Sharp JW-21MN manual 12-7, System memory #170 to 177 option module error code

(1)System memory #170 to 177 (option module error code)

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-21MN recovers from the error.

#177 #176 #175 #174 #173 #172 #171 #170

	6E Occurrence of BCC error

6E	Occurrence of parameter
	6F

(2)System memory #160 to 167 (self diagnosis error code)

When any of errors "01(H)" to "18(H)" occurs among the error codes listed on the previous page, the JW-21MN stores error code "53(H)" (optional error) in the system memory #160. It does not store any error code in system memory #170.

(3)System memory #150 (monitor error switch number)

When you monitor the system memory #050 at the occurrence of error code "53(H)," you can check the module No. switch setting value of the error causing option module with a bit pattern. (At normal: OFF, at error: ON)

7	6		5	4	3	2	1	0
#050
Module No. switch
		6	5	4	3	2	1	0
setting value

[Ex.] In the case below, an option module having the module No. switch setting value as "2" is an error.
