For the above sensor address maps, these addresses only correspond to a sensor that is configured in the Sensor 1 spot in the Gateway configuration. The 0 value can range from 0 - 9 which stands for Sensors # 01 to 10.
Interpreting Modbus Data
Modbus does not have a mechanism for reporting the validity of data. What happens if the gateway loses its connection to the Veeder Root Device? After a timeout period has elapsed the gateway will regard the data it had read previously as unreliable.
The remote data client will see the value 65535 (-1, configurable) in the registers that contain unreliable data. In other words, rather than serve the old (possibly obsolete) data, the gateway serves a value that clearly identifies that the data is invalid.
Some values have been encoded as IEEE754 format floating point numbers. These values use 2x 16bit registers. They are clearly identified in the Modbus Map. Since Modbus does not support floating point numbers, all other values are served as whole numbers.
