電腦給QJ71C24N 傳數據卡頓的問(wèn)題

請教兄弟們一個(gè)問(wèn)題
我在弄一個(gè)機器之前是好好的，不知道什么時(shí)候開(kāi)始電腦給PLC傳數據就卡頓了。
傳的數據內容很少，只有一點(diǎn)點(diǎn)。有時(shí)候正常一下子就搞定了，有時(shí)候會(huì )卡住，有時(shí)候卡住2~3分鐘才把數據傳完。不知道在做什么，反正就是要干等幾分鐘就把數據傳完了。
請問(wèn)一下，有什么好辦法檢測一下電腦卡頓的時(shí)候在干嗎？或者在等什么信息？
電腦是通過(guò)COM口接RS232到QJ71C24N 的CH1端口上。
查看了一下模塊狀況發(fā)現有報警信息，不知道跟這個(gè)問(wèn)題有沒(méi)有關(guān)系。
你們估計是啥原因呢？有什么好辦法嗎？
