6. Configuring the Gateway
6.4. Transferring a Configuration to the Gateway
When using AbcConf, you can transfer the configuration you are editing to the gateway at any time.
Choose “Download configuration to ABC-LUFP” from the “F
ile”
menu or click on the button, in the AbcConf toolbar.
AbcConf initializes a check test of the gateway type.
During this
test, the PC should not carry out any other operations, as
this could lead to AbcConf apparently freezing up and slow
down the PC’s general operation for several minutes!
The
test then continues and the PC returns to normal running speed.
Once this test has finished, a window called “Download” opens
and a progress bar shows the state of progress for the transfer of
the configuration to the gateway. You must never interrupt this
operation, otherwise you will have to start it again from the
beginning.
Check that the transfer has been correctly carried out: LED
s
GATEWAY should be flashing green.
If this LED is flashing red/green, save the configuration you were editing, open the file containing the default
configuration for LUFP7 gateways, then transfer it to the gateway. This will restore it to a known initial state. You
can then continue with the configuration you were transferring, and make any corrections which may be
necessary.
If the gateway and its master DPM1 are both connected via a Profibus-DP network, LED
q
FIELDBUS DIAG will begin
to flash red at a frequency of 1 Hz if changes have to be made under SyCon. This occurs if you change the total size
of the input data and/or the total size of the output data exchanged with the Modbus slaves.
6.5. Monitoring the Content of the Gateway’s Memory
One of the main commands that you will need to use when setting up the gateway is the command allowing you
to read the contents of the gateway’s memory and to display it in a window used for this purpose. This will be
particularly useful when you are working on your PLC configurations and applications. However, it only shows
data from the “Data” and “Preset Data” fields configured in the “Query” and “Response” elements of just one of
the Modbus slaves, plus the content of the gateway’s two reserved registers, located at memory addresses
16#0000-16#0001 (gateway status word) and 16#0200-16#0201 (Profibus-DP master command word).
To monitor the content of the gateway’s memory, start by selecting the node corresponding to the Modbus slave
whose data you wish to view, then choose “Monitor” from the menu whose name corresponds to the name of the
previously selected node. A monitoring window then appears. The sample window shown at the top of the next
page corresponds to a view of the contents of the memory exchanged, using the gateway’s default configuration,
with the “TeSys U n°1” motor starter.
