Data Array For Event-Oriented Data Channel - Bosch Rexroth ID 40 Manual

Bit 0 shows the status of the SLK operative flag, see Chapter 5.3.4. "SLK operative
flag")
Bits 1 and 2 show the current status of prefetch parameterization. The flags apply
both to the unbuffered prefetch function and the buffered prefetch.
Bit 1 Prefetch is parameterized:
'0' = no prefetch currently parameterized in system
'1' = at least one unbuffered prefetch or one buffered prefetch is parameterized
Bit 2 Prefetch parameterization is open:
"0" = prefetch parameterization is closed. If prefetches have already been
parameterized, these are executed once the system completes the PRECONNECTED
state.
'1' = prefetch parameterization is open. No prefetches are executed in this state.
Bit 3 Data transfer status (see Chapter 6.6 "'Open transfer' and 'Close transfer'
functions"):
'1' = "Open transfer" command executed
'0' = "Close transfer" command executed
The value of bit 3 does not return the accessibility of MDT data, since the transfer
channel function is no longer active. The bit remains for the sake of compatibility
with old applications. Bit 3 remains "0" when the "Open" and "Close" commands
are not used.
Bits 4 to 7 show the actual link state (see Chapter 5.3.1 "Actual link state"); this
value does not have to be entered separately in the prefetch.

Data array for event-oriented data channel

The SLK provides the data from the unbuffered prefetch starting with the third byte
of the event-oriented data exchange. If no prefetch was executed, the value of each
byte is zero.
