• When any of errors “01
(H)
” to “18
(H)
” occurs among the error codes listed on the previous page, the JW-
20CM stores error code “53
(H)
” (optional error) in the system memory #160. It does not store any error
code in system memory #170.
• In the case of an option error "53," when you monitor system memory #050, the bit 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.
• The option slot port numbers are assigned in the order 2, 3, 4, 5, 6, 7, and so on, starting from the
position closet to the control module.
