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(xiàn)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(gè)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(qū)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(qū)域中的設(shè)備。
SST-PFB3-VME-2-E控制卡件5、該區(qū)域未解碼。如果訪問(wèn)這些位置，并且本地總線定時(shí)器啟用，循環(huán)超時(shí)，并由TEA信號(hào)終止。1.有關(guān)寄存器位的完整描述，請(qǐng)參閱單板計(jì)算機(jī)程序員參考指南或數(shù)據(jù)表炸薯?xiàng)l
2.應(yīng)使用字節(jié)讀取來(lái)讀取中斷向量。這些位置可以中斷未掛起時(shí)不響應(yīng)。如果本地總線計(jì)時(shí)器為啟用后，訪問(wèn)超時(shí)，并由TEA信號(hào)終止。
3.VMEchip2中LCSR的寫(xiě)入必須為32位。LCSR寫(xiě)入8或16位以TEA信號(hào)終止。對(duì)GCSR的寫(xiě)入可以是8位、16位或32位。對(duì)LCSR和GCSR的讀取可以是8、16或32位。
4、該區(qū)域不返回確認(rèn)信號(hào)。如果本地總線計(jì)時(shí)器為啟用后，訪問(wèn)超時(shí)，并由TEA信號(hào)終止。
5.該區(qū)域確實(shí)返回確認(rèn)信號(hào)。
6、尺寸為近似值。
7.82596CA的端口命令必須寫(xiě)入兩個(gè)16位寫(xiě)入：上限第一個(gè)單詞和第二個(gè)較低的單詞。
8.CD2401從$FFF45200到$FFF45FFF重復(fù)出現(xiàn)。如果當(dāng)?shù)乜偩€計(jì)時(shí)器啟用，訪問(wèn)超時(shí)，并由TEA信號(hào)終止。VMEbus內(nèi)存映射本節(jié)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(wèn)本地總線VMEchip2包括一個(gè)用于VMEbus到本地總線接口。地圖解碼器允許您編程起始和結(jié)束地址以及修飾符MVME187響應(yīng)。
VMEbus短輸入/輸出內(nèi)存映射VMEchip2包括一個(gè)用于GCSR。GCSR地圖解碼器允許您編程啟動(dòng)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
