16 Points per STIMV IOP

The STIMV IOP contains sixteen AI points which are read/write accessible from the PMM and upper network components as shown in Figure A-3. Figure A-3 shows four SMV 3000 transmitters with four PVs each connected to IOP points 1, 5, 9 and 13, respectively.

You can mix single PV transmitters with multivariable transmitters within the given one to eight or nine to sixteen IOP boundary, but all PVs for a multivariable transmitter must be allotted to consecutive slots within a given IOP boundary. While a multivariable transmitter is physically connected to only one slot, the adjacent slots are allocated for the other PVs of the transmitter and they can not cross over or wrap around the IOP boundaries.

Note that points include the usual IOP PV processing parameters such as alarm limits, alarm hysteresis, PV clamping, and engineering unit conversion
