(I/O error code of JW model)
• When error numbers 98 through 9C
(H)
occur, the module will store “rack No.” and “slot No.” in the
parameter address 005000
(8)
in the JW-20RS.
When more than one module has and error, the lowest “rack No.” and “slot No.” will be stored.
•A special I/O module error (9B
(H)
) can be detected by the JW-2DA/8AD/11DU/12DU/12PM. When
the JW-2DA/12PM detects this error, you can also assume that there is a problem in the 24 V
power supply.
•A fuse blown error (9C
(H)
) can be detected by JW-12S/13S/32S/33S/35S.
If the error cannot be eliminated after replacing the module in which the error occurred, check the
modules in the JW-20RS and then in the rack panel.
