Data Description
8.7 System variables
System variables $A_OUTSI[1...192]
The control signals of the NCK monitoring channel can be addressed from the
NCK--SPL using these system variables. Each of the system variables
$A_OUTSI[1...192] can be simultaneously assigned any one or several safety--
related input signals by using the axis--specific MD $MA_SAFE_xxx_INPUT.
Parameterizing example:
-- $MA_SAFE_VELO_SELECT_INPUT[0] = 04010204H
=> The SGE "SG selection, bit 0" is controlled in the SPL using the system
variable $A_OUTSI[36].
Programming example:
; SGA "cam 1+" (refer above) controls the SG selection
;
N1020 IDS = 02 DO $A_OUTSI[36] = $A_INSI[1]
These system variables can be read by the user program and written into by
SAFE.SPF.
System variable $A_OUTSID[1...6]
The control signals of the NCK monitoring channel can be addressed in the NCK--
SPL in a double--word--serial fashion using these system variables:
$A_OUTSID[1] corresponds to $A_OUTSI[1...32]
$A_OUTSID[2] corresponds to $A_OUTSI[33...64]
$A_OUTSID[3] corresponds to $A_OUTSI[65...96]
$A_OUTSID[4] corresponds to $A_OUTSI[97...128]
$A_OUTSID[5] corresponds to $A_OUTSI[129...160]
$A_OUTSID[6] corresponds to $A_OUTSI[161...192]
These system variables can only be read by the user program.
These system variables can be read by the user program and written into by
SAFE.SPF.
System variable $A_OUTSED[1...6]
The external status signals can be addressed by the NCK--SPL in a double--word--
serial fashion using these system variables:
$A_OUTSED[1] corresponds to $A_OUTSE[1...32]
$A_OUTSED[2] corresponds to $A_OUTSE[33...64]
$A_OUTSED[3] corresponds to $A_OUTSE[65...96]
$A_OUTSED[4] corresponds to $A_OUTSE[97...128]
$A_OUTSED[5] corresponds to $A_OUTSE[129...160]
$A_OUTSED[6] corresponds to $A_OUTSE[161...192]
These system variables can be read by the user program and written into by
SAFE.SPF.
