Data link DL1 (master station) function

[3] Error code
While in the data link DL1 process, when master station (JW-32CUM1) has an error, the JW-32CUM1
stores its error code in the JW30H (JW-32CUM1) system memory #170.
- In case of switch setting error of slave station, the slave station PC stores error code in system memory
#170.
60 (H) Switch setting error
Error code Causes
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 PC is in RAM
operation, the error code memory does not disappear even if the power to the PC is turned off.
The contents of the system memory #170 to #177 keep in storage after recovering from the error
condition.
- When the JW-32CUM1 (general purpose communication section) becomes error, it stores error
code "53
(H)
" (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.
switch set value) of error option module ON. When more than one 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.
An error occurs on a remote I/O
slave station 1.
Data link DL1
switch setting error occurs.
