declared identification number.
FALSE – There are no racks with a
non-declared identification number.
TRUE – There are some duplicated
slot address.
TRUE – There are no duplicated slot
address.
Table 7-6. CPU Summarized Diagnostics Table
Notes:
Direct Representation Variable: "n" represents the value set in the CPU through the MasterTool
IEC XE software, such as initial address diagnostics.
AT Directive: In the description of the symbolic variables which use the AT directive to make the
mapping in direct addressing variables, the syntax that must be put before the desired summarized
diagnostic is DG_Module.tSummarized, when the Module word is replaced by the used CPU. E.g.
for the incompatible configuration diagnostic it must be used the variable:
DG_NX3010.tSummarized.bConfigMismatch. The AT directive is a word reserved in the
programming software, used only for diagnostic indication.
Configuration Mismatch: The incompatible configuration diagnostic is generated if one or more
modules of the rack does not correspond to the declared one, so, in the absence or different modules
conditions. The modules inserted in the bus that were not declared in the project are not considered.
Swapped Modules: If only two modules are changed between themselves in the bus, then changed
diagnostic can be identified. Otherwise, the problem is treated as “Incompatible Configuration”.
Modules with Fatal Error: In case the modules with fatal error diagnostic is true, it must be verified
which is the problematic module in the bus and send it to Altus Technical Assistance, as it has
hardware failure.
Module with Parameterization Error: In case the parameterization error diagnostic is true, it must
be verified the module in the bus are correctly configured and if the firmware and MasterTool IEC
XE software version are correct. If the problem occurred when inserting a module on the bus, make
sure the module supports hot swapping.
Bus Error: Considered a fatal error, interrupting the access to the modules in the bus. In case the bus
error diagnostic is true, an abnormal situation due to the hot exchange configuration selected might
have occurred or a hardware problem in the bus communication lines, then, contact Altus Technical
Assistance.
Hardware Failure: In case the Hardware Failure diagnostic is true, the CPU must be sent to Altus
Technical Assistance, as it has problems in the RTC, auxiliary processor, or other hardware
resources.
Software Exception: In case the software exception diagnostic is true, the user must verify his
application to guarantee it is not accessing the memory wrongly. If the problem remains, the Altus
Technical Support sector must be consulted. The software exception codes are described next in the
CPU detailed diagnostics table.
Error in Memory Card: Memory Card diagnostics are only available for the NX3010, NX3020 and
NX3030 CPUs. Diagnostic Message: The diagnostics messages can be visualized by the CPU
graphic display using the OTD key or using the WEB, through the CPU diagnostics page.
Serial Interfaces: COM 2 interface diagnostics are only available for the NX3010, NX3020 and
NX3030 CPUs.
