Writing to the EEPROM of the JW-20CM, start operation [HEX (hexadecimal), byte]

·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).”

Setting	Contents
value (H)
0 0(H)	Stop operation of the remote I/O (initial value)

·Calculate BCC of parameter addresses 000000 to 003775(8).

0 1 When normal, the remote I/O will start operation.

When abnormal, the module will output error code BE(H).

①Check 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.

8 0(H) 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(H).

8 1(H) ② Changes the value to 01(H) (starts the operation of the remote I/O), and

writes it into the EEPROM.8 If a write error to the EEPROM occurs, it outputs a 30(H) error code and

keeps the value set to 81(H).
