Hi Bytes 1&2 : 2521 : event id (byte1:event class and identifier; Byte 2 : error code)--->2: synchronous error, 5: imcoming interal error, 21: BCD conversion error. Byte 3 : 01 : priority class of the ob where error occured. Byte 4 : 79 : OB number (ob121) Byte 5 : 8c : type of block where occured(8c means fc) Byte 6 : 74 : reserved ? Bytes 7&8 : 0000 :source of error (accumulator 1) Bytes 9&10 : 0022 : number of block where error occured Bytes 11&12 : 0532: relative address of command which error occured.
