Hi, i have dll which controls the instruments. I have to communicate with multiple nr. of devices(5-8) in Parallel using LAN interface.I have designed my process like below: Framework (for inilialization, UI, and loading subpanel)-->AsynCallreentrant.vi ( call the nr of instances (clones) using Asyn node) --> Subvi (reentrant execution Vi Property and dll call). If i call the same dll using for example subvi:1(clone), subvi:2(clone),..and so on, then only one device works properly and other returns the error. How to solve this problem?? How to make copies of same dll (non reentrant dll) for the reentrant calling? Is there any dynamic ways that clone 1 calls the dll and clone 2 calls making copy of it (dll-copy)?

It works with vi server too. Every control of executable can be accessed just setting the computer name (ip or localhost) and distinct port addreses. 🙂
