Hello Jenda, thank you for your interest.

I need to communicate with an industrial automation program called Intouch from Wonderware. This application is widely used in industrial applications to create operator interfaces that communicate with Programmable Logic Controllers (PLC). Intouch supports two types of inter-process communictions DDE and SuitLink. SuitLink is the equivalent of OPC (OLE for Process Control) but is not compatible. I've searched arround to see if someone had developped a Perl SuitLink extension, but unfortunately the answer is no. If I had a little more time and budget on my project, I would go to the extent of creating my own and share it with others but here again my ressources are limited. So to me, for as long as DDE is supported by Intouch, I guess it's a viable solution.

Again, DDE work extremely well, but I don't understand why it fails within a service.

Thank you again.

Dan
