Description:
Due to the obsolescence of a Flash PROM (Manufacturer: AMD) on the three modules81EU50R1210, 83SR50R1210 and 83SR51R1210 the replacement component (Manufacturer:
Macronix) was implemented in October 2018.
In one project which was delivered with modules using the new Flash it was discovered that
there are problems with writing/reading application programs with PDDS.
Modules are loaded via the PDDS with application programs. These are first written to the
RAM. Subsequently, the processing program of the modules copy the application programs
from the RAM into the Flash. For the PDDS, however, the process is complete after successfully writing to the RAM and therefore PDDS is not reporting any error.
Copying from RAM to Flash does not or only partly take place. If you try to read back the application program with PDDS it is queried from the Flash. Since there are no data or incorrect
data, the error message appears "Disable, list code not found".
When pulling and plugging a module, the application program stored in RAM is deleted because the memory is volatile.
The following steps are necessary to identify if modules are affected:
1. Identify the production date of the modules. This can be done by checking the label on the
package or the connector. Or it can be done using GAF/OVE functionality of PDDS.
The label is e.g. printed with the following information:
Ident number Module Designation HW-Index Date code + Serial number
GJR2403800R1210 81EU50R1210 HW-Index: B K1118 0050
