如果系統設計不是你自己做的，那么在出發前，就要與系統的設計人員進行充分的溝通，
對于不清楚和不明白的地方，一定要弄清楚，確保自己清晰地理解了要完成的工作目標，
和設計者的意圖。不要輕易否定設計者的方案，也不要輕易地說別人那里設計得不行。
但是，因為你是從事現場的工程師，因此，也不必過于迷信設計者。你可以提
出自己的建議。比如，PLC的機架和CPU模塊和I/O模塊的搭配原則，可能有時候，*****不
知道你所用的 PLC的機架有4槽、6槽和8槽，甚至12槽的，因此，也許全部都選了8槽的，
而導致了幾個槽的空缺，你可以建議它修改為4槽或6槽的。
方案設計中，容易出問題的地方是通訊，現場調試麻煩的地方也是通訊，
所以對于通訊的部分，你必須清晰了解系統的框架結構，并且對需要進行通訊的東西在出
發前就要全部進行一遍調試，而且要確認其中的所有需要通訊的模塊是可以通訊的。比如，
操作臺電腦、觸摸屏、PLC、變頻器、其它的PLC、一些智能儀表和儀器，如果這些東西需要
通訊的話，你必須要確認它們相互之間是可以通訊的，如果你不確認的話，就要與廠家聯
絡，并親自再試一次。如果PLC的節點數較多，要考慮距離和廠家CPU的限制。
