For pulling data to office use from a PLC is ok.
But protocols have a tendency to be used in other ways than originally
designed for.
I've stopped several integration projects the last couple of years,
where the PLC-programmers wanted OPC (DA). they went live with
proprietary socket protocols instead, with great success.
PLC-programmers usually like OPC because they do not need to
do very much in order to make it work on their side.
Then it does not matter that it is a clunky protocol.
