I have parallel model with 8 sockets. Each of sockets has VI called "Open_Excel_File.VI" that openes excel file and read/write data to it. If Any of 8 testsockets open VI at the same time, i get error that excel file is not available.
How can I disable the same open/close of excel file in all 8 test sockets, so if one of sockets opens excel, others has to wait that excel is again availabe and then open it?
