information. This area is shared with source code memory, being the total area the sum of “program
memory” and “source code memory”.
User files memory: This memory area offers another way for the user to store files such as doc, pdf,
images, and other files. This function allows data recording as in a memory card. For further
information check User Files MemoryUser Files Memory.
Maximum number of tasks: The maximum number of tasks defined for each CPU model, and
among different project profiles, is better detailed in the chapter Maximum Number of Tasks.
Redundancy support (half-clusters): The software version 1.1.0.0 or onwards/product revision AB
or onwards supports redundancy of NX3030 CPUs.
Event oriented data reporting (SOE): The data types are found in the DNP3 Device Profile.
Maximum number of PROFIBUS-DP network: From MasterTool IEC XE version 1.22 and
onwards, 4 PROFIBUS-DP networks are supported for NX3020 and NX3030 CPUs. Previous
versions support 2 PROFIBUS-DP networks. The limit of PROFIBUS-DP masters is 4, which means
that only 2 redundant networks can be used.
