FM350-2高速計(jì)數(shù)器程序說(shuō)明

1、FM350-2 高速計(jì)數(shù)器實(shí)例A:在FM350-2 入門指南和FM350-2 使用入門中，就列出了西門子的樣例程序和庫(kù)文件的打開(kāi)辦法。實(shí)際應(yīng)用中，找到相應(yīng)的任務(wù)號(hào)傳送到 DB 塊的寄存器中。任務(wù)號(hào)要看FM350-2 安裝和參數(shù)配置。Q:看了這說(shuō)明書還是不太理解，硬件地址是 480-495 不知如何寫數(shù)，這數(shù)的意思還是不太理解。A:如果在硬件設(shè)置里指定了該模塊對(duì)應(yīng)的 DB 塊【Moduleadressfordatablock,那么模塊的邏輯地址和通道地址無(wú)需在程序中再次編程設(shè)定。然后調(diào)用 FC2,同時(shí)指定前期生成的 DB 塊號(hào)；然后調(diào)用 FC4,并通過(guò)對(duì) DBB2 設(shè)置工作號(hào) 100 或 101

2、 來(lái)對(duì) 03 或 47 號(hào)通道進(jìn)行讀值；07 通道對(duì)應(yīng)的編碼器值，為DBD148、DBD156-DBD204。Q:DBB2 設(shè)置工作號(hào) 100 或 101 什么意思， 找不至 U 啊， DBD148、 DBD156DBD204又不智道道在那，我選了 db1 數(shù)據(jù)塊A:簡(jiǎn)單的編程：etvocrk2:Title:CNT2_CTREMENOINONetwork3:Title:Ccimnent:DELD0X23.飛100.0*01/1()-DELDBX23.I1Network4:Title:Comment:MOVEENENOINOUT-DB1.DBB2Network5:Title:Cojiment:*

4、#16#1 同樣是指定 DB 塊號(hào)。此時(shí)在程序中調(diào)用 DB1.DBD148,即可獲得計(jì)數(shù)器 0 的計(jì)數(shù)值；調(diào)用DB1.DBD156,可獲得計(jì)數(shù)器 1 的計(jì)數(shù)值。工作號(hào)的含義：其實(shí)對(duì)簡(jiǎn)單的使用來(lái)說(shuō)用不到幾個(gè)的。就用上邊提到的就可以讀出計(jì)數(shù)器值了。ReadJobYoutriggeranev；readjobbyenteringareadjobinJOB_RD.NOThefollowingreadjobsarepermitted:JOB_RD.NO(DBB2)EntryinUDT1AddressinCounterDBMeaning0NoneNoneNoreadiobilastreadiobcoITpl
