A-2 List of System-defined Variables

This section describes the system-defined variables that are unique to the AI Controllers.
System-defined variables except for the AI Controller are used in the same series. For more informa-
tion on the NX-series Controllers, refer to the NJ/NX-series CPU Unit Software User's Manual (Cat.
No. W501). For more information on the NY-series Controllers, refer to the NY-series Industrial Panel
PC / Industrial Box PC Software User's Manual (Cat. No. W558).

Common Variables

Variable name
_AIC_Version
_Card1Capacity
A-6
Meaning
Shows the version of the AI Con-
troller package.
The integer part of the version is
stored in the element number 0.
The fractional part of the version
AIC Version is stored in the element number
1.
Example) If the unit version is
1.10, 1 is stored in element num-
ber 0 and 10 is stored in element
number 1.
Specifies the total capacity of the
inserted SD Memory Card (NX-
series) or that of the Virtual SD
Memory Card (NY-series).
The unit is MiB. (1 MiB =
1,048,576 Byte)
The value is updated every 60
SD Memory Card Stor-
seconds.
age Capacity
If the SD PWR indicator is not lit,
such as when an SD Memory
Card is not inserted, the value is
"0" (NX-series).
If the Virtual SD Memory Card is
disabled, the value is "0" (NY-
series).
