Associated with: SCADAPack Modbus Realflo Outsations, and SCADAPack Modbus Realflo Analog Input points
The Source attribute is common to many Status displays. The attribute indicates the location at which an item resides. The information shown varies, depending on the type of item.
For SCADAPack Modbus Realflo Outstations, the attribute displays information in this format:
Set <Set Address>:OS <Controller Address>
For SCADAPack Modbus Realflo Analog Inputs, the attribute displays information in this format:
Set <Set Address>:OS <Controller Address>:Flow Run <Flow Run Number>:AI Source <Source Number>:Item <Item Number> (Address <Point Address>)
where:
- <Source Number> represents the type of Flow Run Source defined for the Analog Input Point
- <Item Number> represents the type of Flow Run Data Item defined for the Analog Input Point.
For information about either of the above properties, see Configure the General Realflo Analog Point Properties.
