The protective mechanisms that prevent changes to the NCK--SPL file and the

NCK--SPL instructions (statements) are only effective if

MD $MN_PREVENT_SYNACT_LOCK[0,1] is not equal to 0.

The machine construction OEM must ensure that the protective mechanisms are

activated no later than after the completion of the acceptance test and the values,

set in MD $MN_PREVENT_SYNACT_LOCK[0,1] are documented in the

acceptance report.

After commissioning has been completed, the access rights to the SAFE.SPF file

must be set to the correct access level for writing/reading/deleting access

operations (manufacturer or service).

As long as the protective mechanisms for the NCK--SPL have not been activated

(MN_PREVENT_SYNACT_LOCK[0.1] equal to 0), Alarm 27095 is displayed when

the crosswise data comparison between the NCK and the PLC starts. This alarm

can be acknowledged with the NCK key so that the SPL can be commissioned.

The SPL program must be addressed using upper case letters. Alarm 27097 is

output if this is not observed.

Starting the SPL

The NCK--SPL is active after the control has booted, if

1. the functions SBH/SG and "external STOPs" have been enabled for at least

one axis using $MA_SAFE_FUNCTION_ENABLE,

2. one of the NCK--SPL interfaces is used.

This means that an axis--specific SGE/SGA was parameterized at one of the

SPL interfaces using its assignment MD.

In this case, the "external STOP A" must be parameterized at the SPL interface for

all of the axes that use Safety Integrated.

NCK--SPL (SAFE.SPF) can be started in three different ways:

S Start via safety power on

S Start via PROG_EVENT

S Start via the PLC program
