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
