1 : DATA EX ERROR
2 : WAIT CONFIG
3 : WAIT PARAM

5 : DISABLED
DATA EXCHANGE
Data Exchange mode. The parameterisation and configuration have been accepted and the slave
is exchanging user data with the master.
DATA EX ERROR
Data Exchange mode, as above, but with read/write error(s). This indicates that at least one of the
parameters being read or written is failing, for example writing a value out of range.
WAIT CONFIG
Waiting for configuration. The parameterisation from the master has been accepted and is now
waiting for the Master to send valid configuration data.
WAIT PARAM
Waiting for parameterisation. The slave has detected communications at a valid baud rate and is
waiting for the master to send valid parametrisation data.
BAUD SEARCH
The slave has not detected valid communications.
DISABLED
The interface is disabled. The reason for this is given by the FAULT parameter.
INT DIAGNOSTIC
