CC-PAIN01通信模塊,51410069-175中文說明
STL指令不夠直觀。調(diào)用MODBUS通訊指令庫 圖2中參數(shù)意義如下: ●模式選擇:啟動/停止MODBUS,1=啟動;0=停止; ● 從站地址:MODBUS從站地址,取值1~247; ● 波特率:可選1200,2400,4800,9600,19200,38400,57600; ● 奇偶校驗(yàn):0=無校驗(yàn);1=奇校驗(yàn);2=偶校驗(yàn); ● 延時:附加字符間延時,缺省值為0; ●最大I/Q位:參與通訊的最大I/O點(diǎn)數(shù),GForce-200的I/O映像區(qū)為128/128,缺省值為128; ●最大AI字?jǐn)?shù):參與通訊的最大AI通道數(shù),
CC-PAIN01通信模塊可為16或32; ●最大保持寄存器區(qū):參與通訊的V存儲區(qū)字(VW); ● 保持寄存器區(qū)起始地址:以&VBx指定(間接尋址方式); ● 初始化完成標(biāo)志:成功初始化后置1; ● 錯誤代碼:0=無錯誤。 (4) 注意的問題 調(diào)用Step7-Mciro/WIN32 V3.2 Instruction Library(指令庫)需要分配庫指令數(shù)據(jù)區(qū)(Library Memory)。庫指令數(shù)據(jù)區(qū)是相應(yīng)庫的子程序和中斷程序所要用到的變量存儲空間。如果在編程時不分配庫指令數(shù)據(jù)區(qū),編譯時會產(chǎn)生許多相同的錯誤。 由子程序參數(shù)HoldStart和MaxHold指定的保持寄存器區(qū),是在GForce-200 CPU的V數(shù)據(jù)存儲區(qū)中分配,此數(shù)據(jù)區(qū)不能和庫指令數(shù)據(jù)區(qū)有任何重疊,否則在運(yùn)行時會產(chǎn)生錯誤,不能正常通訊。注意Modbus 中的保持寄存器區(qū)按“字”尋址,即MaxHold規(guī)定的是VW而不是VB的個數(shù)。
3 Modbus RTU協(xié)議測試 包含Modbus RTU從站指令庫的項(xiàng)目編譯、下載到CPU中后,在編程計算機(jī)(PG/PC)上運(yùn)行一些Modbus測試軟件可以檢驗(yàn)GForce-200的Modbus RTU通訊是否正常,這對查找故障點(diǎn)很有用。測試軟件通過計算機(jī)串口(RS-232)和PC/PPI電纜連接CPU。卷揚(yáng)機(jī)房設(shè)備 光電編碼器1臺,用于測量卷揚(yáng)機(jī)鋼纜長度,確定罐籠所在位置;騰控T-910 PLC 1臺,用于采集光電編碼器數(shù)據(jù)并傳輸至網(wǎng)絡(luò);電氣控制柜1臺,用于安裝PLC和相關(guān)電氣采集、控制回路;24V電源模塊1個,為PLC供電和PLC外部開入、開出供電。

These sensors may be deployed locally, regionally or globally. Regardless of the size, each deployed IOT will be different in terms of what data is collected, how and why.
Challenging environment
From the physical environment, some industrial iots are easy to deploy. If you're lucky, you can deploy sensors to facilities where the climate is completely controlled. However, in many cases, where sensors and other sensitive network equipment need to be deployed, the environment is harsh, including high temperature, severe cold and poor ventilation conditions. Clean energy is also an important aspect to pay attention to. In many cases, the industrial Internet of things needs rugged Internet of things sensors and network hardware to withstand this type of physical environment challenges.
