Remarks
- The error code stored in the system memory #170 shifts from #170 to #177 one by one each new
error code occurrence, and stores the error conditions up to 8 causes. When the JW30H is in
RAM operation, the error code memory does not disappear even if the power to the JW30H is
turned off. The system memory #170 to 177 keeps its contents after recovering from the error
condition.
- When the JW-32CUM1 (general purpose communication section) becomes error, it stores error
code "53" (option error) in the system memory #160.
- In the case of an option error "53
(H)
," when you monitor system memory #050, the bit (module No.
swith setting value) of error option module switches ON. When more than 1 bit is error, these bits
switch ON. The each ON bit becomes OFF by recovering from the error condition. But the last ON
bit does not become OFF even if the error condition recovers.
