"Address and
Data"
Sets the trigger to an address or data pattern, or a combination of
both.
See
Remote command:
Slave Address
Sets the slave address to be triggered on. If you want to trigger only on a data pattern
and the address is not relevant, enable "Any Address".
To specify the slave address, set the following properties:
●
Set the length of the slave address: "7Bit" or "10Bit".
●
Toggle the trigger condition between "Read" and "Write" access of the master. The
read/write bit is the 8
th
bit of the first address byte of a frame.
●
Set the address of the slave device: enter the binary or hexadecimal address
value. You need an exact address, "X" bits (don't care) are not allowed.
Remote command:
Symbolic ID
If a label list with symbolic names was loaded and applied in the bus configuration, you
can select a symbolic name from the list instead of specifying the address. When you
select a name, the address fields are update with its address value.
Data condition
The data condition consists of the following settings:
●
Byte offset (position of the data pattern)
●
Length of the data pattern
●
Data pattern, see
If you want to trigger only on an address, and the data is not relevant, set all data bits
to "X".
Byte Offset ← Data condition
Sets the number of offset bytes to be ignored after the end of the address bytes. The
first byte of interest is the first byte after the offset bytes.
The minimum offset is 0
Bytes, the maximum offset is 4,095
Bytes.
Remote command:
Number of Bytes ← Data condition
Sets the number of full bytes you want to trigger on. Maximum 3 bytes are possible.
Note:
Entering data bits beyond the specified length of the pattern automatically
adjusts the "Number of Bytes" to include defined bytes.
