I am dealing with similar problem with the comunication of my 5850 MFC's and the PC. Could you give me the link to download the smart dde protocol. Thanks a lot. (firstname.lastname@example.org)
I am having some SmartDDE lockup issues for the brooks 0154 as well, what was the resolution on this issue. I query the smart DDE as well as set the flow of the MFC quite often for a process control. Now that I have the unit in my process control I am having the SmartDDE crash on me. The Smart DDE is even worse sincy it can not be restarted since it closes the application but leaves the processes open. Since this is a seperate application there is no easy communication with the software. What was the cause of the smartDDE lockups? Am I communicating with it too fast (add a wait after each DDE call) the crash recovery will be a bit of a pain to implement since I will have to use an elapsed time to detect if the communication has dropped then kill the processes that the DumbDDE leaves opened, then restart the SmartDDE and continue. How did others deal with this in the past. I am using LV7.1 and XP.
Look for an update of SmartDDE.
It may not be able to navigate Brooks software support but the lock-up issue was noted by my customer and it improved after the SmartDDE update.
