'IEC program not available' message could get returned when viewing an NOE web page using a ProWORX 32



Goals and Symptoms

Viewing the 'Diagnostic' web page of a Quantum 'NOE 771 xxx' module could return the error message
'IEC program not available'.

Facts and Changes

Attempts to view the diagnostic web page of a Quantum '140 NOE 771 xx' module whose PLC configuration was
configured using ProWORX 32, could return the error message 'IEC program not available' if the NOE is configured with
a executive firmware version 3.3 or lower.

Causes and Fixes

This is due to the Quantum PLC having been previously configured with a Concept 'IEC' application or a Concept
984 application that had the IEC option checked off in the plc configuration..

To resolve this problem, download a Concept configuration (make sure that the 'IEC' option is deselected) to the
PLC and then re-download the ProWORX 32 project.
