Send Data Tab
The Send Data Tab provides a convenient way of viewing and
entering in data to be sent along with the explicit message command.
The data is shown in byte format with a selectable radix of either
Decimal or Hex/BCD. The display only shows the number of words
that are defined in the Size in Words (Send Data) field, starting with
the low byte of the first word as defined in the Data Table Address
(Send Data) field. If the Size in Words is zero, then no data is
displayed. You can also change the data being viewed, but only when
offline or during an online edit. Click on the data and enter in a byte
value based on the current radix (0 to 255 for Decimal and 0 to FF for
Hex/BCD). The changed data gets copied to the Send Data data table
file when the rung is accepted. To update the Send Data display with
the current values stored in the Send Data data table file, click on the
Refresh button.
Receive Data Tab
The Receive Data Tab provides a convenient way of viewing the data
that is returned by the target device in response to the explicit
message command sent. The data is shown in byte format with a
selectable radix of either Decimal or Hex/BCD. The display only
shows the number of words that are defined in the Size in Words
(Receive Data) field, starting with the low byte of the first word as
defined in the Data Table Address (Receive Data) field. If the Size in
Words is zero, then no data is displayed. To update the Receive Data
display with the current values stored in the Receive Data data table
file, click on the Refresh button.
