6F2S1931 (0.20)Centralized GRB200(Soft: 030, 031, 032, 033, 034)- 471 -9.2.4 Supervision of ECC on memory (ECC error)The error-correcting code memory (ECC memory), in the CPU module, is verified at any time.(i) Error levelThe error level has been set at level 1 (Serious error1) for the supervision; checking error onthe ECC is carried out at any time. If the error is detected, the IED restarts its operationautomatically. The supervision function runs on the CPU module1. Clearing the error messageis made promptly when the error is solved.1Note: The CPU module is discussed in ChapterTechnical description: Signal processingand communication module: Processing module.(ii) Error messageWhen detecting an error, an error message can be shown on the LCD screen and an LED is lit.Table 9.2-8 Error messages provided by the supervisor in CHK_ECCMessage and level Meaning of the informationCP*_ (ECC) errorError in the ECC is detected on the following module instructedwith “CP*_” as follows:CP1M: CPU moduleError level Serious error (Level 1)Table 9.2-9 Detailed information in Hexadecimal in CHK_ECCDisplayareaMeaning of the detailed informationLeft column Right columnToprow err_cnt value Error addressMiddlerow Number of detections of bit errors Address for rewriting failure occurred afterthe correction of single bit errorBottomrowNumber of rewriting failure occurredafter the correction of single bit errorECC status00000001: Completion of correction00000002: Failure of correction00000004: Detection of single error00000008: Detection of several errors00000010: Writing failure of data correction
