SST-PFB3-VME-2-E控制卡件，SST使用教程
1.板載EPROM在本地總線之后出現在$00000000-003FFFFF重置。EPROM顯示為0，直到在
VMEchip2。ROM0位位于地址$FFF40030位20。這個在啟用DRAM之前，必須在0禁用EPROM。VMEchip2和DRAM映射解碼器被本地總線重置禁用。
2、該區域可由用戶編程。建議使用如表所示。DRAM解碼器在MEMC040或MCECC芯片中編程，并且本地到VMEbus解碼器在VMEchip2中編程。
3、尺寸為近似值。
4.緩存抑制取決于映射區域中的設備。
SST-PFB3-VME-2-E控制卡件5、該區域未解碼。如果訪問這些位置，并且本地總線定時器啟用，循環超時，并由TEA信號終止。1.有關寄存器位的完整描述，請參閱單板計算機程序員參考指南或數據表炸薯條
2.應使用字節讀取來讀取中斷向量。這些位置可以中斷未掛起時不響應。如果本地總線計時器為啟用后，訪問超時，并由TEA信號終止。
3.VMEchip2中LCSR的寫入必須為32位。LCSR寫入8或16位以TEA信號終止。對GCSR的寫入可以是8位、16位或32位。對LCSR和GCSR的讀取可以是8、16或32位。
4、該區域不返回確認信號。如果本地總線計時器為啟用后，訪問超時，并由TEA信號終止。
5.該區域確實返回確認信號。
6、尺寸為近似值。
7.82596CA的端口命令必須寫入兩個16位寫入：上限第一個單詞和第二個較低的單詞。
8.CD2401從$FFF45200到$FFF45FFF重復出現。如果當地總線計時器啟用，訪問超時，并由TEA信號終止。VMEbus內存映射本節描述了由查看的本地資源映射VMEbus masters。從屬、主和GCSR地址解碼器由ENV命令提供。參考附錄A。
VMEbus訪問本地總線VMEchip2包括一個用于VMEbus到本地總線接口。地圖解碼器允許您編程起始和結束地址以及修飾符MVME187響應。
VMEbus短輸入/輸出內存映射VMEchip2包括一個用于GCSR。GCSR地圖解碼器允許您編程啟動VMEbus短輸入/輸出空間中GCSR的地址
and the corresponding material kilogram will be automatically converted by PLC and imported into the system for application. The curve rate is obtained according to the weight of the test weight and the curve characteristics of the module (see the instruction description of the module curve rate for details).
PLC: the program adopts wplsoft2 35 ladder diagram software. It includes four main parts: system setting, analog quantity acquisition, automatic operation and manual operation. Scan the ladder diagram during operation, automatically jump and switch according to external instructions, and execute continuously.
Process control:
The console is equipped with manual / automatic transfer switch, emergency stop button, on-board quantity input button, automatic operation start button, system reset button, etc. For manual operation, each mechanism can be controlled independently.
On board quantity input button: each time you press it, the on-board quantity counter will automatically increase by one, and long press it to clear the data. You can also input the value directly through the touch screen. System reset button: clear the non power failure storage area register to return the system to standby state.
According to the construction requirements, input the corresponding data command through the man-machine interface, press the automatic operation start button, and the system will operate automatically and continuously. The operation process is divided into three stages: batching, feeding, mixing and concrete unloading.
1. Batching: the automatic operation start contact triggers the batching and metering of 4 aggregates, cement, chemicals and water. After the aggregate batching is completed, the system detects the hopper position. When the hopper is at the lower limit, the weighing belt is fed, and the weighing belt timer is started. When the time reaches, it will stop automatically. After the feeding of the weighing belt is completed, the system detects and waits: the host starts, the batching of cement, water and reagent is completed, and the hopper lifting is triggered when the mixing of the previous tank of concrete is completed and the concrete unloading door is closed. In this way, continuous material input into the host is effectively avoided. When the hopper is lifted, the PLC triggers the sampling of the historical data buffer, and records and saves the batching measurement value in columns according to the time and date.
2. Feeding: when the hopper is lifted in place, it will stop automatically. Put the aggregate into the main engine. The corresponding timer starts, and when the
