• The state of Logic Input x (where x = 15 to 20) is determined by the state of Virtual Input x according to the INPUT y
ASSERTED LOGIC setpoint; this is a limited form of programmable logic.
• A logic function is invoked when its corresponding logic input is Asserted.
• One logic input can invoke many logic functions if required.
The
LOGIC INPUT n NAME setpoint allows the operator to assign a user-friendly description to logic inputs when replacing
panel switches with a virtual switch. This name will be displayed in the A1 STATUS ÖØ VIRTUAL INPUTS actual values menu.
The LOGIC INPUT n ASSERTED setpoint determines how to combine the Contact and Virtual Input states to determine the
Logic Input state. For Logic inputs 1 through 14, this setpoint may be assigned the following values:
For Logic Inputs 15 through 20, this setpoint may be assigned the following values:
VALUE LOGIC INPUT ASSERTED WHEN:
Disabled Never
