Re: Error database DTYP

[Carsten Winkler <carsten.winkler@helmholtz-berlin.de>]

Hi Antonio,

you need only one soft IOC (the one at the MicroBox). In your case you
have to run the OpcIocShell to have an interface between OPC and EPICS.
At Linux you only need channel access clients as caget, camonitor or
higher level clients. A standard soft IOC doesn't support the DTYP
"OPC". This is a special feature of the OpcIocShell.

Hope this resolves your problem
