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.

Parameter address D7 D6 D5 D4 D3 D2 D1 D0

005000(8)

Rack No.

Slot No.

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.
