$A_INSE / $A_OUTSE The external NCK input and outputs are assigned bytewise to the NCK-SPL in
NCK the following machine data
External NCK inputs
MD 10390 SAFE_IN_HW_ASSIGN[0] :
MD 10390 SAFE_IN_HW_ASSIGN[1] :
External NCK outputs
MD 10392 SAFE_OUT_HW_ASSIGN[0] :
MD 10392 SAFE_OUT_HW_ASSIGN[1] :
They are available in the form of system variables $A_INSE and $A_OUTSE
for the SPL program.
Configuration example:
The terminal block has the logical drive number 4 (acc. to the drive
configuration), the input module being used is inserted into slot 1 (sub-
module 1), the output module into slot 2 (sub-module 2).
This results in the following parameterization for the machine data above:
MD 10390 SAFE_IN_HW_ASSIGN[0] :
MD 10390 SAFE_IN_HW_ASSIGN[1] :
MD 10392 SAFE_OUT_HW_ASSIGN[0] :
MD 10392 SAFE_OUT_HW_ASSIGN[1] :
$A_INSI / $A_OUTSI The internal inputs and outputs of the SPL logic are assigned using the
NCK following machine data
Internal SPL inputs
MD36980...MD36990 :
The SGAs are output signals of the SI function and can be mapped to the
system variables $A_INSI[n]. These can, in turn, be read in the NCK-SPL and
used as inputs for the logic operations.
Internal SPL outputs
MD36970...MD36978 :
The SGEs are input signals of SI function and their values are supplied from
the system variables $A_OUTSI[n]. These can be written in the NCK-SPL.
Configuration example: Parameterized machine data as shown in the table
$A_MARKERSI In order to save intermediate states in the SPL logic, markers are defined.
These markers are available in the NCK in system variables $A_MARKERSI[n].
NCK
There is no connection with machine data.
Configuration example: Assignment as shown in the table
$A_TIMERSI In order to program timers in the SPL logic, timers are available in the NCK in
system variables $A_TIMERSI[n]. There is no connection with machine data.
Configuration example: Assignment as shown in the table
