In order to maintain an overview when analyzing a network, frequently only
certain messages or message groups need to be received or analyzed. For this,
the Receive module provides a filter function that makes it possible to display
only messages with certain Identifiers.
In order to reproduce this, first generate further messages in the Transmit
module either
|
by selecting of the menu point Edit | Insert Message
or |
|
|
by clicking on the button 
in the toolbar. |
For our tutorial it is sufficient if you only fill out the Identifier column
in the new lines. Generate for example five new messages with the Identifiers
0x15, 0x16, 0x24, 0x25 and 0x26, enter in the Count field the value "0"
and in the column Time a cycle time of 10 ms or load the file
Filter.txl. Now start cyclic transmission for all messages and view the result
in the Receive module in the Scroll- and Overwrite-mode. In order to filter out
certain messages here, either
|
|
select the point Functions | Filter from the
menu of the Receive module or |
|
|
click on the button 
in the toolbar. |
Then the following dialog appears for setting the message filter. In the
default setting, the Receive module first displays all messages. Now click Reject
All, in order to mask all identifier.
In the next step the filter is opened for certain IDs. To accept ID 0x14 select HEX
and enter "+14" in the ID (express selection) field and press return.
The IDs 0x24 - 0x26 are moved to the list of accepted IDs by entering the
command "+24,26". Press the OK button to activate the new filter
settings to receive only messages with the selected identifiers.
For more complex tasks it is also possible to start several Receive modules with
different filter settings in each case. Filter settings are saved together with
the whole configuration via the Control panel.
Before continuing the tutorial open the filter dialog again and press the Accept
All button to receive all messages.
