Diagnostics User Interface
The Generic Slave Device DTM provides a Diagnostics User Interface to dis-
play diagnostics data sent by the slave device to the PROFIBUS Master Unit.
In general a slave device can send two type of diagnostics.
Basic Diagnostics
• Basic Diagnostics
The first six bytes of each diagnostic message sent by a slave device
contain mandatory status and error flags. The flags are defined by the
PROFIBUS standard. Refer to the CS1/CJ1W-PRM21 Operation Manual
(W409-E2-
@)
for a detailed overview of diagnostics. The basic diagnos-
tics information is displayed in the Diagnostic tab of the Diagnostics User
Interface.
Extended Diagnostics
• Extended Diagnostics
Depending on the type of slave device, it may additionally send Extended
diagnostic bytes in a format defined in the PROFIBUS standard. The
Extended diagnostics usually contain device specific diagnostics informa-
tion. The Extended diagnostics information is displayed in the Extended
Diagnostics tab of the Diagnostics User Interface.
Updating the Diagnostics
The Diagnostics User Interface contains two tabs. It also contains an
Update
button, which will - when pressed - refresh the diagnostics data, by retrieving
it from the PROFIBUS Master Unit. A Green LED indicator in the lower left
corner will indicate whether or not the device is on-line.
Diagnostics Tab
The Diagnostics tab displays basic diagnostics for the slave. An example of
the Diagnostic tab is shown below. The diagnostics information is displayed
as red and green LED indicators. Red LED indicators refer to error events.
Green LED indicator refer to status situations.
