Time setting
request
00001
For all GC8000 or GC1000 MarkII connected to ASGW
Time data should be set at the holding registers 40001 to 40004 before
request.
Value turns to “0” after writing.
To set time to all analyzers or PCAS, #TSET must be specified as 255..
Individual time
setting request
00nnn
Time is set for selected GC8000 or GC1000 MarkII.
Time data should be set at the holding registers 40001 to 40004 before
request.
“nnn” is 100 + StnID *
“nnn” (= 101 to 354)
Value turns to “0” after writing.
The setting for ASIU is invalid.
Mapping area
01001 to 09000 Setting the coil or input relay address of analyzers.
ASGW only reads the input relay on analyzers and only writes the coil on
analyzers.
Available is the following coils

Input relay (10001 to 19999)
Data
Address
Description
In operation
10xxx
The value indicates “1” when the analyzer and PCAS is communicating.
“xxx” is StnID* of the analyzer.
“xxx” (=001 to 254)
Communication
error
10yyy
The value indicates “1” when there is an error in communication with ana-
lyzers and PCAS. Input relay or inout register needs to be defined.
“yyy” is 300 + Stn ID
“yyy” (= 301 to 554)
Write error
10zzz
The value indicates “1” when there is an error in writing data to analyzers
and PCAS; it returns to “0” when the next writing successfully finishes.
“zzz” is 600 + Stn ID
“zzz” (= 601 to 854)
Mapping area
11001 to 19000 Setting the input relay address of analyzers and PCAS.
ASGW reads the addressed data from analyzers and PCAS.
*:
