Dear all,

I'm evaluating the EPICS OPC device support version 3.8.0.1 to read and
write data to a SIEMENS PLC (http://www-csr.bessy.de/control/SoftDist/O
PCsupport/).

Reading the documentation that can be found here:
http://www-csr.bessy.de/control/SoftDist/OPCsupport/download/readme3.8.
0.1.html#cont_14

It seems that array record types (i.e. aai, aao) are not supported (but
are mentioned in "opcDbg: OPC browsing and debugging" section).

Looking at source code (devOpc.c @ row 63) instead it seems that aai
and aao are both supported.

Which is the status of the EPICS OPC device support? Are array records
supported?

Thanks for your help.

Cheers,

Luca
