Siemens SINUMERIK 840D sl Function Manual page 242

Connecting Sensors/Actuators
7.3 Safe programmable logic (SPL)
Limitations
The language commands SIRELIN, SIRELOUT and SIRELTIME may not be used
in synchronized actions.
The language command SIRELAY may only be used in synchronized actions of
the SPL (SAFE.SPF). The connection must be specified beforehand using the lan-
guage commands SIRELIN, SIRELOUT and SIRELTIME.
Example
Example of an Emergency Stop implemented using NCK–SPL in SAFE.SPF:
DEF
N10 DEFINE IE_NH_E
N20 DEFINE IE_NH_Q
N30 DEFINE MI_NH_Q
N40 DEFINE MI_C_ABW
N50 DEFINE MI_A_ABW_A
N60 DEFINE MI_A_ABW_S
N70 DEFINE M_STATUS_1
