To display I/O data values for a device, select Profibus DP slave configuration from the drop-down list.
Two pull down lists show the input/output data values:
-
The %IW area field displays the input data list for the device selected, with the symbol and the associated value for each data item.
-
The %QW area field displays the output data list for the device selected, with the symbol and the associated value for each data item.
-
The field of the Edit %QW area is used to enter the value of a %QW data item.
-
The Format area field indicates the type of display for each data item:
NOTE: Forcing is not authorized for %IW and %QW language objects.
The PLC switching to STOP mode makes the module’s fallback values appear in red.
This window shows all the diagnostics information for a device. By selecting a device from the Profibus DP slave configuration list, its diagnostics appear in the Profibus DP diagnostic data window.
The data displayed corresponds to a new diagnostics. When a device is selected from the list, the addressed module automatically undergoes diagnostics.
In all cases of diagnostics, the first six bytes are standardized and displayed. If a slave requires more than six bytes of diagnostics, the data is displayed in the window and can be accessed using the scroll bars.
