Global State Field
Bytes 8 to 71 contain the Global State Field registers. This field contains status information
of the PROFIBUS DP system. The input area mapping of the Global State Field is shown in
the table below.

8 Global_bits BOOL GLOBAL-BITS Global error bits, for a detailed description
of each bit and its meaning, see table
below
9 DPM_State SINT PROFIBUS DP Master State Main state of the PROFIBUS DP master
system
00hex: OFFLINE
40hex: STOP
80hex: CLEAR
C0hex: OPERATE
10 to 23 Reserved[14] SINT(14) Reserved Reserved, 14 Bytes
24 to 39 Sl_cfg[16] SINT(16) =
BOOL(128) Slave Configuration Bit Array 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
40 to 55 Sl_state[16] SINT(16) =
BOOL(128) Slave State Bit Array 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
56 to 71 Sl_diag[16] SINT(16) =
BOOL(128) Slave Diagnostics Bit Array 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
