Explanation
Global error bits, for a detailed description of
each bit and its meaning, see table below
Main state of the PROFIBUS DP master system
00hex: OFFLINE
40hex: STOP
80hex: CLEAR
C0hex: OPERATE
Reserved, 14 Bytes
If the Sl_cfg bit of the corresponding slave is
logical '1', the slave is configured in the master,
and serviced in its states.
If '0', the slave is not configured in the master
If the Sl_state bit of the corresponding slave
station is logical '1', the slave and the master
are exchanging their I/O data.
If '0', the slave and the master are not
exchanging their I/O data. The values in
variable Sl_state are only valid, if the master
runs the main state OPERATE
If the Sl_diag bit of the corresponding slave
station is logical '1', the latest received slave
diagnostics data is available in the internal
diagnostics buffer. This data can be read by the
user with a message.
If the value is '0' since the last diagnostics
buffer read access of the slave, no values were
changes in this buffer
