Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with Siemens S7-300/ET200S Ethernet. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
Supported Series: Siemens S7-300 Ethernet Series PLC, Ethernet module CP-343-1, CPU315-2 PN/DP, CPU317-2 PN/DP, CPU319-3 PN/DP, and ET200S.

How to Import Tag
SIEMENS STEP 7 program allows building files of user-defined tags (*.dif file and *.AWL file), and importing these files in EBPro (EasyBuilder Pro) via System Parameter Settings. The following describes how to build and import these two types of files.
Building a *.dif File
Create user-defined tags in Symbols
In the SIMATIC Manager, open the Symbols editor for your S7 program and create your user-defined tags with the appropriate addresses and data types.
Export the symbols as a DIF file
Click Symbol Table → Export to export the edited symbols. In the Export dialog, set the file type to *Data Interchange Format (.DIF), enter a file name (e.g.PLC_Tag.dif), and click Save**.
Building a *.AWL File
Create data blocks in Blocks
In the SIMATIC Manager, open the Blocks folder for your S7 program and create the required data block items.
Open Generate Source in LAD/STL/FBD
Open LAD/STL, FBD – Programming S7 Blocks from the Start menu, then click File → Generate Source.
Specify Sources as storage path
In the New dialog, select Sources as the storage path, enter a file name for the object (e.g.Object_Tag), then click OK.
Select objects to export
In the Generate source dialog, move the blocks you want to export from Blocks Not Selected to Blocks Selected, then click OK.
Export Source to build AWL file
Under Sources in the SIMATIC Manager, the saved file will appear. Right-click it and select Export Source to generate the*.AWLfile.
Import Tags in EBPro (EasyBuilder Pro)
The generated *.dif and *.AWL files can be imported in EBPro (EasyBuilder Pro) System Parameter Settings by clicking Import Tag.

When the import completes, a confirmation dialog will appear indicating that tag information was imported successfully.
Wiring Diagram
NOTE: Use a standard straight-through Ethernet cable to connect the HMI to the Siemens S7-300/ET200S PLC.
The diagram below shows the Ethernet cable wiring.
