bus is currently 0 for all records, so they are ignored by the parser. Also, Zone is a 1-based number.
Zone 0 is a special case that
denotes “self” or the RMA PLUS in this case. Using Zone 0 is agnostic of
changes to the Watbus logical address. If you wish to use the system configuration file to set your
Ethernet parameters, change the bus to 1 for each record and verify the elements in the value column.
Add records to the file as necessary keeping the following in mind:
•
Unless otherwise specified, all numeric fields are base 10 (decimal).
•
The file may contain a maximum of 2000 valid records.
•
There is currently a maximum of 500 unique data points per Watbus bus and zone.
•
Writing to the parameters in this example will require two resets. The first reset writes the new
value to the Ethernet object, the second reset uses the new value to initialize communications.
NOTE: There are other parameters that will behave this way.

Non-Volatile Memory
Software objects that contain non-volatile elements are stored in files in a protected partition of
memory on the NOR FLASH drive that cannot be accessed directly by users. Software tools such as
Dashboard may be used to modify these files indirectly.
Objects that have been changed are only saved to non-volatile memory after three seconds of inactivity.
This feature prevents pre-maturely wearing out NV memory due to constant writes. However, this also
implies that the user must wait at least three seconds before resetting the RMA PLUS to prevent losing
recent changes.
It is also important to note that since the protected volume (described above) and customer volume
exist on the same device, changes cannot be saved to non-volatile memory if the user has the NOR
FLASH drive mounted (locked).
Standard Objects
The RMA PLUS implements the following software objects. Conditional objects and / or instances are
highlighted in yellow.
