Control Input Wiring
Control Pushbuttons are wired to any of the digital input modules (8 I/O, 16I, I/R) in place of a field
contact input. The operation of these pushbuttons is either 'Momentary' which is a pulse on and off or
'Sustained' which is continuously on or off. The assignment of control inputs to input terminals is
configured via the web browser. The Control Pushbuttons can consist of the following types:
Pushbutton Operation
Silence Momentary
Acknowledge Momentary
Lamp Test Momentary
Full Function Momentary
Test
Reset Momentary
First Out Reset Momentary
Inhibit Sustained
The pushbuttons can be arranged to perform their function for all inputs and outputs or for specific
ones. This is configured via the web browser which can assign the pushbutton to a specific group
which is part of the input configuration.
