4.2 Data mapping
4.2.1 Preparation
The IP addresses of analyzers, and mapping data of the Modbus address of analyzers onto the
address of ASGW, are defined in the ASGW_MAP.CSV file.
Mapping operation is complete when the file is transferred to ASGW with FTP and the ASGW is
rebooted.
ASGW checks the file at start-up. Information of error diagnosis is confirmed with Web browser.
At the installation on ASGW a sample file is setted. Mapping operation is realized with modifica-
tion 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.
