· Calculate BCC of parameter addresses 000000 to 003775
When normal, the remote I/O will start operation.

When abnormal, the module will output error code BE
① Check the parameter contents
When normal, the module calculates BCC and writes the check sum
value into address 003776
When abnormal, it outputs a BF
② Changes the value to 00

If a write error to the EEPROM occurs, it outputs a 30
keeps the value set to 80
