1. Outline
ASGW is a component designed for Ethernet analyzer bus system. It is realized with the gateway software on
FCJ hardware. This system concentrates the Modbus accessed between multiple analyzers and DCS.
This system provides efficient engineering and communication performance.
ASGW has two type interfaces: Modbus TCP Ethernet one port and Mobus RTU serial.
Modbus mapping is realized with address table and programming is not necessary.
FCJ is described as ASGW is in this document.

3. Functions
IM 11B06E01-01 3-1
3. Functions
ASGW has the following functions
1. Interface to DCS through Modbus RTU Slave
2. Read and write data for multi-analyzers (GC1000MkII, Analyzer Interface Unit)
3. Mapping of the data between GC1000MkII/Analyzer Interface Unit and ASGW Modbus
4. Alarm information
3.1. Interface for DCS
ASGW has Modbus RTU slave (two serial ports) function as interface to DCS.
Modbus RTU uses two RS232C communication ports. Both ports have the same functions. Two
communication ports can be used at the same time. When two masters request the same address, the last
accepted request is excuted according to update time of ASGW.
3.2. Address mapping
ASGW assembles the data of multiple analyzers, and offers the mapping table to DCS.
Maximum units of GC1000MkII : 31 sets
Function Available address for
mapping Available points GC1000 address area
Coil 01001-09000 8000 Coil, Input relay
Input relay 11001-19000 8000 Input relay
Holding
register 41001-49000 8000 Input register,
Holding register
Input register 31001-39000 8000 Input register
When the address of GC1000MkII/ASIU is coil or holding register, writing on the specific address is
available
Refer to the Modbus interface table in section 3.4
3.3. Alarm information
Alarm conditions of communication with analyzers are mapped as input relay.
In operation:
It shows that ASGW accesses to analyzers specified on the mapping file.
Communication failure:
It shows that a time-out error occurs on communication with analyzers. Network line or analyzer failure
may cause the error.
Write failure:
It shows that a write error occurs on analyzer. The failure is reset when the next writing is normal.
3.4. Modbus interface table
ASGW has the function of Modbus RTU Slave.

Vender : “YOKOGAWA”
Product: ”ASIU”
REVISION: “1.01.01” (example)
Update rate:
Accesses to GC1000 /ASIU every 100ms. ASGW supports each read and write requests sequentially.
Read and write is individually performed, so that it is possible to offer one read request and one write
request at the same time.
3. Functions
IM 11B06E01-01 3-3
Coil (00001-09999)
Data Address Description
Time setting request 00001 For all analyzers connected to ASGW
Time data should be set at the holding registers
40001- 40004 before request.
Value turns to “0” after writing.
Setting for ASIU is invalid.
Individual time setting
request 00nnn Time is set for selected GC1000MkII.
“nnn” is 100 + StnID
“nnn” (=101 - 354)
The setting for ASIU is invalid.
Value turns to “0” after writing.
Mapping area 01001-09000
Setting the address of coil and input relay of
GC1000MkII/ASIU.
ASGW only reads the input relay on
GC1000MkII/ASIU
ASGW only writes the coil on
GC1000MkII/ASIU
Available is the following coils
GC1000MkII
00001: Run command
00002: Stop command
