Name Data
Type Signification Meaning if Bit is set
0 Ctrl BOOL CONTROL-ERROR Parameterization error
1 Aclr BOOL AUTO-CLEAR-ERROR Module stopped communication with
all slaves and reached the auto-clear-
end state.
2 Nexc BOOL NON-EXCHANGE-ERROR At least one slave has not reached the
data exchange state and no process
data will be exchanged.
3 Fat BOOL FATAL-ERROR Because of major bus error, no further
bus communication is possible.
4 Eve BOOL EVENT-ERROR The module has detected bus short
circuits. The number of detected
events is contained in the
Bus_error_cnt variable. This bit is set
when the first event was detected and
will remain set.
5 NRdy BOOL HOST-NOT-READY-
NOTIFICATION Indicates if the Application program
has set its state to operative or not. If
this bit is set the Application program
is not ready to communicate
6 Tout BOOL TIMEOUT-ERROR The module has detected an
overstepped timeout supervision value
because of rejected PROFIBUS
telegrams. It is an indication for bus
short circuits while the master
interrupts the communication. The
number of detected timeouts is
available in the Time_out_cnt variable.
This bit will be set when the first
timeout is detected and will remain set.
