100 DeviceNet Explicit Messaging
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 shows only 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…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 Refresh.
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 Refresh.
