easySoft/Galileo Application Note for Communicationfrom easySoft to Galileo
Introduction
easySoft is an intuitive, yet powerful software platform for Nano PLCs. easySoft
contains basic visualization features, however for systems that require advanced
graphics and visualization, Galileo should also be used in combination with easySoft.
The programmer will need to configure easySoft and Galileo to be able to communicate
with one another via Modbus TCP. The purpose of this application note provides
instructions on how to exchange data between the two software applications.

Configuring easySoft for Modbus TCP Communications
Once you have completed your easySoft program, you will need to ensure thatyou have set your device up to be a Modbus TCP slave. To do so, go to the Project
view, then click on the Modbus tab. You will then need to manually enable the Modbus
TCP server, and then select which marker and net words you want to allow to be usedin Galileo. If your tags are not in this range, Galileo will not be able to access them.
Additionally, if you want to be able to directly read physical I/O and clock data, the box
must be manually checked for this too as seen below in Figure 1.

Exporting Tags from easySoft
The next step is to export the program tags from easySoft as an itf file. This file
will contain the inputs, outputs, markers, and Real Time Clock data that are used in theproject. To create the file, click on the “itfExport…” button seen in Figure 1. It is
important to note that the “itfExport…” feature is only available in Version 7.11 andnewer of easySoft.

Create Modbus TCP Communication in Galileo
You will need to add a Modbus TCP communication connection in Galileo. This can bedone right away when creating a project by adding a Modbus TCP communication,otherwise the connection can be added after the project is created. To add
communications after creating a project, go to the Device tab in Galileo and then clickon PLC Communication. You then must select Modbus TCP and be sure to select thecorrect port on the interface column.

Figure 3
Once complete, the Modbus TCP connection you created will be added to the Tags tabof the project organization part of the application.

Import Tags into Galileo
Once the Modbus TCP connection is added and can be found in the Tags tab,
you can right click on it to import the itf you previously created.

Select the Communication connection you want the tags to import into, and then browse
for the file and click next.
