If you see a value of 0x000 press the F5 key on your keyboard to update the web page. When
you see the 0x001 value then your HES is successfully communicating with your MODBUS
Host via Ethernet (see Table 2.3).

Now you can verify that HART data is passing from your HART device, through the HES, and
on to your MODBUS/TCP Host (even though your HART Field Device is not connected to your
process).
Go to the page entitled Field Device HART Status and observe the registers for Channel 1. You
should be able to see status information for Channel 1, Device 1 similar to the Table 2.4.

Channel 1, Devices 2 to 16 are not polled.
Note that the Field Device Status in this example shows a code of (4) for More Status Available
and a code of (7) for Device Malfunction. This data is being transmitted by the HART Field
Device and is being successfully read by the HES. To ensure that this data is being
successfully passed along to your MODBUS/TCP Host you will have to use your MODBUS/TCP
Host to read Register 4225. Please see Figure 2.5 and notice that register 4225, bit position 4
shows a 1, and register 4225, bit position 7 also shows a 1. This proves that the HART data is
being successfully passed from your HART Field Device, through the HES, and on to your
MODBUS/TCP Host without error.
