看来很多文档,可是我没有用过java,从文档可以看到通过PC用S7beans
Advantages
With Java applications, you have a far greater range of options than with Java
applets because the applications are not subject to the strict security guidelines of
the sandbox. You can, for example, implement access to a different SIMATIC
stations at the same time and collect the data of these stations centrally on a PC;
alternatively variable values of an S7-CPU can be stored on local PC for further
processing.
可以访问PLC,是否能够PLC用java访问PC呢?
