S5-95F Error Diagnosis and Elimination
Error Blocks
Beginning in data word DW 64, a detailed report, including the cause of error, auxiliary information
such as the I/O address or count, and the time stamp is entered for each error that occurs. Each
such error report reserves 8 data words, and is sometimes referred to in the following as error
block. The error blocks begin with data word n (n = 64, 72, 80, 88, ..., 184).
To facilitate understanding, the error block is subdivided into bytes which are numbered from 0 to
15.
