——软件定期地检测外界环境，如掉电、欠电压、锂电池电压过低及强干扰信号等。以便及时进行处理。
信息保护与恢复——当偶发性故障条件出现时，不破坏PLC内部的信息。一旦故障条件消失，就可恢复正常，继续原来的程序工作。所以，PLC在检测到故障条件时，立即把现状态存入存储器，软件配合对存储器进行封闭，禁止对存储器的任何操作，以防存储信息被冲掉。3500/53 133388-01
设置警戒时钟WDT（看门狗）——如果程序每循环执行时间超过了WDT规定的时间，预示了程序进入死循环，立即报警。
加强对程序的检查和校验——一旦程序有错，立即报警，并停止执行。
对程序及动态数据进行电池后备——停电后，利用后备电池供电，有关状态及信息就不会丢失。
PLC的出厂试验项目中，有一项就是抗干扰试验。它要求能承受幅值为1000V，上升时间1nS，脉冲宽度为1μS的干扰脉冲。一般，平均故障间隔时间可达几十万～上千万小时；制成系统亦可达4～5万小时甚至更长时间。
