6. Configuring the Gateway
Importing/exporting a Modbus slave configuration:
AbcConf offers the possibility of independently saving and loading the configuration of a node on the
downstream “Sub-Network”. For instance, this will allow you to build a library of Modbus slave templates, so that
you can use them in any configuration.
To save the configuration of a Modbus slave, select the node it corresponds to, then choose “Save Node” from
the menu whose name corresponds to the name of the selected node. A dialog box will then appear asking you
to save the configuration (export in XML format).
To insert a node using the XML file containing a Modbus slave configuration as a template, use one of the two
methods shown below:
a) Select “Sub-Network”, then choose “Load Node” from the “S
ub-Network” menu. A dialog box asks you to
choose a file containing a Modbus slave configuration (import in XML format). A new node is added after all
the other configured nodes. Its name and its whole configuration are identical to those of the Modbus slave,
as it was configured when it was saved.
b) Select one of the “Sub-Network” nodes, then choose “Insert from File” from the menu whose name
corresponds to the name of the selected node. A new node is added just before the selected node. Its name
and its whole configuration are identical to those of the Modbus slave, as it was configured when it was
saved.
You will then change (1) the name of the node, (2) the address of the corresponding Modbus slave and (3) the
location of the data exchanged between the gateway’s memory and this Modbus slave. All of these operations
are described in chapter 6.10 Changing a Modbus Slave Configuration, page 67, and in chapter 6.11 Adding and
Setting Up a Modbus Command, page 68.
