*Address

The address is used to specify the
Tank/Sensor/Input /Relay … Number to
be used in the poll. For some data
types the address has no meaning and
should be set to 1.
Veeder-Root Tanks / Sensors … are
numbered from 1. The maximum tank
number is 12 and the maximum sensor
number if 64.
When zero is used as the value of the
address then (in most cases) the driver
polls for all Tanks/ Sensors belonging
to that data type. This is discussed in
the Advanced Topics Section.
0, 1, 2, 3…
Length

Length of Map Descriptor
The length is used to tell the driver how
many elements of the Data Array are
under the control of the Map Descriptor.
This is important because the driver
uses the length to, for example, clear
Data Array elements when a
Tank/Sensor has no alarms.
