GR/GR7 type editor

After importing an FPWIN GR/FPWIN GR7 project into Control FPWIN Pro7, the program is loaded into the GR/GR7 type editor. This editor is similar to the LD editor but uses different default color settings, which you can adapt under Extras > Options > Program options > Fonts and colors.

You can edit, save and run your program inside the GR/GR7 type editor. Transfer of networks or functions into the LD editor is only possible using copy and paste. After pasting networks or parts of programs into the LD editor, please read the warnings and comments carefully to avoid any malfunctions caused by the different behavior of the GR/GR7 type editor.

Different behavior compared to LD/FBD editor

The GR/GR7 type editor handles read access from a variable after write access in the same network differently than the LD/FBD editors.

Danger for user and machinery

When copying&pasting networks between the GR/GR7 type editor and LD/FBD editors, how "read values from temporary copies" are processed can produce different results.
