SCADA ADDRESS TABLE
The MMS SCADA address table controls the mappings between SCADA protocol address and the network
location of the RTU using that address. The address of each packet is checked against this list to
determine if it should be sent on the legacy radio network, or sent on the Aprisa radio network.
If a SCADA RTU address that is not present in the list is encountered, the Aprisa SR+ will automatically
learn which interface to use for this address by trying each interface in turn. A user may choose to create
static entries (or change existing dynamic entries to static) to remove this learning step and ensure that
the network always has consistent response times.
The following table shows the valid address ranges for the SCADA protocols:
