00hex: OFFLINE
40hex: STOP
80hex: CLEAR
C0hex: OPERATE

10 to 23 Reserved[14]

SINT(14)

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
