Setting Up the RTU to Retrieve the
Current Data through Modbus
Following monitor activation, you must program the RTU with the
appropriate Modbus register addresses corresponding to the current
entity and monitor data you want to retrieve from the monitor. ADS
also recommends verifying that the RTU is retrieving the desired
output data shortly following monitor activation.
Note: The Telog Ru-33 does not require programming
with the Modbus register addresses to ensure it retrieves
the correct data. However, consider verifying whether the
Telog unit is successfully retrieving data following monitor
activation and Telog connection.
Designating the Data for Retrieval
Use the appropriate software application supporting the RTU to
designate the entity and monitor data you want the unit to retrieve
for the SCADA or other process control system. Refer to Chapter
9, Modbus, to view the entity and monitor data available for
retrieval and to determine the associated register addresses required
for obtaining the selected data.
Verifying the Modbus Output Data
Perform the following to verify the accuracy of the Modbus output
values, when applicable:
1. Verify that the monitor has been activated, the RTU has been
programmed to retrieve the desired data, and the applicable
Modbus application has been launched.
