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.
IETG 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 Appendix
D
, Modbus Data Registers, 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.
