Write 81(H)
Writing to the EEPROM of the JW-20CM, start operation [HEX (hexadecimal), byte]
From the previous page
· Write “81
(H)
” into parameter address 007777
(8)
and write the set parameter contents into the EEPROM
of the JW-20CM. Then start the JW-20CM.
· After starting operation, the setting value changes to “01
(H)
.”

· Writing time to EEPROM is approximately 0.7 sec. When any error is found for parameter
settings, the JW-20CM lights the error code (6F
(H)
) by the indication lamp.
When error code 6F
(H)
lights,
Check flag top address
If the master station also lights up with error code 6F
(H)
, check the top address and
number of bytes in the relay link and register link in the master station which corresponds
to the slave station in which the error occurred.
· Written contents into the EEPROM are automatically transferred to the RAM of the JW-20CM
when turning ON the power of the PC. At transferring, the PC checks BCC and compares
BCC check code of the parameter memory address (007776
(8)
). When an error is found, the
JW-20CM lights the error code (6E
(H)
) by the indication lamp.
· If "parameter initialization" is selected, the module initializes parameter addresses 004000 to
007776
(8)
.
