About Number Of PVs The number of PVs that a given SMV 3000 transmitter supports is

 

 

determined upon its database configuration. Using the SCT 3000, SFC or

 

 

through the universal station, the SMV can be configured to select (or turn

 

 

ON) any number of PVs for broadcast to the IOP. The PV1 input is

 

 

always selected for broadcast but you can configure it to also include

 

 

secondary variable data. You can select PV2, PV3, and PV4 for broadcast

 

 

(by turning them ON or OFF) as applicable for the given measurement

 

 

application. Table A-1 shows what PVs represent in the SMV 3000

 

 

transmitter. See PV Type in subsection 6.5 for details in selecting PVs for

 

 

broadcast using the SCT 3000.

 

 

See DE_CONF parameter in subsection A.5 and DE_CONF Changes in

 

 

subsection A.6 for more information on selecting PVs using the universal

 

 

station.
