Data exchange between NCK -> PLC
$A_IN[1..8] -> DB10.DBB60
$A_IN[9..40] -> DB10.DBB186..189
$A_OUT[1..8] ->
DB10.DBB64
$A_OUT[9..40] ->
DB10.DBB190..193
$A_OUT variables can be written in the NC program
e.g. $A_OUT[n] = 1
Data exchange between PLC -> NC
$A_IN[1..8]
->
DB10.DBB1
$A_IN[9..40]
->
DB10.DBB123..129
$A_OUT[1..8]
->
DB10.DBB6
$A_OUT[9..40]
->
DB10.DBB130..141
$A_IN variables can be read in the NC program
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.
