Internal Multi-Function Output Terminal Selection
Sets the internal terminal action (ON / OFF) through digital keypad, communication or PLC.
The Local / Remote options on the digital keypad have the lowest priority. When the PLC uses
the entity DI, the corresponding function of original DI can still be triggered through virtual

You can choose N.O. (Pr.02-12 bit = 0) or N.C. (Pr.02-12 bit = 1) through the Pr.02-12 MI mode
to trigger the virtual terminals.
