Hello everybody,
I'm using MSP-GANG DLL in the production environment. I use a LabVIEW program together with the MSP-GANG DLL. And communicate via RS232 interface.
Versions:
- HW: 1.05
- SW: 1.3.8
Error description:
Sometimes (really sporadic) the main process takes longer as usual: e.g. 200s instead of 9s.
Analysis:
What I found out: When I switch the LabVIEW program at debugging mode (e.g. after 20s), the dll finishes the execution immediately.
I tried some workarounds:
1. Use timeout parameter of main process to catch the exception.
-> timeout function does not work: Even if I choose 1s (parameter lTime = 1) at normal process duration of 9s, the main process is not interrupted and I don't get any error code -> It takes 9s.
2. I tried to communicate with the programmer not via dll but directly via serial interface (commands according user's guide).
-> Via USB it works with all commands (with / without checksum). But I can only use commands without checksum ("Hello", Get Progress Status) when I want to communicate via RS232 (that's my use case).
So, at the moment, my only solution is, to change my whole setup (switch from RS232 to USB). But that requires a lot of work and effort. (It's a setup integrated into an inline production line).
Do you have some advice, additional ideas for workarounds or the solution of the underlying problem / problems of the workarounds?
Thank you!
