Parameters Beginning record No. (command): The first record to be read (the first
record number is 0000).
Max. No. of records (response): The maximum number of records that can
be recorded. (The maximum number of records is different for the CPU Unit
and the CPU Bus Units. CS-series SYSMAC LINK Units have 27 Hex (39)
records.)
No. of stored records (response): The number of records that have been
recorded.
No. of records (command and response): The number of records read.
Specify between 0000 to 0027 (0 to 39 records). If the number of records is

will be returned. If the number of records causes the response to exceed 540
bytes, records through 540 bytes will be returned along with a normal
response code.
Error log data (response): The specified error log records will be returned in
sequence starting from the beginning record number. The total number of
bytes required is calculated as follows:
