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
主要模塊均采用大規模或超大規模集成電路，大量開關動作由無觸點的電子存儲器完成，I/O系統設計有完善的通道保護和信號調理電路。
屏蔽——對電源變壓器、CPU、編程器等主要部件，采用導電、導磁良好的材料進行屏蔽，以防外界干擾。
濾波——對供電系統及輸入線路采用多種形式的濾波，如LC或π型濾波網絡，以消除或抑制高頻干擾，也削弱了各種模塊之間的相互影響。
電源調整與保護——對微處理器這個核心部件所需的+5V電源，采用多級濾波，并用集成電壓調整器進行調整，以適應交流電網的波動和過電壓、欠電壓的影響。
隔離——在微處理器與I/O電路之間，采用光電隔離措施，有效地隔離I/O接口與CPU之間電的聯系，減少故障和誤動作；各I/O口之間亦彼此隔離。
采用模塊式結構——這種結構有助于在故障情況下短時修復。一旦查出某一模塊出現故障，能迅速更換，使系統恢復正常工作；同時也有助于加快查找故障原因。
·軟件措施：3500/53 133388-01
有極強的自檢及保護功能。
故障檢測——軟件定期地檢測外界環境，如掉電、欠電壓、鋰電池電壓過低及強干擾信號等。以便及時進行處理。
信息保護與恢復——當偶發性故障條件出現時，不破壞PLC內部的信息。一旦故障條件消失，就可恢復正常，繼續原來的程序工作。所以，PLC在檢測到故障條件時，立即把現狀態存入存儲器，軟件配合對存儲器進行封閉，禁止對存儲器的任何操作，以防存儲信息被沖掉。3500/53 133388-01
設置警戒時鐘WDT（看門狗）——如果程序每循環執行時間超過了WDT規定的時間，預示了程序進入死循環，立即報警。
加強對程序的檢查和校驗——一旦程序有錯，立即報警，并停止執行。
對程序及動態數據進行電池后備——停電后，利用后備電池供電，有關狀態及信息就不會丟失。
PLC的出廠試驗項目中，有一項就是抗干擾試驗。它要求能承受幅值為1000V，上升時間1nS，脈沖寬度為1μS的干擾脈沖。一般，平均故障間隔時間可達幾十萬～上千萬小時；制成系統亦可達4～5萬小時甚至更長時間。
