7.3 Safety Integrated with SPL
Program DB120 program excerpt:
DATA_BLOCK DB 120

STRUCT
END_STRUCT ;
BEGIN
END_DATA_BLOCK
When the NCK-SPL has been successfully started by the PLC (FC95)
processing of the PLC-SPL (FC96) is enabled in OB1.
Two more predefined blocks are integrated in FC97 – FC60 (Example blocks
can be requested from the hotline, telephone No. 0180-525 8000) and FC21
(basic program block – FB1/P3). Modifications must also be made to OB100 to
ensure perfect operation of the safe programmable logic.
The markers, outputs and inputs used in this example have been freely
selected according to the test set-up being used.
Chapter 7.3.3 contains an overview of the I/O (peripherals) and variables used.
The ASUB for the NCK-SPL must be saved in the standard cycle directory
(CST.DIR) under the name SAFE.SPF.
The Safety Integrated functions SBH/SG and the SI function "External STOPs"
are activated for the individual drives. External stops are a prerequisite for
using the SPL logic.
