2) When implementing a supervisory control device on a computer, the input / output processing of a computer process occupies a large part of data file access, shared memory access, and communication processing between processes. Since the realization method differs between computers and computers over a network, it is very difficult to make the processing compatible with both. Also, since the file / shared memory to be input / output, the physical name of the process to communicate with, and the network location are usually defined inside the computer process, it is impossible to change them freely.
