CJ-series EtherCAT Slave Units Operation Manual (W541)
Specify the first record to be read. The first record number can be specified in the range
between 0000 and 00F9 hex (0 to 249 decimal). The 0000 hex record is the oldest
record.
The number of records to read is specified between 0001 and 0063 hex (1 to 99 deci-
mal).
Indicates the maximum number of records that can be stored in the error log. The max-
imum number of error log records depends on the model of CPU Unit or CPU Bus Unit
being used. In an EtherCAT Slave Unit, the maximum number of stored records is fixed
at 00FA hex (250 decimal).
The number of records stored at the time the command is executed is returned.
The number of actual records read is returned as a hexadecimal value.
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 comprises 10 bytes. Refer to
Error Log Data Format on page A-31.
