How to Import and Export Modbus Tags

1. Open your program in MapleLogic

2. Click the View tab and open the Variable Editor window.

3. In the Variable Editor window, click “More”, then “Export”.

4. This is where you would select the registers to export onto a .CSV file.

5. In the sample project, X, Y, and M bit registers are being used and D word registers is being used. Uncheck the registers you don’t want to export.

Note: EBPro will ONLY allow X, Y, M, or D bit or word registers to be imported as Modbus Tags.

6. Click export, name it, and save the .CSV file to your PC.

1. Here is the original format for the exported .CSV file from MapleLogic

2. Here is the format you’ll need to arrange the original CSV file into, in order for EBPro to recognize it.

Note: Not all columns need to be filled out to correctly import tags (only columns A, B, C, D, and F are required).

3. Now you can change the exported CSV file into the correct format

• Tag name (Variable) is moved into column A.
• Device Name is Modbus TCP/IP Master (device used in EBPro) and in Column B.
• Address and Type are divided into the C and D Columns.
  • For example: Pressure_Reading is exported as 400002 from MapleLogic but to import that modbus tag into EBPro, it needs to change to 4x_2 which is the same as 400002. 4x in Column C and 2 in Column D. Repeat for the other modbus tags.
• Column E can be left blank
• Column F is Undesignated. When the CSV file is imported, EBPro will automatically detect the type of tag (Bit, Word).

1. In your EBPro project, go to the Project tab and select “Address” to open the Address Tag Library.

2. Click “Import CSV…”

3. Choose to either remove old tags or replace the existing tags with the new ones.

4. Select the exported .CSV file from your PC and open the file to import into your EBPro project.

5. A message will pop up to indicate that all 4 tags have been imported successfully.

6. All 4 tags have been imported into the project and are now in the Address Tag Library as User-Defined Tags.

1. Double click on the bit lamp to open the bit lamp properties. Change the device to “Modbus TCP/IP Master” and press the settings button.

2. Check off “User-defined tag”.

3. Choose the Enable Bit for the address type.

4. Press “Apply” and “OK” to assign the Enable tag to the Bit Lamp.

5. Repeat the same steps for the remaining objects in the project.
