Anybus M-Bus to Modbus-TCP Gateway User Manual Doc: HMSI-27-300, Rev: 1.10
7.4 Configuration files
The A:/ directory of the gateway contains configuration files for the system and for the connected me-
ters. The configuration files are updated when changes are made via the web interface, but can also be
edited manually. Some parameters can only be changed by editing the configuration files manually.
7.4.1 System configuration file
The file A:/chip.ini is the main system configuration file which contains general system parameters. The
parameters are arranged in two groups. Parameters that are not explicitly configured in chip.ini are set
to their default values.
Manual changes to the configuration file will take effect after the gateway has been rebooted.
When editing configuration files you must use an UTF-8 capable text editor, such
as Notepad++
. Since the configuration files do not contain a byte order mark
(BOM), your editor may need to be manually set to use UTF-8 encoding.
The configuration files should only be edited by trained personnel as there
is a risk of restricting functionality of the gateway.
