The newly received diagnostics can be viewed, by clicking with the left mouse
button on the LED indicator, indicating diagnostics. The mouse pointer will
change in to a hand icon, when positioned over the LED indicator.
Clicking the LED indicator with the left mouse button has the following effects
• The address of the associated slave device will be displayed in the Slave
Diagnostics Data box in the lower half of the window.
• The standard diagnostics flags of the associated slave device will be dis-
played. LED indicators representing a status are coloured green, LED
indicators representing a potential problem are coloured red.
• The colour of the LED indicator for the specific slave device in the Slave
Status Flags box will change colour, if no new diagnostics is available, i.e.
a yellow LED will turn to green.
• The New Diagnostics Received LED indicator in the Slave Diagnostics
Data box will be set to ON.
Note If the Auto-Update refresh mode has been selected, the New Diagnostics
Received LED indicator, will be ON only during one update cycle, provided no
new diagnostics are received after displaying.
The standard diagnostics for a slave device displayed in the Slave Diagnostics
Data box can be used to
• Troubleshoot the device, the configuration or the network connection
Troubleshooting the device and the connection is discussed in section 4-
2-2 Troubleshooting the Network using CX-Profibus.
• Determine the status of the slave device
• Determine if the slave device has reported extended diagnostics
If extended diagnostics have been reported to the Master Unit, the
Extended diagnostics received LED indicator will be on.
Refer to section 4-2-2 Troubleshooting the Network using CX-Profibus for a
discussion on the errors reported by the slave and how to correct them.
Since all slave devices will have to return their status in the diagnostics mes-
sage after parameterization, all the LED indicators associated with the slave
devices allocated to the Master Unit, will indicate received diagnostics right
after network startup.
If all slave devices have established I/O data exchange with the Master Unit,
this information may be less relevant. To detect new diagnostics, received dur-
ing I/O data exchange, the user can clear all current new diagnostics flags by
pressing the Clear Diagnostics button in the window, thus making it easy to
spot newly received, more relevant diagnostics afterwards.
Note Pressing Clear Diagnostics button will cause all yellow LED indicators to turn
green.
