Ethernet Interfaces: The diagnostics regarding to the NET 2 interface are only available for the
NX3020 and NX3030 CPUs.
Detailed Diagnostics
The tables below contain Nexto Series’ CPUs detailed diagnostics. It is important to have in mind the
observations below before consulting them:
 Visualization of the Diagnostics Structures: The Diagnostics Structures added to the Project can
be seen at the item “Library manager” of MasterTool IEC XE tree view. There, it is possible to
see all datatypes defined in the structure
 Counters: All CPU diagnostics counters return to zero when their limit value is exceeded
 Direct representation variable: “n” represents the value configured at the CPU through
MasterTool IEC XE as the initial diagnostics address
 AT Directive: At the description of symbolic variables that use the AT directive to map it in
direct mapping variables, the syntax to be used before the desired summarized diagnostic is
DG_Module.tSummarized., where the word Module must be replaced by the CPU being used.
For example, for the Configuration Mismatch diagnostic, use
DG_NX3010.tSummarized.bConfigMismatch. The AT directive is a reserved word of the
programmer, and some symbolic variables that use this directive indicate diagnostics.
