Transaction Editor
The Transaction Editor can be used to edit the individual Frame Objects of a Transaction. The same
settings are also available in the Parameter Section of the Main Window, however the Transaction Editor
presents the Frame Objects in a more visual manner.
To edit the value of a parameter, click on it and enter a new value using the keyboard. When editing
transactions which are based on pre-defined commands, certain parts of the transaction may not be ed-
itable.
The File-menu features the following entries:
Example:
The transaction created in this example are built up as follows:
The first byte holds the STX (0x02) followed by two bytes specifying the length of the data field
(in this case 8). The next 8 bytes are data and since this is a ‘query’-transaction, the data is to be
fetched from the Output Area which starts at address location 0x202. No swapping will be per-
formed on the data. This is followed by a two-byte checksum. The checksum calculation starts
with the second byte in the transaction.
The transaction ends with a byte constant, the ETX (0x03).
