state field. The first row shows the Online master main state for example,

. The next row shows the collective status bits. An activated bit
is red. Further contents are given:

Device specific status bits:

This application updates the status online in the global state field. You can see
the diagnostic by double-clicking at a selected station address of a device. The
meaning of the shortcuts is listed below:
Collective Status Bits
TOUT
(TIMEOUT-ERROR) The device has detected an overstepped timeout
supervision time because of rejected PROFIBUS telegrams. This is an
indication for bus short circuits while the master interrupts the
communication. The number of detected timeouts is fixed in the statistic bus
information variable. The bit will be set when the first timeout was detected
and will not be deleted.
