Modbus
(Advanced Only)
Modbus RTU over RS485, 127 addressable units / 2-wire network, 9600 baud, long integer and single
precision IEEE754 formats; retrieve: flow rate, job totalizer, grand totalizer, alarm status and battery
level; write: reset job totalizer, reset grand totalizer
Data
Configuration
and Protection
Two 4-digit user selectable passwords; level one password enables Job Total reset only, level two
password enables all configuration and totalizer reset functions (Not Applicable on solar powered
units)
Totalizer Operation
Common
Functions
Monitors contain two totalizers: Job and Grand The user can enable/disable the Grand Totalizer
function If Grand Totalizer is enabled, it shares the 7-digit display line with the Job Totalizer –
dwelling between Job and Grand Grand Totalizer rollovers are displayed with a Count value that
increments at each rollover Totalizers are automatically backed up into non-volatile FLASH memory
every 20 minutes and prior to battery expiration; manually via keypad or when signaled via
Modbus (Advanced Model only)
