GE IS200SRTDH2ACB RTD 接線板
IS200SRTDH2ACB信號在接入計算機前，在信號線與地間并接電容，以減少共模干擾；在信號兩極間加裝濾波器可減少差模干擾。
對干較低信噪比的模擬量信號．常因現(xiàn)場瞬時干擾而產(chǎn)生較大波動，若僅用瞬時采樣植進行控制計算會產(chǎn)生較大誤差，為此可采用數(shù)字濾波方法。IS200SRTDH2ACB現(xiàn)場模擬量信號經(jīng)A／D轉(zhuǎn)換后變成離散的數(shù)字信號，然后將形成的數(shù)據(jù)按時間序列存入PLC內(nèi)存。再利用數(shù)字濾波程序?qū)ζ溥M行處理，濾去噪聲部分獲得單純信號， 可對輸入信號用m次采樣值的平均值來代替當前值，但井不是通常的每采樣。次求一次平均值，而是每采樣一次就與最近的m－l次歷史采樣值相加，此方法反應速度快，具有很好的實時性，IS200SRTDH2ACB輸入信號經(jīng)過處理后用干信號顯示或回路調(diào)節(jié)，有效地抑制了噪聲干擾。
In IS200WNPSH1ABAcontrol system, power supply plays a very important role. Power grid interference is cascaded into the PLC control system mainly through the coupling of power supply of IS200WNPSH1ABA system (such as CPU power supply, I / O power supply, etc.), transmitter power supply and instrument power supply with direct electrical connection with IS200WNPSH1ABA system. Now, for the power supply of IS200WNPSH1ABA system, the power supply with good isoIS200WNPSH1ABA lation perbance is generally used. However, the power supply of transmitter and the power supply of instrument with direct electrical connection of IS200EGPAG1BCA system have not been paid enough attention. Due to the complexity of electromagnetic interference, it is impossible for is200hslah2ade to fundamentally eliminate the impact of interference.
Therefore, anti-interference treatment should also be carried out in software during the software design and configuration of PLC control system to further improve the reliability of the system. Some common measures: digital filtering and power frequency shaping sampling can effectively eliminate periodic interference; The reference point potential is corrected regularly and the dynamic zero point is adopted. Is200hslah2ade can effectively prevent potential drift; IS200WNPSH1ABAAdopt inbation redundancy technology and design corresponding software flag bits; Indirect jump and software trap are adopted to improve the reliability of software structure.Before the is200srtdh2acb # signal is connected to the computer, connect the capacitance between the signal line and the ground in parallel to reduce the common mode interference; Adding a filter between the two poles of the signal can reduce the differential mode interference.
For analog signals with low signal-to-noise ratio, large fluctuations are often caused by on-site instantaneous interference. If only instantaneous sampling is used for control calculation, large errors will be generated. Therefore, digital filtering b can be used. Is200srtdh2acb # field analog signal is converted into discrete digital signal after a / D conversion, and then the bed data is stored in PLC memory according to time series.
