Chapter 2 About the RdbmsNetwork
The RdbmsNetwork driver shown below, is a “non field bus” type driver that uses a network architecture similar to other NiagaraAX drivers.
The RdbmsNetwork driver has many properties and extensions in common with other "field bus” type Network Drivers. However, there are several distinctive RdbmsNetwork driver characteristics. The following list briefly notes some of the distinctive points of the RdbmsNetwork driver:
- The RdbmsNetwork Driver Component Location
There is not a separate RdbmsNetwork driver component palette. In addition to being available from the Driver Manager view shown below, the driver is also located on each of the individual rdb database module palettes.
When you add the RdbmsNetwork driver component from the Driver Manager view, using the dialog box, the component is placed under the Station "Drivers" node.
NOTE: Starting in NiagaraAX-3.4, appropriately-licensed NiagaraAX PC based Supervisor stations support SqlServer, Oracle, Db2, MySQL, and HsqlDb databases. For embedded JACEs, the HsqlDbDatabase is the only database that is supported.
- Rdbms Point Device Extension
The Rdbms point device extension is unlike point device extensions associated with other driver types. This point device extension uses the Rdbms Point Query component to filter database records to provide candidate records for proxy points. Refer to About the Rdbms Point Device Extension for details.
- RdbmsNetwork Tuning Policies
The RdbmsNetwork does not have a "Tuning Policies" component. However, some measure of tuning is provided with the "Rdbms Worker" component shown below and available under individual Rdbms device drivers).
