Writing to the EEPROM of the JW-22CM, start operation [HEX (hexadecimal), byte]

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).”

Remarks

·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. To recover from this condition.

Treatment when error code 6F(H) appears and COMM is turned OFF.

 

 

 

Check number of top addresses/bytes of master station “relay link” and “register link.”

 

 

 

 

Check the set value for number of connected stations.

 

 

 

 

 

 

Check the set value for master station flag top address.

 

 

 

 

 

 

Check whether the function is set to “relay register link.”

 

 

 

· Written contents into the EEPROM are automatically written to the RAM of the JW-22CM

 

 

 

when turning ON the power of the PC. At reading, 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).
