7.3 Safety Integrated with SPL
Data exchange between NCK -> PLC
$A_IN[1..8]
$A_IN[9..40]
$A_OUT[1..8]
$A_OUT[9..40]
$A_OUT variables can be written in the NC program
e.g. $A_OUT[n] = 1
Data exchange between PLC -> NC
To implement data transfer for the test stop, a bit is allocated to each test stop
step. The further implementation can be seen from the above SPL program
excerpt.
