Chapter 3 Bind Function Blocks with I/O
You can download when logic is enabled or disabled. If you
download logic when logic is enabled, the download process occurs
as follows:
• The Function Block Editor checks to see if logic is enabled in
the device.
• If the logic is enabled, you are asked if you want to disable
logic. If you:
– Select No - the logic is not downloaded to the device and an
error message displays.
– Select Yes - the logic is downloaded to the device.
• If logic was enabled before you downloaded, when the
download is complete, you are asked if you want to re-enable
the logic. If for some reason the screen format cannot be
downloaded into the product, an error message will be
displayed and the screen format will not be saved. If logic was
not enabled before you downloaded, you are not prompted to
enable or disable the logic.
• When the download is complete, you are notified that the
download was successful. Note that if the master is currently
scanning the device to which you are downloading, you must
first access the DeviceNet scanner's scanlist to remove the device
from the scanlist. If this new logic results in different connection
sizes, you must adjust the master as follows:
– Put the master in Idle mode (This may mean turning a
processor's key switch to Program.)
– Access the device parameter’s to change the size of the
connections.
– Download the device to the scanlist.
– Click the Edit I/O Parameters button and verify the Rx and Tx
size corresponds to the new connection size.
– Put the master in Run mode for normal operation.
You can click the Cancel button anytime during the download process
to abort downloading the logic to the device. If you click the Cancel
button, an error message displays and neither old logic nor new logic
exists in the device. You must let the download complete for logic to
be contained in the device.
If logic is enabled during the download process, once the download is
complete, online animation starts. You see the real time values on the
wires connecting the elements. If logic is disabled, there is not any
activity; the current state of connections is displayed and inputs can
be changed, but online animation does not start.
