Correct the Input/Output length validation.

1/ Correct the validation - should be as stated in EtherCAT Slave Protocol API V4.5.0, p. 46, table 19 (screenshot attached "EtherCAT API.png").

2/ Fix the error message. Should be "Total sum of input and output bytes cannot exceed 512 bytes." or "Total sum of input and output bytes cannot exceed 1024 bytes".
