Hello unclebump and thanks a lot for your input:
- The scout OPC server does not understand the indexing
- I never used the Visa drivers
- Yes, I agree, the NI OPC server is relatively poor and less robust than the Kepware. Another thing I noticed is that if I disconnect the physical link between the two PCs (Ethernet in my case) for more than 2 min, upon reconnection the tag engine on the LV side will not recover the communication (no more refresh of the tags and no error message! ie. tag quality is still good,...). To recover it I have to shutdown and restart the tag engine which is problematic because then all Vis that call the tag engine must be shutdown and restarted as well.
- I am using the latest version of the Siemens Scout, Etherne
t connection between the Siemens PC and the Labview PC.
- Like you I hope that the NI guys will take these requests into account.
Thanks again,
Christophe
