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 tim e 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

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.

Input register (30001-39999)
Data Address Description
Mapping area 31001-39000 Setting the address of input
resister of GC1000MkII/ASIU.
ASGW reads the addressed
data on GC1000MkII/ASIU.
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 ASGW until turning off.
Retry to writing
When a write error of writing on coil or holding resistor of analyzer occurs,
ASGW tries to write on analyzes setted times. The number of retry times can be specified on the
setting file.
Time-out of communication
Value of time-out for communication between DCS and Modbus RTU can be set according to
communication speed. The value of mean time of each characters is set on the setting file.

4. Engineering
ASGW requires the engineering at installation, modification and address mappin g.
4.1. Installation
This section explains the setup of ASGW, license registration, IEC application loading and initializing of IP
address.
4.1.1. Preparation
Installation of the engineering tool
Install the resource configurator software including CD-ROM (NT203AJ-PC11E) to PC.
Resource configurater software is an engineering tool for STARDOM FCN/FCJ.
Installation of the ASGW software
Set the ASGW application software CD on PC.
Uncompress the following compressed file on PC.
(CDR)/ASGW/INSTALL_ASGW.ZIP
Confirm the following folder is created.
([Uncompressed folder]/INSTALL_ASGW
4.1.2. Initial setting
Loading the license file
Download the ASGW license file from the STARDOM license publishing web site.
Setting the system card
Set the system compact flash card combined with FCJ on PC.
Click the following batch file.
([Uncompressed folder]/INSTALL_ASGW/install_ASGW.bat
This batch file sets the IEC application, Java application and system setting file on the system card.
System setting file includes initial IP address setting.
The initial IP address can be changed later.
After writing, the system card set on the CPU card of ASGW, and turn on the ASGW.
Initial IP address = 192.168.1.151
NOTE:
Do not format the system compact flash card. The card becomes invalid and new one is required.
Initializing with resource configurator
The mothod of initial setting operation with resource configurator is described on the instruction manual.
The work flow is described in this chapter. However, refer to the instruction manual for details of each
operation.
1) Setting the IP address
Refer to 5.1 Modification of IP address.
5-3 IM 12Y04D01-01
2) Loading the license file
Download the license file that is loaded from the STARDOM web site to ASGW with the resource
configurator.
Refer to online help of resource configurator
3) To enable Java.
4) Setting the network
Ethenet of ASGW has dual or single type and dual type has duplex and separated mode.
Select the type and mode for the system.
Reboot the ASGW. After starting ASGW confirm that the IP address is correct by ping command of PC.
5) Setting th serial port
In the case of Modbus RTU, the communication parameters should be adjusted to a connected device.
Refer to 5.2.
4. Engineering
IM 12Y04D01-01 5-2
4.2. Data mapping
Mapped address is setted with one file named “ASGW_MAP.CSV”.
Mapping operation is complete when the file is transfered to ASGW with FTP and the ASGW is rebooted.
ASGW checks the file at startup. Information of error diagnosis is confirmed with Web browser.
At the installation on ASGW a sample file is setted. Mapping operation is realized with modification of the
sample file.
The mapping file does not depend on ASGW, so that the composition of mapped file is available in advance
without ASGW.
*
Example of mapping file
4.3. Loading a mapping file
After the installation of ASGW, turn on the power and connect the ASGW to PC with Ethernet cable.
Open the web browser on PC and input the address of ASGW as http://(IP
address of ASGW).
When the homepage of ASGW is displayed, click the “Mapping File”.
FTP windows appears and account and password are required.
Enter the following characters.
Account: “stardom”
Password: “YOKOGAWA”
Mapping file “ASGW_MAP.CSV” is displayed on FTP window.
Move this file to PC.

4.4. Setting
This file consists of text characters. Editing can be done with “Notepad” software, but “MS-Excel” software
is recommended. The edited file should be saved with “CSV” as an extension.
Each line has meaning in the map file. A line beginning with character # is interpreted as a meaningful line.
And a comment line does not begin with character “# “.
#SLAVE, n
This n is the Slave ID when DCS accesses to ASGW with Modbus interface.
#RETRY, m
This m is the number of retry times when a write error occurs.
#TOUT, t
This t is time-out value of characters in the communication between DCS and Modbus RTU. Adjust the
value depending on communication speed. Unit is ms [millisecond] and range is 10 to 5000.
Definition of GC1000MkII/ASIU
This is the setting of analyzer ID. The number of analyzer units that is connected to one ASGW is 31 sets
Every analyzer should be defined by unique StnID number. This StnID is key data on Modbus interface.
#STN Key word
StnID ID number of analyzer (1-254)
StnType Type of analyzer “GC1000” or “ASIU”
IP_Address IP address of GC1000MkII/ASIU
Example “#STN, GC1000,3,192.168.0.1”
Definition of Mapping
This is setting of Modbus address
Refer to the Modbus address tables (Table 3.3-7) for available mapping conditions.
#MAP Key word
StnID ID number of analyzer (defined in #STN)
ASGW_Address Modbus address of ASGW
Target_Address Modbus address of target analyzer
Example: “#MAP,3,11001,10001”
The order of line is not restricted, and blank line is ignored.

4.5. Transfer to ASGW
Open the FTP window on PC that is shown in 5.3.1
Move the modified mapping file to FTP window.
Restart ASGW after over writing is complete.
4.6. Diagnosis information
After re-starting the ASGW, Open the web browser.
When “Mapping Error” is clicked, the diagnosis information window appears.
The contents are as follows.
a) Out of range addressing
b) Duplicated addressing
c) Invalid combination of mapping
