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/Ru-35 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.
2. Allow the monitor to log data for an appropriate
amount of time to obtain an adequate amount of data. Please
