Modbus/EMUX Configuration and Diagnostics D-7
• Cryout address This represents the address of the server
that will receive the monitor events.
• Date and Time This represents the current date and time on
the EMUX clock.
System Tests
Selecting this submenu allows you to perform the following system
tests:
• Restart Emux Enter a 1 to restart the EMUX. Restarting
involves initializing all of the runtime variables and reloading
the firmware.
• Toggle CD to monitor Enter a 2 to set DTR on the EMUX
MODBUS port to control CD on the monitor. Pressing 2
repeatedly toggles the state. The first attempt may not change
the state of the pin, so you may have to press the key multiple
times to initiate the change on the monitor.
• Uart Loopback Test Enter a 3 to test the UARTs to which
the user is not connected for onboard diagnostics. The screen
will indicate PASS or FAIL for each UART.
Modbus Data Registers
This section contains tables providing Modbus registers. The first
table lists the Modbus data register addresses corresponding to the
entities for which the FlowHawk provides output data. The RTU
requests data from the monitor using the designated registers, and
the monitor (through the EMUX) sends the current entity data
representing those registers back to the RTU. Therefore, the user
must program the RTU with the appropriate registers based on the
type of data desired.
The second table lists the Modbus registers associated with more
general FlowHawk information.
