Gateway Status Data in Upper Memory

The gateway places useful status data in dedicated upper memory locations in its
internal database. The Data Map functionality of the gateway can be used to map
this data into the normal user data range of the gateway's database (registers 0
through 3999). It can be accessed by remote devices, such as HMIs or
processors. See Using the CommonNet Data Map (page 25).

3.3.1 General Gateway Status Data in Upper Memory

The following table describes the contents of the gateway's general status data
area.
Register Address
4000 through 4001
4002 through 4004
4005 through 4009
4010 through 4014
4015 through 4019

3.3.2 Protocol-Specific Status Data in Upper Memory

The gateway also has upper memory locations for protocol-specific status data.
Information about upper memory addresses where the gateway places status
data for its protocol drivers can be found in the Diagnostics sections of the
protocol chapters:
