2. Pre–assignment 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.

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.

The PLC–SPL signals are in DB18 and are sub–divided into

1. Parameterization part, and

2. Data area/status.

Parameterization part

The SPL_READY = TRUE signal indicates that the commissioning phase has

been completed, i.e. if a crosswise data comparison error has occurred, the basic

program sends a "STOP D/E" to all the axes.

For crosswise comparison error:

0 = external STOP D

1 = external STOP E
