我想把IM151-8作为智能设备,这两个选项啥意思?下面我附上帮助文档。
Here, you make the settings for creating the transfer areas. There are two types of transfer area:
· Application transfer areas are an interface to the user program of the CPU. Inputs are processed in the user program and outputs are the result of the processing in the user program.
