對于編碼器來說，“分辨率”除了與刻線數(shù)有關外，還會因電氣信號方面的影響而改變，它是可調的，可控的，它可以隨著對信號的細分而改變，細分倍數(shù)越高，分辨率越小，但是細分倍數(shù)越高，引入加大的誤差就越大。而精度，更多的偏向于機械方面，一個產(chǎn)品生產(chǎn)出來后，他的精度基本已經(jīng)固定（有些高精度的產(chǎn)品可以對信號進行補償?shù)葋硖岣呔龋?，這個數(shù)值是通過檢測出來的，它與產(chǎn)品的做工，材料等綜合性能息息相關，我們難以通過計算來得出一個具體的數(shù)值作為精度的依據(jù)，大多只能在使用的過程當中判斷出精度的好壞來。 例如，對于13bit的，其碼盤上的絕對位置數(shù)為：8192，則：計算出的分辨率為158角秒，也就是說，在讀取數(shù)值的時候，要求數(shù)值間的跳動是158角秒，如果要讀取的第一個數(shù)值是0，則第二個讀取的數(shù)值要大于158，若要小于158，則我們需要選取更小的分辨率。當要讀取158這個數(shù)值的時候，由于誤差的存在，并不可能得到絕對的158秒，編碼器所讀取出來的158秒與絕對真實158秒之間的誤差，就取決于精度了。所以說，精度，是在分辨率的基礎上來談的。 而并非越細分得到小的分辨率就越好，因為細分會引入誤差和擴大誤差，過度的細分將無法保證精度！需要多少倍的細分，能做到多少倍的細分，前提必須是在保證精度的基礎上進行的，因為精度在使用前的不可見性而高倍細分是不負責任的。碼盤質量越高，刻線越好，信號質量信號越好，細分后產(chǎn)生的誤差就越小，這受到一臺編碼器綜合性能的影響，這也就是為什么會在相同的參數(shù)下，會有不同品牌，不同價位編碼器的一個原因。

如何使用預定義數(shù)據(jù)類型UDT1“FILE_DB_HEADER”進行S7-300和S7-400的FTP通信？

S7-300和S7-400可以通過Advanced/IT以太網(wǎng)CP卡使用多種FTP功能?？梢栽谝韵氯N模式中選擇：

• FTP客戶端：
  通過“FTP_CMD”指令塊觸發(fā)FTP指令。CP卡訪問遠程FTP服務器。
• 使用CPU數(shù)據(jù)的FTP服務器：
  遠程FTP客戶端訪問CP，CP將文件訪問轉發(fā)到CPU。例如，一個文件被存儲在CP中，之后CP會將文件內容保存在CPU中的相應數(shù)據(jù)塊中。
• 使用CP文件系統(tǒng)的FTP服務器：
  遠程FTP客戶端訪問CP。文件只被存儲在CP的文件系統(tǒng)中而不會轉發(fā)到CPU。

除了最后一個模式之外的所有模式必須使用CPU中的一個指定結構的數(shù)據(jù)塊。在每個文件DB的開始必須使用預定義的數(shù)據(jù)類型UDT1 “FILE_DB_HEADER”，該數(shù)據(jù)類型可以從SIMATIC_NET_CP指令庫中找到。

Chen Piao was 16 years old from the river to the wind in the wind, in the more developed early, strong, brave and decisive character. Small fire wheel down the river, Chen float side boat side, and came to the cab Jenkins chat. They looked at the river, sometimes a few finless porpoise playing in the water, not well-known white birds around the small fire wheel upside down, the distant waves shining bright light shining in the sun, the two sides of Castle Peak and small fire round to go, this is really like a dream, everything is so natural, so harmony. Jenkins enjoyed the beautiful natural scenery, mesmerizing: "ah, this place is beautiful." Chen Piao reminded him: "you are not to experience the evil beach to stimulate feelings of it, we have to walk a few minutes later!" "Then I can't miss the golden opportunity or go to the deck to enjoy this wonderful experience."!" Said Jenkins, walking from the cab to the deck of the small fire wheel, and looking ahead. Pibozhanlang small fire wheel rapidly toward the beach for evil, Captain Chen Piao two big eyes staring at a bayonet bayonet practice of warriors, fast to the devil beach, he put the bow in front of the big black lagoon, fast marching. Standing on the deck of the Jenkins suddenly found the little steamer to the field away, he was scared, shouted: "my God, are you crazy? We're going to hit the reef......" Chen drift unmoved, a small fire wheel is still rapid towards the field for the small fire wheel to hit a big moment field, desperate Jenkins decided to throw the helve after the hatchet, he took a deep breath, suddenly from the wheel of fire on the deck of the jump to the big black lagoon, at the last moment, a small fire wheel bow swing smoothly passed large black lagoon. Originally, Chen Piaogang only b is intentional, which he had sailed a beach evil trick, every evil Big Black Lagoon Beach, he always dare to ship in front of a large open field in the field, from the big stone two feet away left the bow, the ship with the waves rushed to the big black on the reef and back to the boat, so that the ship hit a reef will not only through the place near the great black lagoon. Chen drift and use this b too large field hundreds of times, no one missed. Chen Piao looked at Jenkins on the rocks and was stunned: "Jenkins!"......" In the field of Jenkins also desperaby shouted: "Mr. Chen, please help me......" The small fire wheeled relentlessly down the stream, where no ship was coming. For five days, passing ships will see a blond blue eyed foreigner standing in the field on the waving to them for help, but no one can save him. Five days later, Jenkins, standing on the rocks, was gone. Because of the death agreement, Chen Piao finally failed to get into court. The rain in the morning, Chen Piao in a grave soil put offerings, murmured: "brother, brother Jenkins died, give you revenge!" Originally, Jenkins is nominally a life-saving doctor, is actually a guy with a commit all sorts, diplomatic immunity, not only the bully, also open to Chongqing to sell opium. Some treat patients in his hospital, he secretly took western medicine to give them doping opium drugs, cure disease, but also addicted, then go, had to go to Jenkins there to buy expensive opium, lots of shining white silver flowed into Jenkins's pocket. Caughtsmokeaddiction people. Is very poor, often broken up, but because Jenkins is a foreigner, and with local authorities, local officials will wink. Chen Piao's brother once injured by accident, came to Jenkins's hospital treatment, but also infected with drug addiction, and eventually sold out all the property for the drug, resulting in his wife ran away from home, took away only two years old son. Chen Piao's younger brother so downhearted, Dutch act to death, such as Chen Piao Jenkins and the younger brother was destroyed in a few families. Since then, Chen Piao hated Jenkins this scourge of our fellow citizens who face the beast, vowed to let him die without the burial ground. Chen heard Jenkins drift love adventure, and dare to cross the beach looking for evil people, he deliberaby in the air freezing cold, Jenkins went to the hospital, and finally makes Jenkins on the hook, in addition to harm people.Cherry wake up, found himself lying in the hospital infusion, one side of the boyfriend beam tone, and got up and said to go out to buy her food. Cherry just remembered that she was in a traffic accident on the way. Looking at the back of her boyfriend, she was very happy, and slept in the daze. When the cherry woke up again, but not her boyfriend saw her rival, but she had the good sisters Su Qin, she could not help but embarrassed: had to take beam Zhi, myself but so many scheming! At this point, Su Qin handed a new twist, gloating: "cherry, the car accident, you are proud of the legs, I'm afraid it will leave sequelae.". We have many years of friendship, so we bought a pair of crutches for you......" The cherry had changed her face, and felt the lower limbs. She looked to the door and hoped her boyfriend would come back soon. Su Qin sneer at: "you don't see, Liang Zhi in order to take care of you, make oneself too tired, faint in the road, and now in another hospital lie down?". I'm going to take care of him." Finishing cold out of the ward. Cherry quickly borrow the nurse's cell phone, call Liang Zhi number, the other party has been shut down. Cherry is very worried about Liang Zhihe Su Qin zhongxiujiuhao, vowed to retake Leung chi. She actively cooperated with the treatment, and after a few months, she was able to walk normally. On the day of discharge, cherry came to Sue's dormitory with a pair of crutches. "Thank you for your crutches," said sarcastically. "I'm sorry I didn't use it."." Seeing cherry's legs intact, Sue smiled and took out his cell phone. Cherry see beam sent to Su Qin SMS, just understand everything. Originally, the beam Zhi decides that the cherry can become a cripple, after she wakes up, abandoned her, and turn to pursue Su qin. Su Jean received beam confession message, scolded him for a while, but selfish Liang Zhi or leave the cherry. Su Qin worry cherry cannot stand double attack, intentionally sent crutches, and lied to take care of beam annals, to stimulate the cherry fight, let her live well. Cherry tears, hugged Su Qin: many years ago, they had the good sisters agreed to squeeze in a bed, if two people have a helpless, another is the other side of the crutch. Su Qin, the "rival in love", honored his promise in a special way......The old knife is not a knife, but early old yamen for a line of business, after all, is holding a broken knife head. The old knife who are usually very idle, the prisoner was busy execution in autumn days, the usual salaries are high, can cut the head of both business and bad luck, a blood stained light, so few people willing to do this line. The old town old knife, Lee three is one of the best known, he is not only a knife, and a knife. Lee three parents died early, and his wife and children, and only Brother Lee Sishui. That year, Li Sishui was accused of murder was sentenced to life, cut lijue, yamen another old knife just leave this job, behoove to send to Lee three. At that time, the old city was a sensation, and people wanted to see that Li Shan, who had cut his head and eyes all day, could kill his own brother. On the day of the execution b, huge crowds of people. In the three minute, for the gun rang, I saw Lee three shoulder guillotine knife, embrace old jars, with vigorous strides to the guillotine. He approached Li Sishui, slapping the jars, poured two bowls of wine, holding a bowl to his brother: "four water, you have made the law, Providence will not forgive. Today, you drink a bowl of wine from my brother. I'll take you on the road." Li Sishui finished the wine in tears and choked and said, "brother, wait a minute and give your brother a good time."." Cut open!" The execution officer gave the order, Li Sanshan and kill another bowl of wine, while guillotine knife, with a shout, blood splatter, Lee Sishui beheaded. Onlookers crowd first, and then burst into a burst of applause. Li Sanshan, however, was as heavy as water, without a drop of tear, and turned and strode away. Since then, people have secretly said that the Li three knife ruthless, more ruthless people. Li three exercises a guillotine knife, beheaded countless, old alone, lives alone in a lonely house. A year after the autumn evening, Li Sanshan is home to drink, heard someone knock gently. Open a look, outside the door stood a more than 40 year old woman, still carrying two boxes in hand. The woman opened the door to see the road: "my name is Yun Niang, but you yamen Li Lao Dao?"Li San asked suspiciously, "I'm Li Sanshan. What have you got?"" Yun Niang don't talk, just smile, open the door on the left side of the box, which is "Shuang Zhai building" several exquisite dishes, a pot of good fen; open on the right side of the box, there is a box full of horseshoe silver. Yun Niang wine dishes, and put the money to Lee then next to the front three, Lee three sit face blush. Lee Hill sat, face falling away from him "mother:" you have what I said, "if equivocate please leave my tricks." "Mother stay, then gave a smile:" said Lee knife cold cold heart, beheading does not bb, even kill brother don't shed a tear, did not think so." See Li three face color, Yun Niang sighed suddenly thump to his knees, "please be old." "The mother said, her husband died early, leaving only a posthumous child named tianbao. Half a year ago, Tianbao and several local ruffians fight, accidentally killed a, was sentenced to the guillotine. "In order to keep the mother son life, build on, bought the execution of up and down, now Li Sanshan, as long as the execution on the same day, Lee three mercy beheaded when pretending to be missed, cut the rope tied to Tianbao, Tianbao will took the opportunity to escape death. Lee three bate, a sneer at: "you take me as what Li Sanshan? If I am greedy shameless, take this to the court with a guillotine knife for me?" He picked up the gleaming guillotine knife, coldly looking at Yun niang. "Mother looked at the knife, suddenly asked:" do you not in this life to do anything creepy? The confiscation of a paper money bribe?" Who but Li Sanshan laughed a shot back: "you're right, I do a lifetime of Li three old knife, cut not corrupt officials, is the bully. Others have bought me, but I swear to the blue sky, I confiscated a penny, yes, killed a person." Look at Lee "Sanshan generously appearance, Yun Niang do not know this thing. Suddenly, she curiously asked: "are you that you never mercy?" "Sure."!" Li Sanshan says. "The mother asked again:" if you want to kill people is your nephew?" Li Shan frightened: "what did you say?"" Yun Niang took a yellowed letter from the bosom, threw him: "when you can kill your brother, I'd like to know now, you can kill your nephew?" Finish off. Li Sanshan read the letter, pale, and suddenly squatted on the ground. The letter he knew was written by his brother Li Sishui. Originally, when Lee Sishui was secretly in love with Yun Niang, the Niang "is a widow, he didn't dare to bl my brother that Li Sishui later field was killed, soon," mother gave birth to a posthumous child, is to be beheaded Tianbao Lee three. The letter said, for Li in Sanshan brothers, after his death, must take good care of mother and child ". Li Shan hands shake, the letter fell to the ground.On the day of the execution, Lee three heavy heart came to the place of execution, Tianbao were brought up, Lee three looking more and more like brother feel Tianbao four water. A little time in the past, looked at the deception gun will ring, pulling the painful heart Li mountain top, he had killed his brother, suffering a life, is now going to kill nephew? He was sweating profusely, and never shook hands with his powerful hands. Are hesitant, deception gun rang, he suddenly looked up, suddenly saw the broken sword in his hand. This knife is when his master sun came to his old knife, sun dry old knife fifty old knife, Li Sanshan remember, Lin master knife to him, said: "the world has a knife, long and short, fast blunt, there are evil, only the guillotine knife, endowed with righteousness, it is illegal to kill people, is the world of public support to. Law enforcement people do not have the heart, or the guillotine knife, broken but not cut off the head, or the world fair!" Li three mountains think of master's words, suddenly a sudden drink, lift the guillotine knife, go to the sky treasure to swing. In a moment he had thought, such as kill Tianbao, he commits suicide, the dead brother to sin. The sky was streaming with blood! Li Mongolia saw Tianbao Sanshan has been beheaded, but again Rouyan, but found Tianbao head intact, the body of the rope is opened. I saw him Tianbao smiled and jumped to death, swiftly ran. Li three mountain urgent, he shouted, carrying a broken knife on the chase to tianbao. Tianbao young quick legs, Li three hills after a long time, only to see the back of tianbao. He could not help shouting: "give me stop!"!" Tianbao turns back, Hei hei laughed and said: "I am not a fool, I stop, not waiting for you to cut it?"" Li Sanshan red eyes say: "Sharenchangming Qianzhaihuanqian! If you break the laws of the land, I can't help killing you." Tianbao eyes strange, running side said: "my father is your younger brother, I am your nephew!"." Li Shan gasped, still walking: "when I cut you, I'll commit suicide."." Tianbao: "to cut me, you have to chase."." Then, to speed up the pace. So, two people race each other, from the dark to dawn, tramp over mountains and through ravines, from dawn to dusk. Don't know how long before seeing a touch the sky in front of the city, the city gate stands a woman, a woman ran around in Tianbao, panting behind her, said: "mother, save me!"
