Parameters
Beginning Record Number (Command)
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.
Number of Records (Command, Response)
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.
Maximum Number of Stored Records (Response)
Indicates the maximum number of records that can be stored in the error log. The maximum number of error
log records depends on the model of CPU Unit or CPU Bus Unit being used. In an EtherNet/IP Unit or built-in
EtherNet/IP port, the maximum number of stored records is fixed at 40 (64 decimal).
Number of Stored Records (Response)
The number of records stored at the time the command is executed is returned.
Error Log Data (Response)
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, configured as follows:
398
