海創IOT是基于圖形節點和流程的快速開發平臺,采用可視化編程方法,將預定義的代碼塊(稱為“節點”,Node)連接起來執行任務。連接的節點,通常是輸入節點、處理節點和輸出節點的組合,當他們連接在一起的時候,構成一個“流”(Flows),與傳統的程序開發工具相比,它更好地適應物聯場景。它可以與JavaScript和Node.js、C語言混合開發使用。基于這個平臺我們可以快速的實現西門子PLC數據的獲取 一、硬件環境 1、海創Box智能網關 2、西門子PLC 二、產品連接方式 三、產品配置 海創智能網關 請參考《海創智能網關設置》 **西門子PLC ** 配置好設備連接ip 四、項目部署調試 打開海創-IIoT。本次教程需要用到如下節點,在左側節點欄中拖拽出使用 定時器周期性觸發輸入時間戳或者相應的字符 S7西門子用于讀取S7西門子通信協議的設備數據 調試用于調試節點輸出 配置相應節點后配置界面如下: 節點配置: 定時器設置成周期性觸發,主要當觸發流程使用,具體配置如下圖 S7西門子設置如下配置,即可取到M區0.1的地址數據 調試在右側調試窗口輸出調試結果,無需配置 部署調試: 按照以上教程配置好流程后,點擊部署,部署成功后程序開始運行,就會在調試窗口輸出相應的結果,調試結果如下 [ { "id": "3c9559.b5d63aa8", "type": "iot-s7", "z": "41f61d2.fbe09e4", "name": "", "server": "f0605fb0.3a733", "columns": [ { "Key": "2號跑馬燈", "Label": "2號跑馬燈", "Address": "M0.2", "Arithmetic": "" } ], "x": 340, "y": 380, "wires": [ [ "1fa324c1.eb258b" ] ] }, { "id": "1421da2b.ec0216", "type": "inject", "z": "41f61d2.fbe09e4", "name": "", "topic": "", "payload": "", "payloadType": "date", "repeat": "", "crontab": "", "once": false, "onceDelay": 0.1, "x": 240, "y": 380, "wires": [ [ "3c9559.b5d63aa8" ] ] }, { "id": "1fa324c1.eb258b", "type": "debug", "z": "41f61d2.fbe09e4", "name": "", "active": true, "tosidebar": true, "console": false, "tostatus": false, "complete": "true", "x": 480, "y": 380, "wires": [] }, { "id": "f0605fb0.3a733", "type": "iot-s7-client", "z": "", "name": "", "communicate": "TCP", "host": "192.168.7.163", "post": "102", "baudrate": "9600", "databits": "8", "stopbits": "1", "parity": "None", "expand": {}, "connmode": "tsap", "rack": "0", "slot": "2", "localtsaphi": "10", "localtsaplo": "00", "remotetsaphi": "03", "remotetsaplo": "00", "verbose": "default" } ] |
