To activate the Debug Mode select the menu Online > Start Debug Mode. Then, mark a Slave (left
mouse click) and then the menu Online > Device Diagnostic to open the diagnostic window for this
Slave. Alternatively, double click on the symbol of the device to open this window. To end the Debug
Mode select the menu Online > Stop Debug Mode.
After the debugger has started HSyCon requests the state of all devices from the Master. If there is
an error on a device, the bus line to this Slave is displayed in red, otherwise it is green. HSyCon also
displays the letters Diag, if the device signals diagnostic information or the master holds diagnostic
information in its internal diagnostic buffer. This information is displayed in more detail if the
corresponding device in Debug Mode is selected with the mouse.
The diagnostic information of a DP Slave can be 6 to 100 (max. 244) bytes. The first 6 bytes are
standard diagnostic information (specification). The meaning of these 6 bytes is according to the
PROFIBUS specification and contains the Station Status 1, 2 , 3, the assigned master address and
the ident number of the Slave.
