ABB 83SR50 GJR2395500R1210 Control Module

Due to the obsolescence of a Flash PROM (Manufacturer: AMD) on the three modules 81EU50R1210, 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.

 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.
