Sharp JW-20CM, JW-20RS (3) Error code

(3) Error code

When an error occurs in the JW-20CM, it stores the occurred error’s code to system memory #170 of each station’s PC.

	Error	Cause	Error code stored to system memory					Measure
	code
	(HEX)		#160		#170
	01	ROM error, upper CPU
	02	RAM error, upper CPU
							Replace the JW-20CM
	03	2 port RAM error against PC, upper CPU
	04	2 port RAM error against		53(H)
		communication CPU, upper CPU
								• Check the communication
	11	ROM error, communication CPU
								cable
	12	RAM error, communication CPU
								• Check for doubled allocation
	18	Communication LSI error, communication CPU
								of slave station number
	1F	No response				1F (H)		• Replace the JW-20CM
	20	More than one token detected				20 (H)	Check the parameter setting
	21	Doubled address detected				21 (H)	and switch
	22	Fault of sending section				22 (H)	Replace the JW-20CM
	23	Token does not return within the rated interval				23 (H)
							Check the communication cable
	2A	Overflow of receiving buffer.				2A (H)
		Occurs when the upper CPU processing is delayed.
	2B	Flame length error				2B (H)	Check the communication cable
							Replace the JW-20CM
	2C	Media error				2C (H)
	30	EEPROM error				30 (H)	Replace the JW-20CM

	BE	BCC error				BE (H)	Check the switch setting
	BF	Parameter setting error				BF (H)
	C1	Communication error				C1 (H)	Check the communication
	to	• After converting into octal, the lower two digits				to

		error. (Ex. C1(H) = 301(8)= slave station 01)

•In some cases, error code 23(H) or 2A(H) is stored when inputting power. This is not an error.
