Profibus Card Profibus Diagnostic Telegram and Flag
7 Profibus Diagnostic Telegram and Flag
The Profibus Card supports external diagnostics. The following telegram will be sent to the
Master if the soft starter trips or if a parameter is changed at the soft starter.
Diagnostic Telegram Data Structure
Byte 0 User diagnostic length (Always set = 3)
Byte 1
Trip Code
Byte 2 Changed parameter number
Profibus Trip Code
When the soft starter trips, a diagnostic flag is set at the Master and the trip code is
reported in Byte 1. When the soft starter is reset, the diagnostic flag and trip code data are
reset = 0, provided the trip condition does not still exist (see Trip Codes on page 9).
Changed Parameter Number
If a parameter is changed via the keypad, the affected parameter number is reported in
Byte 2. When the Master reads or writes the changed parameter, Byte 2 is reset = 0.
A changed parameter number does not set a diagnostic flag.
8 Profibus Freeze Mode
The Profibus Card supports Freeze Mode.
In Freeze Mode, inputs are only updated with new data from the soft starter when another
Freeze action is carried out. An Un-Freeze action returns the device to normal operation.
9 Profibus Sync Mode
The Profibus Card supports Sync Mode.
In Sync Mode, commands to the soft starter are not processed until another Sync action is
carried out. An Un-Sync action returns the device to normal operation.
10 Profibus Clear Mode
If the Master sends a global Clear command, the device will send a Quick Stop command
to the soft starter.
