Coil (00001 to 09999)
Data Address Description
DO ON com-
mand
00101 to 00116 A 1 is set when DO001 to DO016 is ON. The coil is back to 0 auto-
matically after setting a 1.
DO OFF com-
mand
00201 to 00216 A 1 is set when DO001 to DO016 is OFF. The coil is back to 0 auto-
matically after setting a 1.
Input relay (10001 to 19999)
Data Address Description
ASIU normal 10001 Neither Power Failure, I/O module error nor IOP status happens. All
of the address from 12001 to 12199 has 0 values.
ASIU error 10002 Either Power Failure, I/O module error or IOP status happens. One of
the addresses from 12001 to 12199 has 1 value.
DI (Digital
Input) read
10301 to 10316 DI01 to DI16
DO (Digital
Output) read
10401 to 10416 DO16 to DO16
Power Failure 12001
12002
A 1 is displayed when Main Power is failed.
A 1 is displayed when 24 V DC Power is failed.
I/O module
error
12011 to 12014 A 1 is displayed when the module is failed. The address is followed
the location of the I/O module. From left to right, 11, 12, 13 and 14 is
applied.
AI IOP status 12101 to 12116 It corresponds to AI01 to AI16. A 1 is displayed when it is IOP status.
Input register (30001 to 39999)
Data Address Description
AI read (Real
data)
30401 to 30432 The average value during 1 second with 10 scans times. However
when it is IOP status, IOP value, which is 0 or 1, is displayed. When
real number format is selected, the data is displayed with 2 words
address.
The data range is 0.0 to 1.0
AI read (9999) 30501 to 30516 The average value during 1 second with 10 scans times. However
when it is IOP status, IOP value, which is 0 or 9999, is displayed. It
means data normalized by 9999 (Scaling Coefficient).
The data range is 0 to 9999
AI read (65535) 30601 to 30616 The average value during 1 second with 10 scans times. However
when it is IOP status, IOP value, which is 0 or 65535, is displayed. It
means data normalized by 65535 (Scaling Coefficient).
The data range is 0 to 65535
Holding register (40001 to 49999)
Data Address Description
Not used
l Access to the address not listed or mapped
Access to the address that is not shown on the table or not mapped does not generate an error.
However, the value of data is uncertain.
DCS can write on coil or holding register of ASGW that is not defined, however ASGW does not
write it on analyzers and the written data is kept on ASIU until turning off.
