4 Data Descriptions
4.4 System variable
These system variables can be read and written by the user program.
System variables The control signals of the NCK monitoring channel in the NCK-SPL can be
$A_OUTSID[1,2] addressed double-word-serial via these system variables:
$A_OUTSID[1] corresponds to $A_OUTSI[1...32]
$A_OUTSID[2] corresponds to $A_OUTSI[33...64]
These system variables can be read and written by the user program.
System variables Up to 64 external control signals can be used in the NCK-SPL via these system
$A_INSE[1...64] variables. The status of one byte of an NCK I/O input module can be assigned
to a block of eight system variables via
MD $MN_SAFE_IN_HW_ASSIGN[0...7].
$MN_SAFE_IN_HW_ASSIGN[0] -> $A_INSE[1...8]
$MN_SAFE_IN_HW_ASSIGN[1] -> $A_INSE[9...16]
$MN_SAFE_IN_HW_ASSIGN[2] -> $A_INSE[17..24]
$MN_SAFE_IN_HW_ASSIGN[3] -> $A_INSE[25..32]
$MN_SAFE_IN_HW_ASSIGN[4] -> $A_INSE[33..40]
$MN_SAFE_IN_HW_ASSIGN[5] -> $A_INSE[41..48]
$MN_SAFE_IN_HW_ASSIGN[6] -> $A_INSE[49..56]
$MN_SAFE_IN_HW_ASSIGN[7] -> $A_INSE[57..64]
For a precise description of MD parameterization refer to Chapter 4, "Machine
data for SINUMERIK 840D".
The user program can only read these system variables.
System variables The external control signals can be evaluated double-word-serial in the NCK-
$A_INSED[1,2] SPL via these system variables:
$A_INSED[1] corresponds to $A_INSE[1...32]
$A_INSED[2] corresponds to $A_INSE[33...64]
The user program can only read these system variables.
System variables Up to 64 external status signals can be addressed by the NCK-SPL via these
$A_OUTSE[1...64] system variables. The status of eight system variables can be copied to an
NCK I/O output module via MD $MN_SAFE_OUT_HW_ASSIGN[0...7].
$MN_SAFE_OUT_HW_ASSIGN[0] <- $A_OUTSE[1...8]
$MN_SAFE_OUT_HW_ASSIGN[1] <- $A_OUTSE[9...16]
$MN_SAFE_OUT_HW_ASSIGN[2] <- $A_OUTSE[17..24]
$MN_SAFE_OUT_HW_ASSIGN[3] <- $A_OUTSE[25..32]
$MN_SAFE_OUT_HW_ASSIGN[4] <- $A_OUTSE[33..40]
$MN_SAFE_OUT_HW_ASSIGN[5] <- $A_OUTSE[41..48]
$MN_SAFE_OUT_HW_ASSIGN[6] <- $A_OUTSE[49..56]
$MN_SAFE_OUT_HW_ASSIGN[7] <- $A_OUTSE[57..64]
For a precise description of MD parameterization refer to Chapter 4, "Machine
data for SINUMERIK 840D".
These system variables can be read and written by the user program.
