ypeidra - S-series controllers only work with DeltaV v11 and above; there is no way to flash them to earlier versions of DeltaV. M-series controllers can be flashed to earlier versions of DeltaV if required. In order to take advantage of electronic marshalling and the other benefits of the S-series, your best bet is to upgrade to v11.
