Question

I want to use shared memory between two applications. In this case between a c++ main-application and PLCSIM, a virtual programmable logic controller. Anyway I did not know if PLCSIM is prepared for shared memory usage. Is it possible to force PLCSIM to make it memory storage available for other processes like shown in the MSDN-example related to a main-main-interprocess-communication example: http://msdn.microsoft.com/en-us/library/windows/desktop/aa366551(v=vs.85).aspx

Was it helpful?

Solution

Im not sure what your end goal is but could you look at using NettoPLCSim. It makes use of a "COM-Interface of PLCSim to read/write the data out of it". You could use source code to make an application to store data to where you require to share with your C++ code http://nettoplcsim.sourceforge.net/
