9.2.3 Which variables can be read?

All addresses and variables are readable. Variables or addresses should be entered in the format used in the Watch and Receipt Manager

9.2.4 Linking variables using WORD

In order to get the current value of the variable TEST from the POU PLC_PRG through the DDE interface in Microsoft WORD, a field (e.g., the date) must be inserted in WORD ('Insert' "Field"). Now when you click on the field with the right mouse button and select the command "Toggle Field Codes" you can change the field function for the chosen text. In our example, this would look as follows:

{ DDEAUTO WAGO-I/O-PRO 32 "C:\WAGO-I/O-PRO 32\PROJECT\IFMBSP.PRO" "PLC_PRG.TEST" }

Click on the field with the right mouse button again, then click on "Update Field" and the desired variable content appears in the text.

9.2.5 Linking variables using EXCEL

The following must be entered in Microsoft EXCEL before you can assign a variable to a cell.

=WAGO-I/O-PRO 32|'C:\WAGO-I/O-PRO 32\PROJECT\IFMBSP.PRO'!PLC_PRG.TEST'

When you click on 'Edit' then "Links", the result for this link will be:

Element: PLC_PRG.TEST

9.2.6 Accessing variables with Intouch

Link with your project a DDE Access Name <AccessName> with the application name WAGO-I/O-PRO 32 and the DDE topic name C:\WAGO- I/O-PRO 32\PROJECT\IFMBSP.PRO.
