Table 2-5. Specific Features
Notes:
Addressable input variables memory (%I): Area where the addressable input variables are stored.
Addressable variables means that the variables can be accessed directly using the desired address.
For instance: %IB0, %IW100. Addressable input variables can be used for mapping digital or analog
input points. As reference, 8 digital inputs can be represented per byte and one analog input point can
be represented per two bytes.
Total addressable output variables memory (%Q): Area where the addressable output variables
are stored. Addressable variables means that the variables can be accessed directly using the desired
address. For instance: %QB0, %QW100. Addressable output variables can be used for mapping
digital or analog output points. As reference, 8 digital outputs can be represented per byte and one
analog output point can be represented per two bytes.
The addressable output variables can be configured as retain, persistent or redundant variables, but
the total size is not modified due to configuration.
The Nexto Series NX3030 CPU allows defining an area of redundant variables inserted inside of the
addressable output variables %Q. The subset of addressable output variables memories are part of the
total size of available memory.
Addressable variables memory (%M): Area where the addressable marker variables are stored.
Addressable variables means that the variables can be accessed directly using the desired address.
For instance: %MB0, %MW100.
Symbolic variables memory: Area where the symbolic variables are stored. Symbolic variables are
IEC variables created in POUs and GVLs during application development, not addressed directly in
memory. Symbolic variables can be defined as retain or persistent. In these cases, it will be used the
memory area of retain symbolic variables memory or persistent symbolic variables memory
respectively.
Persistent and Retain symbolic variables memory: Area where are allocated the retentive
symbolic variables. The retentive data keep its respective values even after a CPU’s cycle of power
down and power up. The persistent data keep its respective values even after the download of a new
application in the CPU.
ATTENTION:
The declaration and use of symbolic persistent variables should be performed exclusively through
the Persistent Vars object, which may be included in the project through the tree view in Application
-> Add Object -> Persistent Variables. It should not be used to VAR PERSISTENT expression in
the declaration of field variables of POUs.
