To save a slave reponse message to a file:
1. See Section 3.4.2 “Save” and Section 3.4.3 “Save As”.
3.5.4.3 SLAVE RESPONSE FRAMES FIELD ELEMENTS
This section describes the “Slave Response Frames” field’s two elements.
3.5.4.3.1 ID
The “ID” element displays the identifier byte that is compared to identifier bytes
received from the bus. The ID is entered without the upper two parity bits. Parity is cal-
culated and appended when the message frame is stored in the inernal buffer memory.
The acceptable range of values is 00 to 3F hex (0 to 63 decimal).
3.5.4.3.2 DATA
The “Data” portion of the “Slave Response Frames” field displays zero to eight-byte val-
ues, separated by spaces. This are the actual bytes sent over the bus in response to a
recognized ID.
3.5.5 Slave Response Message Controls
3.5.5.1 SAVE BUTTON
Clicking this button stores the selected message content highlighted in the “Slave
Response Frames” field (see the “Save” procedure in Section 3.5.4.2 “Developing
and Storing Response Content”).
3.5.5.2 ADD BUTTON
Click the Add button to add a new message to the “Slave Response” field
3.5.5.3 EDIT BUTTON
Allows the selected message in the “Slave Response Frames” field to be edited.
3.5.5.4 DELETE BUTTON
Clicking the Delete button deletes the content that is highlighted in the “Master Frames”
field. (see the “Delete” procedure in Section 3.5.4.2 “Developing and Storing
Response Content”).
3.5.5.5 CLEAR ALL BUTTON
Clicking this button clears the both the contents of the “Slave Response Frames” win-
dow and the internal buffer memory. The buffer status is updated to show no used bytes
and bytes remaining.
3.5.6 Checksum Group
The checksum value is computed at send time. Selecting one of the
option buttons in the “Checksum” group, shown at right, determines
the type of checksum that will be calculated for all transmitted
master message frames, highlighted in the “Master Frames” field.
• classic – The checksum includes all data bytes.
• enhanced – The checksum includes identifier byte and all data
bytes.
• forced – (Enabled only in Debug mode.) The last byte in the message string is
sent in place of the calculated checksum. This is useful in checking master error
handling.
