Writing to the EEPROM of the JW-20CM, start operation
[HEX (hexadecimal), byte]
From the previous page
· Write “81
(H)
” into parameter address 003777
(8)
and write the set parameter contents into the
EEPROM of the JW-20CM. Then start the remote I/O operate.
· After starting operation, the setting value changes to “01
(H)
.”

.
When normal, the remote I/O will start operation.
When abnormal, the module will output error code BE
(H)
.
①
Check the parameter contents
When normal, the module calculates BCC and writes the check sum
value into address 003776
(8)
.
When abnormal, it outputs a BF
(H)
error code.
②
Changes the value to 00
(H)
(stops the operation of the remote I/O), and
writes it into the EEPROM.
If a write error to the EEPROM occurs, it outputs a 30
(H)
error code and
keeps the value set to 80
