      信捷PLC的性價比相對來說還算是可以，現在眾多的順控程序很多設備都在使用，我使用也有數年之久，相對來說，XC系列的PLC，到最后的版本，也基本上該有功能也基本上有了，相對來說，通過不斷的升級，也還算穩定。
    自去年開始，因業務需要，開始使用各種XD系列的PLC，但真的是很坑爹呀，那編程軟件可能是我目前用過所有的PLC中最垃圾的一個，也不知道他們公司的哪位大神，使用那樣的擴展模式，加一個擴展得后面加一個10000，真的是數著數字都煩，原來好好的，在加一個模塊后加100就可以了，這樣倒好，要給打號碼管都太長了，更別提輸這數字了，
    那軟件呢，注釋當中一大堆用不著的，也在當中，有時要找一個IO真的挺難找的，不知道用哪種PLC，里面可用的就顯示，這樣不讓人家好搞多了，還有就是那插入一行，與刪除一行，得非常小心，因為你稍不注意，乖乖，它就得轉圈圈了，死機了，沒保存，不好意思，它自動備份后寫的那部分程序，你得重來了。
    還有就是發現那軟件有一個問題，在時實性較高的東西，有時并不會從上往下的順序來的，有時得人為的增加延時等待。希望信捷的研發中心人員，能夠重視這些問題，我們是很希望國產的很好，也很愿意支持國貨，但得不影響自己工程的前提下呀。在某些方面，多學習一下國際上知名品牌的長處，對自己的產品還是很有益處的。
   我現在基本上，實時性高一點的地方還是使用國際知名品牌。一些順控制要求不高的地方使用一下信捷，我很支持國貨，但是目前為止，能用XC就盡量用XC，XD目前為止還是很不穩定。什么時候穩定時再用吧。希望信捷公司人員看到后，能知道怎么提升。讓支持你們的人不會太失望。

信捷用起來感覺真的不方便, 剛好公司最近買了幾臺設備是用于信捷PLC的, 目前要開發上位機, 感覺信捷的寄存器什么的太多了, 寫了個地址分析的函數超長啊
