S7-PLCSIMV5.4
西门子仿真编程软件S7-PLCSIM V5.4,用于S7-300/400系列PLC程序的仿真(S7-PLCSIM V5.4 offers the following new features with this release:
DP, Industrial Ethernet and PC Internal connection types supported in addition to MPI
Formerly, S7-PLCSIM used a default connection of MPI, address 2. With S7-PLCSIM V5.4, you can browse STEP 7 projects and select a networked node for establishing a simulation connection. S7-PLCSIM simulates the CPU of the selected node, all nodes that belong to that CPU, and the subnet of the selected node.
Increased number of blocks supported for simulation
S7-PLCSIM supports a set of OBs, SFBs, and SFCs as described in the electronic manual and online help. Of these, some are NOPs that is, they do not perform any operation. With S7-PLCSIM V5.4, the number of blocks that are not NOPs has increased.)

数据库术语
数据库编程的工作方式
SQL
连接环境
在连接环境中,应用程序会持续连接到数据源上
优点
连接环境更易于维护
并发控制更容易
与非连接环境相比,数据更容易刷新
缺点
必须维持稳定的网络连接
有限的可扩展性
非连接环境
非连接环境是指可以在本地对数据进行单独修改,然后再把修改更新到数据库
优点
与数据源保持连接的时间短,而且并发访问的连接数少,从而能为更多用户提供服务
非连接环境大大增加了连接的可用性,从而改善了应用程序的可扩展性和性能
缺点
数据不总是最新的
可能发生更改冲突,这是个必须解决的问题 ()
