All error codes listed above result in an error code of 2.

Any time the error code is non-zero, the DEM error (ER) bit is set.
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 of Send Data
(Bytes) field, starting with the low byte of the first word. If the Size of Send
Data 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 DEM control block
when the rung is accepted. To update the Send Data display with the current
values stored in the DEM control block, 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 shows 58 bytes of receive data, starting with the low
byte of the first word. To update the Receive Data display with the current
values stored in the DEM control block, click on the Refresh button.
