Error memory by DCP modules in version 3.x - CN 37-064 EN
- The error memory is implemented on DCP modules up to hardware revision >= 4.018 and EPROM version >= 3.19.
To avoid the error all force parameters, which have to be active after a redundancy toggle, should be written with the 'correct' value.
The problem is fixed in SW version 3.2 with Service Pack V32TOL_1.
At the version V3.1, an error memory has been implementedin DCP02 and DCP10. If sporadics fatals faults has been detected during the hardware testof the CPU, the boot-processing of the CPU will be stopped and an error message appears onthe diagnostic interface:
Error code 0x26000001 added to error memory ...
P r o g r a m t e r m i n a t e d ! ! !
During next self test, a former detected error will bedocumented in the form:
In former operation, following self testerrors have been occured:
970818;132528;0x26000001;test of SRAM, word access 8 times skipped
970926;082011;0x22002007;test of primary LAN: serial interface 1 times skipped
The DCP module awaits an acknowledgment (
The string '8 times skipped' is a hint which means that this messge was passed 8times, in order to continue operation.
The error memory stores up to 5 independent entries. After the 5 th entry has beenwritten, the DCPxx module rejects the further program execution. The following messagewill appear on the dignostic interface:
The maximum error count has been reached :further operation will be rejected.
