10.2 LOGIC INPUTS SETUP 10.2.1 DESCRIPTION
Each logic input has two setpoints as shown below for Logic Input 1. The following points apply to all the logic
inputs:
• The state of a contact input is either ‘Open’ or ‘Closed’ and is determined directly from the rear terminal
inputs.
• The state of a virtual input is either ‘On’ or ‘Off’ and can be set by the user either from serial communica-
tions or from the
ACTUAL VALUES \ A1 STATUS \ VIRTUAL INPUTS
menu.
• The state of a logic input is either ‘Asserted’ or ‘Not-Asserted’.
• The state of logic input X (X = 1 to 14) is determined by combining the state of contact input X with the
state of virtual input X according to the
INPUT X ASSERTED LOGIC
setpoint; this is a limited form of program-
mable logic.
• The state of logic input Y (Y = 15 to 20) is determined by the state of virtual input Y 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.
