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.

Name Description
Master lock The slave station has been parameterized by another master.
Parameter fault The last received parameter data from the Master Unit have been rejected. The parameter

Invalid slave response The slave has returned an invalid response to a Master request message.
Function Not supported The Master Unit has sent a message to the slave station, which is not supported by the sta-
tion.
Extended diagnostics The diagnostics message returned by the slave station contains extended diagnostics, i.e. it
contains more than the mandatory 6 bytes.
Configuration fault The last received configuration data from the Master Unit have been rejected. The configura-
tion data in the slave station differ from the configuration sent by the Master Unit.
Station not ready The slave station is not yet ready for data transfer (the parameters data and the configuration
data have been accepted).
Station not existent The slave does not respond to any of the request messages sent by the master. If set the
diagnostic bits contains the state of the last diagnostic message or the initial value.
Slave deactivated
When set is indicates that the slave station has been disabled (i.e. using the STOP FINS
command). The slave station is allocated to the Master Unit, but removed from cyclic pro-
cessing.
Sync mode
When set to ON, the slave station has been set to the Sync mode, using the global com-
mand.
Freeze mode
When set to ON, the slave station has been set to the Freeze mode, using the global com-
