Behavior after power on / mode change / reset
1. After the system has booted, the following Safety Integrated system variables
are assigned the value zero:
$A_INSE(D), not for F_DP communication
$A_OUTSE(D),
$A_OUTSI(D),
$A_MARKERSI(D),
$A_INSEP(D), not for F_DP communication
$A_OUTSEP(D),
$A_OUTSIP(D),
$A_MARKERSIP(D)
$A_INSI(D).
2. Preassignment of other variables before cyclic processing of the NCK--SPL
starts can be programmed in the same part program as the NCK--SPL itself.
To ensure that the pre--assignment instructions are only performed once, they
must use the following syntax:
As a result of the identifier IDS, the events "operating mode change" and "reset"
have no effect on the processing of the NCK--SPL.
3. Several boot instructions can be programmed in one block.
4. For the relevant FDP system variables, see Chapter 7.4.8 "Boot behavior of the
F_DP communication" and the following.
7.5.11
SPL data on the PLC side
The safe programmable logic of the PLC (PLC--SPL) is a sub--function of the
safety functions integrated in the SINUMERIK.
Signals
The PLC--SPL signals are in DB18 and are sub--divided into
1. Parameterization part, and
2. Data area/status.
Parameterization part
SPL_READY:
The SPL_READY = TRUE signal indicates that the commissioning phase has
been completed, i.e. if a CDC error has occurred, the basic program sends a
"STOP D/E" to all the axes.
