Global State Field

The 64 byte Global State Field is available to the user program via the input area of the

master module. This field contains status information of the PROFIBUS-DP system. It

always begins at byte offset 8 of the input area. The input area mapping of the Global State

Field is shown in the following table.

GLOBAL-BITS

Global error bits, for a detailed

description of each bit and its

meaning see table below

DPM_State

SINT

PROFIBUS-DP

Master State

Main state of the PROFIBUS-DP

Master system

00hex: OFFLINE

40hex: STOP

80hex: CLEAR

C0hex: OPERATE

Err_rem_adr

SINT

Error Source

0 ... 125 Error detected with a

Slave device

255 Error with Master.

Err_event

SINT

Error Event

Error number, use the Err_rem_adr

value to determine if the error

occurred with a connected slave or

the Master itself. See error

numbers in table below.

12 to 13

Bus_err_cnt

INT

Bus Error Counter

Number of major bus errors.

14 to 15

Time_out_cnt

INT

Time Out Counter

Number of bus time outs.

24 to 39

Sl_cfg[128]

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.

"0" the slave is not configured in

the master

40 to 55

Sl_state[128]

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. "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[128]

BOOL(128)

Slave Diagnostic Bit

Array

If the Sl_diag bit of the

corresponding slave station is

logical "1" latest received slave

diagnostic data are available in the

internal diagnostic buffer. This data

can be read by the user with a

message. "0" since the last

diagnostic buffer read access of

the HOST, no values were change

in this buffer
