Parameterizing example:
-- $MA_SAFE_CAM_PLUS_OUTPUT[0] = 04010101H
=> the SGA "SN1+" can be evaluated in the SPL using the system variable
$A_INSI[1].
Programming example:
; copying an SGA from the internal SPL interface into the ext. SPL
interface
N1010 IDS = 01 DO $A_OUTSE[1] = $A_INSI[1]
These system variables can only be read by the user program.
System variable $A_INSE[1...192]
The system variables $A_INSE contain the input circuit of the NCK--SPL.
System variable $A_INSED[1...6]
Image of the safety input signals (external NCK interface).
$A_INSED[1] corresponds to $A_INSE[1...32]
$A_INSED[2] corresponds to $A_INSE[33...64]
$A_INSED[3] corresponds to $A_INSE[65...96]
$A_INSED[4] corresponds to $A_INSE[97...128]
$A_INSED[5] corresponds to $A_INSE[129...160]
$A_INSED[6] corresponds to $A_INSIE[161...192]
System variable $A_INSID[1...6]
The status signals of the NCK monitoring channel can be evaluated in the NCK--
SPL in a double--word--serial fashion using this system variable:
$A_INSID[1] corresponds to $A_INSI[1...32]
$A_INSID[2] corresponds to $A_INSI[33...64]
$A_INSID[3] corresponds to $A_INSI[65...96]
$A_INSID[4] corresponds to $A_INSI[97...128]
$A_INSID[5] corresponds to $A_INSI[129...160]
$A_INSID[6] corresponds to $A_INSI[161...192]
These system variables can only be read by the user program.
System variables $A_OUTSE[1...192]
The system variables $A_OUTSE contain the outputs of the NCK--SPL.
