30.2. Operating Diagram of the Virtual Digital Outputs
Virtual digital outputs are software outputs that can be used as digital inputs from the following items:
• digital inputs
• digital outputs
• auxiliary digital outputs
• virtual digital outputs themselves.
They can be used for special functionality of the system, thus avoiding loop wiring on the same control board.
Example:
It can be necessary to control the status of the physical ENABLE contacts (ENABLE-A and ENABLE-B) of the system
to cause an external alarm to trip when MPL1 is selected in parameter C164 (DIGITAL INPUTS MENU).
Enable
P350 = 1: Digital
P351 = D21:Enable
P358 = TRUE
