What software we need will be useed and buy for connect PLC and VAX ? (We
used BASEstar Open + DCM)

[Wizard]

The OpenVMS Wizard would check both with the vendor of the PLC or
directly wwith Siemens Simatic, and with the BASEstar package
hardware support listings. The Siemens Simatic does not appear
to be formally and directly supported with BASEstar Open, though
there does appear to be at least one third-party connection for
the Siemens MPI adapter connection and BASEstar Open via EIA485
(RS485) multidrop.
