1. Outline 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.
This chapter explains the configuration of the hardware and software of STARDOM FCJ required for ASGW. Refer to the General Specifications of STARDOM for detais of each item. 2.1. Hardware configuration The following type FCJ is required for the ASGW. Model Name Item Remarks NFJT100-S0x Note: x is the G3 option.
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...

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.

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 00nnn Time is set for selected GC1000MkII.

The data are kept after writing on GC1000MkII. Mapping area 41001-49000 Setting the address of input register or holding register of GC1000MkII/ASIU. ASGW only reads the input register GC1000MkII/ASIU. ASGW only writes the holding registor on GC1000MkII. Available register GC1000MkII...

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.
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.

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.
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.
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.
Out of range addressing b) Duplicated addressing c) Invalid combination of mapping Modify the setting file according to the error that is shown in this window. If the file includes errors, ASGW ignores the error occurred line on the file. IM 12Y04D01-01...

5.2 Modification of serial port setting In the case of using the Modbus RTU as external interface of ASIU/ASGW this operation is required. ASIU has one and ASGW has two communication ports and all initial setting data are as follows.
