Hi all,
I have some problems with CaLab, necessary to integrate epics with a LabView interface. In particular now I have two big problems: 1) i don't understand how to use multiple field in the same CA. For example, my newport IOC includes some records of the type
mm4006:m11.HOMF
mm4006:m11.MOVN
etc...
CaLab Put.vi does not include the field. What do I do? if I put (for example) mm4006:m11.HOMF and mm4006:m11.MOVN as PV I find two distinct PVs... 2) I am trying to generate a monitor of the various IOCs. When starting LabView there is no PV (via CaLab info.vi). If I start the IOCs I see the PVs. However if I stop the IOCs, via command prompt (caget etc...) I do not see (obviously) the active CA, while via CaLab info.vi the CA are still active and give me the last values read. Even after a reset of PV, using CaLab_Disconnect.vi, I still see the active CAs with the last value read. Where am I going wrong?

Dariush
