DRAM编程注意事项
❏ DRAM映射解码器可以编程为适应不同的基址和大小夹层板。
❏ 车载DRAM由本地总线重置禁用，必须在可以访问DRAM之前编程。
❏ 大多数DRAM设备需要一定数量的访问周期DRAM完全运行之前。
–通常情况下，车载刷新可以满足此要求电路和正常DRAM安装。然而软件应确保至少10次初始化对每个RAM组执行循环。参见单板计算机中的MEMC040或MCECC

The start button is used to start the washing machine, and the stop button is used to manually stop water inflow, drainage, dehydration and alarm. The drainage button is used to realize manual drainage.
1. Control requirements
The of the automatic washing machine can be represented by the flow chart shown in the figure below.
After pressing the start button, the washing machine starts to fill with water. When the water is full (i.e. the water level reaches the high water level, and the high water level switch changes from off to on), the PLC stops feeding water and starts the forward rotation of washing. The forward rotation is suspended after washing for 15s, and the reverse rotation of washing is started after suspending for 3S. Pause after backwashing for 15s. After 3S suspension, if the washing and backwashing are not full for 3 times, return to the action starting from washing; If the front and back washing are full for 3 times, start drainage. When the water level signal drops to the low water level (the low water level switch changes from on to off), start dehydration and continue drainage. Dehydration for 10s is to complete a large cycle process from water inlet to dehydration. If 3 large cycles are not completed, the washing completion alarm will be given. After 10s of alarm, the whole process will be ended and the machine will stop automatically.
In addition, it is also required to press the drainage button to realize manual drainage; Press the stop button to manually stop water inlet, drainage, dehydration and alarm. Labeller is a device that pastes paper or metal foil labels on specified packaging containers with adhesive. Labeling machine is an indispensable part of modern packaging. At present, the types of labeling machines in China are gradually increasing, and the technical level has also been greatly improved.
