QJ71C24 R2與E540變頻器進(jìn)行232通信，QJ發(fā)送后變頻器無反應(yīng)，在電腦上用串口調(diào)試工具發(fā)送同樣的數(shù)據(jù)，變頻器動作正常。將QJ的端口連接至電腦端口后用串口調(diào)試工具對其發(fā)送內(nèi)容進(jìn)行檢測后發(fā)現(xiàn)并無錯誤，只是獲得的數(shù)據(jù)并不是一起接收到得。先將串口調(diào)試工具獲得的內(nèi)容粘貼如下：

注：以上是串口調(diào)試工具獲得QJ發(fā)送的數(shù)據(jù)記錄，這個是變頻停止指令（用串口調(diào)試工具讓變頻器先運轉(zhuǎn)起來后再用此指令），即使是變頻器運行指令，變頻器也無反應(yīng)。為什么接收來的數(shù)據(jù)時這個樣子呢？？而不是一個長度為12的數(shù)據(jù)呢？？

注：以上是有串口調(diào)試工具向E540發(fā)送同樣的數(shù)據(jù) E540動作正常
通信設(shè)置 9600、8、 Even 、2。 QJ（SW3:05DE SW4:0006）、 E540(0號站 9600、8、even、2、CRLF結(jié)束符、通信次數(shù)為9999 )、串口調(diào)試工具均設(shè)置無誤

根據(jù)您提供的信息，變頻器不運轉(zhuǎn)是由于發(fā)送的數(shù)據(jù)沒有連續(xù)造成的，可能還是由于程序方面導(dǎo)致的，建議您最好來電咨詢，謝謝。

格式化存儲器后，寫入說明書的示例程序，發(fā)現(xiàn)數(shù)據(jù)還是不連續(xù)
后將數(shù)據(jù)線接線方式改變后，數(shù)據(jù)依舊不連續(xù)，但是有差別顯現(xiàn)
