(4) Error history

When the JW-21MN has errors, it stores them in an error history register. The storage area is
specified using the module No. switch setting value.

The storage area for the error history (128 bytes) is divided into 8 sections (16 bytes each). The
JW-21MN stores up to 8 errors, in the order they occurred. If a ninth error occurs, the oldest error
data will be deleted.

Details of the data for each error (16 bytes) are as follows.

*1: When the JW30H is used,

system memory should be set
to #210 = 002

(8)

.

*2: Setting the module No. switch

to "5" or "6" is only valid when
the model switch on the JW-
21MN is set to "2."

*3: The register address on the left is correct when the

JW20H is used and the Module No. switch is set to
"1."

used for the control module of a

JW20/20H/30H, ignore data from bytes 1

(Since the JW-21CU/31CUH/31CUH1 do
not have a clock function, they cannot

store this data correctly.)
