The first record to be read. The first record number can be specified in the
range between 0000 and 003F (0 to 63 decimal) where 0000 is the oldest
record.
The number of records to read is specified between 0001 and 0040 (1 to 64
decimal) in the command. The response returns the actual number of records
read.
The maximum number of records that can be stored in the error log. Care is
required as the error log differs according to the type of PLC or CPU Bus Unit.
In an FL-net Unit, the maximum number of stored records is fixed at 40 (64
decimal).
The number of records stored at the time the command is executed is
returned.
The specified number of error log records from the beginning record number
is returned sequentially. The total number of bytes in the error log is calculated
as the number of records x 10 bytes/record. Each error log record thus com-
prises 10 bytes, configured as follows:
