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(H)				Measure
code
(HEX)		#160	#170 to 177
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

1F	No response			1F		• Replace the JW-20CM
20	More than one token detected		20		Check the parameter setting
21	Doubled address detected		21
22	Fault of sending section		22		Replace the JW-20CM
23	Token does not return within the rated interval		23		Check the communication cable
2A	Over flow of receiving buffer.			2A	Check the

6E	BCC error			6E	Check the parameter setting
6F	Parameter setting error			6F

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

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

Remarks

•The error code stored in the system memory #170 is shifted to #170 to #177 one after the other as new errors occur. Thus, the system memory can store up to 8 errors. When the PC is operating by RAM, these error codes do not disappear even after turning OFF the power.

The contents of system memory #170 to #177 are kept storing after the JW-20CM recovers from the error.
