Network Utility
Network Utility is part of the OMNI software suite and is used to view the configuration settings of
the DE module and to upgrade the DE module firmware (Figure 2-). Although the IP Addresses of
the DE Module can be modified, the program cannot be used to modify the remaining DE module
configuration settings. This must be completed through OMNICONNECT, although some of the
settings required to establish communications can be modified from the flow computer front
panel.

OMNI Modbus Tester
The OMNI Modbus Tester is a Modbus Master that can test a device that implements a Modbus
slave protocol, such as an OMNI flow computer. The tester can communicate using Modbus over
TCP, RTU or ASCII protocol. The register addressing can be Logical (1 float register is 4 bytes),
Register (two consecutive 16-bit registers are combined to make 1 float) or Modicon compatible
(two consecutive 16-bit registers are combined to make 1 float and the float bytes are swapped
from 'aa bb cc dd' to 'cc dd aa bb').
The tester supports all the major function codes as well as user-defined function codes. It also
supports a wide range of data types including Booleans and strings. You can repeat
transmissions of one register with a delay and set up a list of registers for one transmission or
repeated transmissions based on continuous, number of times, or over a date/time range.
